By contrast, +the GNU General Public License is intended to guarantee your freedom to +share and change all versions of a program--to make sure it remains free +software for all its users. We, the Free Software Foundation, use the +GNU General Public License for most of our software; it applies also to +any other work released this way by its authors. You can apply it to +your programs, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +them if you wish), that you receive source code or can get it if you +want it, that you can change the software or use pieces of it in new +free programs, and that you know you can do these things. + + To protect your rights, we need to prevent others from denying you +these rights or asking you to surrender the rights. Therefore, you have +certain responsibilities if you distribute copies of the software, or if +you modify it: responsibilities to respect the freedom of others. + + For example, if you distribute copies of such a program, whether +gratis or for a fee, you must pass on to the recipients the same +freedoms that you received. You must make sure that they, too, receive +or can get the source code. And you must show them these terms so they +know their rights. + + Developers that use the GNU GPL protect your rights with two steps: +(1) assert copyright on the software, and (2) offer you this License +giving you legal permission to copy, distribute and/or modify it. + + For the developers' and authors' protection, the GPL clearly explains +that there is no warranty for this free software. For both users' and +authors' sake, the GPL requires that modified versions be marked as +changed, so that their problems will not be attributed erroneously to +authors of previous versions. + + Some devices are designed to deny users access to install or run +modified versions of the software inside them, although the manufacturer +can do so. This is fundamentally incompatible with the aim of +protecting users' freedom to change the software. The systematic +pattern of such abuse occurs in the area of products for individuals to +use, which is precisely where it is most unacceptable. Therefore, we +have designed this version of the GPL to prohibit the practice for those +products. If such problems arise substantially in other domains, we +stand ready to extend this provision to those domains in future versions +of the GPL, as needed to protect the freedom of users. + + Finally, every program is threatened constantly by software patents. +States should not allow patents to restrict development and use of +software on general-purpose computers, but in those that do, we wish to +avoid the special danger that patents applied to a free program could +make it effectively proprietary. To prevent this, the GPL assures that +patents cannot be used to render the program non-free. + + The precise terms and conditions for copying, distribution and +modification follow. + + TERMS AND CONDITIONS + + 0. Definitions. + + "This License" refers to version 3 of the GNU General Public License. + + "Copyright" also means copyright-like laws that apply to other kinds of +works, such as semiconductor masks. + + "The Program" refers to any copyrightable work licensed under this +License. Each licensee is addressed as "you". "Licensees" and +"recipients" may be individuals or organizations. + + To "modify" a work means to copy from or adapt all or part of the work +in a fashion requiring copyright permission, other than the making of an +exact copy. The resulting work is called a "modified version" of the +earlier work or a work "based on" the earlier work. + + A "covered work" means either the unmodified Program or a work based +on the Program. + + To "propagate" a work means to do anything with it that, without +permission, would make you directly or secondarily liable for +infringement under applicable copyright law, except executing it on a +computer or modifying a private copy. Propagation includes copying, +distribution (with or without modification), making available to the +public, and in some countries other activities as well. + + To "convey" a work means any kind of propagation that enables other +parties to make or receive copies. Mere interaction with a user through +a computer network, with no transfer of a copy, is not conveying. + + An interactive user interface displays "Appropriate Legal Notices" +to the extent that it includes a convenient and prominently visible +feature that (1) displays an appropriate copyright notice, and (2) +tells the user that there is no warranty for the work (except to the +extent that warranties are provided), that licensees may convey the +work under this License, and how to view a copy of this License. If +the interface presents a list of user commands or options, such as a +menu, a prominent item in the list meets this criterion. + + 1. Source Code. + + The "source code" for a work means the preferred form of the work +for making modifications to it. "Object code" means any non-source +form of a work. + + A "Standard Interface" means an interface that either is an official +standard defined by a recognized standards body, or, in the case of +interfaces specified for a particular programming language, one that +is widely used among developers working in that language. + + The "System Libraries" of an executable work include anything, other +than the work as a whole, that (a) is included in the normal form of +packaging a Major Component, but which is not part of that Major +Component, and (b) serves only to enable use of the work with that +Major Component, or to implement a Standard Interface for which an +implementation is available to the public in source code form. A +"Major Component", in this context, means a major essential component +(kernel, window system, and so on) of the specific operating system +(if any) on which the executable work runs, or a compiler used to +produce the work, or an object code interpreter used to run it. + + The "Corresponding Source" for a work in object code form means all +the source code needed to generate, install, and (for an executable +work) run the object code and to modify the work, including scripts to +control those activities. However, it does not include the work's +System Libraries, or general-purpose tools or generally available free +programs which are used unmodified in performing those activities but +which are not part of the work. For example, Corresponding Source +includes interface definition files associated with source files for +the work, and the source code for shared libraries and dynamically +linked subprograms that the work is specifically designed to require, +such as by intimate data communication or control flow between those +subprograms and other parts of the work. + + The Corresponding Source need not include anything that users +can regenerate automatically from other parts of the Corresponding +Source. + + The Corresponding Source for a work in source code form is that +same work. + + 2. Basic Permissions. + + All rights granted under this License are granted for the term of +copyright on the Program, and are irrevocable provided the stated +conditions are met. This License explicitly affirms your unlimited +permission to run the unmodified Program. The output from running a +covered work is covered by this License only if the output, given its +content, constitutes a covered work. This License acknowledges your +rights of fair use or other equivalent, as provided by copyright law. + + You may make, run and propagate covered works that you do not +convey, without conditions so long as your license otherwise remains +in force. You may convey covered works to others for the sole purpose +of having them make modifications exclusively for you, or provide you +with facilities for running those works, provided that you comply with +the terms of this License in conveying all material for which you do +not control copyright. Those thus making or running the covered works +for you must do so exclusively on your behalf, under your direction +and control, on terms that prohibit them from making any copies of +your copyrighted material outside their relationship with you. + + Conveying under any other circumstances is permitted solely under +the conditions stated below. Sublicensing is not allowed; section 10 +makes it unnecessary. + + 3. Protecting Users' Legal Rights From Anti-Circumvention Law. + + No covered work shall be deemed part of an effective technological +measure under any applicable law fulfilling obligations under article +11 of the WIPO copyright treaty adopted on 20 December 1996, or +similar laws prohibiting or restricting circumvention of such +measures. + + When you convey a covered work, you waive any legal power to forbid +circumvention of technological measures to the extent such circumvention +is effected by exercising rights under this License with respect to +the covered work, and you disclaim any intention to limit operation or +modification of the work as a means of enforcing, against the work's +users, your or third parties' legal rights to forbid circumvention of +technological measures. + + 4. Conveying Verbatim Copies. + + You may convey verbatim copies of the Program's source code as you +receive it, in any medium, provided that you conspicuously and +appropriately publish on each copy an appropriate copyright notice; +keep intact all notices stating that this License and any +non-permissive terms added in accord with section 7 apply to the code; +keep intact all notices of the absence of any warranty; and give all +recipients a copy of this License along with the Program. + + You may charge any price or no price for each copy that you convey, +and you may offer support or warranty protection for a fee. + + 5. Conveying Modified Source Versions. + + You may convey a work based on the Program, or the modifications to +produce it from the Program, in the form of source code under the +terms of section 4, provided that you also meet all of these conditions: + + a) The work must carry prominent notices stating that you modified + it, and giving a relevant date. + + b) The work must carry prominent notices stating that it is + released under this License and any conditions added under section + 7. This requirement modifies the requirement in section 4 to + "keep intact all notices". + + c) You must license the entire work, as a whole, under this + License to anyone who comes into possession of a copy. This + License will therefore apply, along with any applicable section 7 + additional terms, to the whole of the work, and all its parts, + regardless of how they are packaged. This License gives no + permission to license the work in any other way, but it does not + invalidate such permission if you have separately received it. + + d) If the work has interactive user interfaces, each must display + Appropriate Legal Notices; however, if the Program has interactive + interfaces that do not display Appropriate Legal Notices, your + work need not make them do so. + + A compilation of a covered work with other separate and independent +works, which are not by their nature extensions of the covered work, +and which are not combined with it such as to form a larger program, +in or on a volume of a storage or distribution medium, is called an +"aggregate" if the compilation and its resulting copyright are not +used to limit the access or legal rights of the compilation's users +beyond what the individual works permit. Inclusion of a covered work +in an aggregate does not cause this License to apply to the other +parts of the aggregate. + + 6. Conveying Non-Source Forms. + + You may convey a covered work in object code form under the terms +of sections 4 and 5, provided that you also convey the +machine-readable Corresponding Source under the terms of this License, +in one of these ways: + + a) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by the + Corresponding Source fixed on a durable physical medium + customarily used for software interchange. + + b) Convey the object code in, or embodied in, a physical product + (including a physical distribution medium), accompanied by a + written offer, valid for at least three years and valid for as + long as you offer spare parts or customer support for that product + model, to give anyone who possesses the object code either (1) a + copy of the Corresponding Source for all the software in the + product that is covered by this License, on a durable physical + medium customarily used for software interchange, for a price no + more than your reasonable cost of physically performing this + conveying of source, or (2) access to copy the + Corresponding Source from a network server at no charge. + + c) Convey individual copies of the object code with a copy of the + written offer to provide the Corresponding Source. This + alternative is allowed only occasionally and noncommercially, and + only if you received the object code with such an offer, in accord + with subsection 6b. + + d) Convey the object code by offering access from a designated + place (gratis or for a charge), and offer equivalent access to the + Corresponding Source in the same way through the same place at no + further charge. You need not require recipients to copy the + Corresponding Source along with the object code. If the place to + copy the object code is a network server, the Corresponding Source + may be on a different server (operated by you or a third party) + that supports equivalent copying facilities, provided you maintain + clear directions next to the object code saying where to find the + Corresponding Source. Regardless of what server hosts the + Corresponding Source, you remain obligated to ensure that it is + available for as long as needed to satisfy these requirements. + + e) Convey the object code using peer-to-peer transmission, provided + you inform other peers where the object code and Corresponding + Source of the work are being offered to the general public at no + charge under subsection 6d. + + A separable portion of the object code, whose source code is excluded +from the Corresponding Source as a System Library, need not be +included in conveying the object code work. + + A "User Product" is either (1) a "consumer product", which means any +tangible personal property which is normally used for personal, family, +or household purposes, or (2) anything designed or sold for incorporation +into a dwelling. In determining whether a product is a consumer product, +doubtful cases shall be resolved in favor of coverage. For a particular +product received by a particular user, "normally used" refers to a +typical or common use of that class of product, regardless of the status +of the particular user or of the way in which the particular user +actually uses, or expects or is expected to use, the product. A product +is a consumer product regardless of whether the product has substantial +commercial, industrial or non-consumer uses, unless such uses represent +the only significant mode of use of the product. + + "Installation Information" for a User Product means any methods, +procedures, authorization keys, or other information required to install +and execute modified versions of a covered work in that User Product from +a modified version of its Corresponding Source. The information must +suffice to ensure that the continued functioning of the modified object +code is in no case prevented or interfered with solely because +modification has been made. + + If you convey an object code work under this section in, or with, or +specifically for use in, a User Product, and the conveying occurs as +part of a transaction in which the right of possession and use of the +User Product is transferred to the recipient in perpetuity or for a +fixed term (regardless of how the transaction is characterized), the +Corresponding Source conveyed under this section must be accompanied +by the Installation Information. But this requirement does not apply +if neither you nor any third party retains the ability to install +modified object code on the User Product (for example, the work has +been installed in ROM). + + The requirement to provide Installation Information does not include a +requirement to continue to provide support service, warranty, or updates +for a work that has been modified or installed by the recipient, or for +the User Product in which it has been modified or installed. Access to a +network may be denied when the modification itself materially and +adversely affects the operation of the network or violates the rules and +protocols for communication across the network. + + Corresponding Source conveyed, and Installation Information provided, +in accord with this section must be in a format that is publicly +documented (and with an implementation available to the public in +source code form), and must require no special password or key for +unpacking, reading or copying. + + 7. Additional Terms. + + "Additional permissions" are terms that supplement the terms of this +License by making exceptions from one or more of its conditions. +Additional permissions that are applicable to the entire Program shall +be treated as though they were included in this License, to the extent +that they are valid under applicable law. If additional permissions +apply only to part of the Program, that part may be used separately +under those permissions, but the entire Program remains governed by +this License without regard to the additional permissions. + + When you convey a copy of a covered work, you may at your option +remove any additional permissions from that copy, or from any part of +it. (Additional permissions may be written to require their own +removal in certain cases when you modify the work.) You may place +additional permissions on material, added by you to a covered work, +for which you have or can give appropriate copyright permission. + + Notwithstanding any other provision of this License, for material you +add to a covered work, you may (if authorized by the copyright holders of +that material) supplement the terms of this License with terms: + + a) Disclaiming warranty or limiting liability differently from the + terms of sections 15 and 16 of this License; or + + b) Requiring preservation of specified reasonable legal notices or + author attributions in that material or in the Appropriate Legal + Notices displayed by works containing it; or + + c) Prohibiting misrepresentation of the origin of that material, or + requiring that modified versions of such material be marked in + reasonable ways as different from the original version; or + + d) Limiting the use for publicity purposes of names of licensors or + authors of the material; or + + e) Declining to grant rights under trademark law for use of some + trade names, trademarks, or service marks; or + + f) Requiring indemnification of licensors and authors of that + material by anyone who conveys the material (or modified versions of + it) with contractual assumptions of liability to the recipient, for + any liability that these contractual assumptions directly impose on + those licensors and authors. + + All other non-permissive additional terms are considered "further +restrictions" within the meaning of section 10. If the Program as you +received it, or any part of it, contains a notice stating that it is +governed by this License along with a term that is a further +restriction, you may remove that term. If a license document contains +a further restriction but permits relicensing or conveying under this +License, you may add to a covered work material governed by the terms +of that license document, provided that the further restriction does +not survive such relicensing or conveying. + + If you add terms to a covered work in accord with this section, you +must place, in the relevant source files, a statement of the +additional terms that apply to those files, or a notice indicating +where to find the applicable terms. + + Additional terms, permissive or non-permissive, may be stated in the +form of a separately written license, or stated as exceptions; +the above requirements apply either way. + + 8. Termination. + + You may not propagate or modify a covered work except as expressly +provided under this License. Any attempt otherwise to propagate or +modify it is void, and will automatically terminate your rights under +this License (including any patent licenses granted under the third +paragraph of section 11). + + However, if you cease all violation of this License, then your +license from a particular copyright holder is reinstated (a) +provisionally, unless and until the copyright holder explicitly and +finally terminates your license, and (b) permanently, if the copyright +holder fails to notify you of the violation by some reasonable means +prior to 60 days after the cessation. + + Moreover, your license from a particular copyright holder is +reinstated permanently if the copyright holder notifies you of the +violation by some reasonable means, this is the first time you have +received notice of violation of this License (for any work) from that +copyright holder, and you cure the violation prior to 30 days after +your receipt of the notice. + + Termination of your rights under this section does not terminate the +licenses of parties who have received copies or rights from you under +this License. If your rights have been terminated and not permanently +reinstated, you do not qualify to receive new licenses for the same +material under section 10. + + 9. Acceptance Not Required for Having Copies. + + You are not required to accept this License in order to receive or +run a copy of the Program. Ancillary propagation of a covered work +occurring solely as a consequence of using peer-to-peer transmission +to receive a copy likewise does not require acceptance. However, +nothing other than this License grants you permission to propagate or +modify any covered work. These actions infringe copyright if you do +not accept this License. Therefore, by modifying or propagating a +covered work, you indicate your acceptance of this License to do so. + + 10. Automatic Licensing of Downstream Recipients. + + Each time you convey a covered work, the recipient automatically +receives a license from the original licensors, to run, modify and +propagate that work, subject to this License. You are not responsible +for enforcing compliance by third parties with this License. + + An "entity transaction" is a transaction transferring control of an +organization, or substantially all assets of one, or subdividing an +organization, or merging organizations. If propagation of a covered +work results from an entity transaction, each party to that +transaction who receives a copy of the work also receives whatever +licenses to the work the party's predecessor in interest had or could +give under the previous paragraph, plus a right to possession of the +Corresponding Source of the work from the predecessor in interest, if +the predecessor has it or can get it with reasonable efforts. + + You may not impose any further restrictions on the exercise of the +rights granted or affirmed under this License. For example, you may +not impose a license fee, royalty, or other charge for exercise of +rights granted under this License, and you may not initiate litigation +(including a cross-claim or counterclaim in a lawsuit) alleging that +any patent claim is infringed by making, using, selling, offering for +sale, or importing the Program or any portion of it. + + 11. Patents. + + A "contributor" is a copyright holder who authorizes use under this +License of the Program or a work on which the Program is based. The +work thus licensed is called the contributor's "contributor version". + + A contributor's "essential patent claims" are all patent claims +owned or controlled by the contributor, whether already acquired or +hereafter acquired, that would be infringed by some manner, permitted +by this License, of making, using, or selling its contributor version, +but do not include claims that would be infringed only as a +consequence of further modification of the contributor version. For +purposes of this definition, "control" includes the right to grant +patent sublicenses in a manner consistent with the requirements of +this License. + + Each contributor grants you a non-exclusive, worldwide, royalty-free +patent license under the contributor's essential patent claims, to +make, use, sell, offer for sale, import and otherwise run, modify and +propagate the contents of its contributor version. + + In the following three paragraphs, a "patent license" is any express +agreement or commitment, however denominated, not to enforce a patent +(such as an express permission to practice a patent or covenant not to +sue for patent infringement). To "grant" such a patent license to a +party means to make such an agreement or commitment not to enforce a +patent against the party. + + If you convey a covered work, knowingly relying on a patent license, +and the Corresponding Source of the work is not available for anyone +to copy, free of charge and under the terms of this License, through a +publicly available network server or other readily accessible means, +then you must either (1) cause the Corresponding Source to be so +available, or (2) arrange to deprive yourself of the benefit of the +patent license for this particular work, or (3) arrange, in a manner +consistent with the requirements of this License, to extend the patent +license to downstream recipients. "Knowingly relying" means you have +actual knowledge that, but for the patent license, your conveying the +covered work in a country, or your recipient's use of the covered work +in a country, would infringe one or more identifiable patents in that +country that you have reason to believe are valid. + + If, pursuant to or in connection with a single transaction or +arrangement, you convey, or propagate by procuring conveyance of, a +covered work, and grant a patent license to some of the parties +receiving the covered work authorizing them to use, propagate, modify +or convey a specific copy of the covered work, then the patent license +you grant is automatically extended to all recipients of the covered +work and works based on it. + + A patent license is "discriminatory" if it does not include within +the scope of its coverage, prohibits the exercise of, or is +conditioned on the non-exercise of one or more of the rights that are +specifically granted under this License. You may not convey a covered +work if you are a party to an arrangement with a third party that is +in the business of distributing software, under which you make payment +to the third party based on the extent of your activity of conveying +the work, and under which the third party grants, to any of the +parties who would receive the covered work from you, a discriminatory +patent license (a) in connection with copies of the covered work +conveyed by you (or copies made from those copies), or (b) primarily +for and in connection with specific products or compilations that +contain the covered work, unless you entered into that arrangement, +or that patent license was granted, prior to 28 March 2007. + + Nothing in this License shall be construed as excluding or limiting +any implied license or other defenses to infringement that may +otherwise be available to you under applicable patent law. + + 12. No Surrender of Others' Freedom. + + If conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot convey a +covered work so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you may +not convey it at all. For example, if you agree to terms that obligate you +to collect a royalty for further conveying from those to whom you convey +the Program, the only way you could satisfy both those terms and this +License would be to refrain entirely from conveying the Program. + + 13. Use with the GNU Affero General Public License. + + Notwithstanding any other provision of this License, you have +permission to link or combine any covered work with a work licensed +under version 3 of the GNU Affero General Public License into a single +combined work, and to convey the resulting work. The terms of this +License will continue to apply to the part which is the covered work, +but the special requirements of the GNU Affero General Public License, +section 13, concerning interaction through a network will apply to the +combination as such. + + 14. Revised Versions of this License. + + The Free Software Foundation may publish revised and/or new versions of +the GNU General Public License from time to time. Such new versions will +be similar in spirit to the present version, but may differ in detail to +address new problems or concerns. + + Each version is given a distinguishing version number. If the +Program specifies that a certain numbered version of the GNU General +Public License "or any later version" applies to it, you have the +option of following the terms and conditions either of that numbered +version or of any later version published by the Free Software +Foundation. If the Program does not specify a version number of the +GNU General Public License, you may choose any version ever published +by the Free Software Foundation. + + If the Program specifies that a proxy can decide which future +versions of the GNU General Public License can be used, that proxy's +public statement of acceptance of a version permanently authorizes you +to choose that version for the Program. + + Later license versions may give you additional or different +permissions. However, no additional obligations are imposed on any +author or copyright holder as a result of your choosing to follow a +later version. + + 15. Disclaimer of Warranty. + + THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY +APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT +HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY +OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, +THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM +IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF +ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. Limitation of Liability. + + IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING +WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS +THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY +GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE +USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF +DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD +PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), +EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF +SUCH DAMAGES. + + 17. Interpretation of Sections 15 and 16. + + If the disclaimer of warranty and limitation of liability provided +above cannot be given local legal effect according to their terms, +reviewing courts shall apply local law that most closely approximates +an absolute waiver of all civil liability in connection with the +Program, unless a warranty or assumption of liability accompanies a +copy of the Program in return for a fee. + + END OF TERMS AND CONDITIONS + + How to Apply These Terms to Your New Programs + + If you develop a new program, and you want it to be of the greatest +possible use to the public, the best way to achieve this is to make it +free software which everyone can redistribute and change under these terms. + + To do so, attach the following notices to the program. It is safest +to attach them to the start of each source file to most effectively +state the exclusion of warranty; and each file should have at least +the "copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This program is free software: you can redistribute it and/or modify + it under the terms of the GNU General Public License as published by + the Free Software Foundation, either version 3 of the License, or + (at your option) any later version. + + This program is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the + GNU General Public License for more details. + + You should have received a copy of the GNU General Public License + along with this program. If not, see . + +Also add information on how to contact you by electronic and paper mail. + + If the program does terminal interaction, make it output a short +notice like this when it starts in an interactive mode: + + Copyright (C) + This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'. + This is free software, and you are welcome to redistribute it + under certain conditions; type `show c' for details. + +The hypothetical commands `show w' and `show c' should show the appropriate +parts of the General Public License. Of course, your program's commands +might be different; for a GUI interface, you would use an "about box". + + You should also get your employer (if you work as a programmer) or school, +if any, to sign a "copyright disclaimer" for the program, if necessary. +For more information on this, and how to apply and follow the GNU GPL, see +. + + The GNU General Public License does not permit incorporating your program +into proprietary programs. If your program is a subroutine library, you +may consider it more useful to permit linking proprietary applications with +the library. If this is what you want to do, use the GNU Lesser General +Public License instead of this License.

Some of the backends in examples/ do that. + (If you set the NavEnableSetMousePos flag but don't honor 'io.WantSetMousePos' properly, Dear ImGui will misbehave as it will see your mouse moving back & forth!) + (In a setup when you may not have easy control over the mouse cursor, e.g. uSynergy.c doesn't expose moving remote mouse cursor, you may want + to set a boolean to ignore your other external mouse positions until the external source is moved again.) + + + PROGRAMMER GUIDE + ================ + + READ FIRST + ---------- + - Remember to check the wonderful Wiki: https://github.com/ocornut/imgui/wiki + - Your code creates the UI every frame of your application loop, if your code doesn't run the UI is gone! + The UI can be highly dynamic, there are no construction or destruction steps, less superfluous + data retention on your side, less state duplication, less state synchronization, fewer bugs. + - Call and read ImGui::ShowDemoWindow() for demo code demonstrating most features. + Or browse https://pthom.github.io/imgui_manual_online/manual/imgui_manual.html for interactive web version. + - The library is designed to be built from sources. Avoid pre-compiled binaries and packaged versions. See imconfig.h to configure your build. + - Dear ImGui is an implementation of the IMGUI paradigm (immediate-mode graphical user interface, a term coined by Casey Muratori). + You can learn about IMGUI principles at http://www.johno.se/book/imgui.html, http://mollyrocket.com/861 & more links in Wiki. + - Dear ImGui is a "single pass" rasterizing implementation of the IMGUI paradigm, aimed at ease of use and high-performances. + For every application frame, your UI code will be called only once. This is in contrast to e.g. Unity's implementation of an IMGUI, + where the UI code is called multiple times ("multiple passes") from a single entry point. There are pros and cons to both approaches. + - Our origin is on the top-left. In axis aligned bounding boxes, Min = top-left, Max = bottom-right. + - Please make sure you have asserts enabled (IM_ASSERT redirects to assert() by default, but can be redirected). + If you get an assert, read the messages and comments around the assert. + - This codebase aims to be highly optimized: + - A typical idle frame should never call malloc/free. + - We rely on a maximum of constant-time or O(N) algorithms. Limiting searches/scans as much as possible. + - We put particular energy in making sure performances are decent with typical "Debug" build settings as well. + Which mean we tend to avoid over-relying on "zero-cost abstraction" as they aren't zero-cost at all. + - This codebase aims to be both highly opinionated and highly flexible: + - This code works because of the things it choose to solve or not solve. + - C++: this is a pragmatic C-ish codebase: we don't use fancy C++ features, we don't include C++ headers, + and ImGui:: is a namespace. We rarely use member functions (and when we did, I am mostly regretting it now). + This is to increase compatibility, increase maintainability and facilitate use from other languages. + - C++: ImVec2/ImVec4 do not expose math operators by default, because it is expected that you use your own math types. + See FAQ "How can I use my own math types instead of ImVec2/ImVec4?" for details about setting up imconfig.h for that. + We can can optionally export math operators for ImVec2/ImVec4 using IMGUI_DEFINE_MATH_OPERATORS, which we use internally. + - C++: pay attention that ImVector<> manipulates plain-old-data and does not honor construction/destruction + (so don't use ImVector in your code or at our own risk!). + - Building: We don't use nor mandate a build system for the main library. + This is in an effort to ensure that it works in the real world aka with any esoteric build setup. + This is also because providing a build system for the main library would be of little-value. + The build problems are almost never coming from the main library but from specific backends. + + + HOW TO UPDATE TO A NEWER VERSION OF DEAR IMGUI + ---------------------------------------------- + - Update submodule or copy/overwrite every file. + - About imconfig.h: + - You may modify your copy of imconfig.h, in this case don't overwrite it. + - or you may locally branch to modify imconfig.h and merge/rebase latest. + - or you may '#define IMGUI_USER_CONFIG "my_config_file.h"' globally from your build system to + specify a custom path for your imconfig.h file and instead not have to modify the default one. + + - Overwrite all the sources files except for imconfig.h (if you have modified your copy of imconfig.h) + - Or maintain your own branch where you have imconfig.h modified as a top-most commit which you can regularly rebase over "master". + - You can also use '#define IMGUI_USER_CONFIG "my_config_file.h" to redirect configuration to your own file. + - Read the "API BREAKING CHANGES" section (below). This is where we list occasional API breaking changes. + If a function/type has been renamed / or marked obsolete, try to fix the name in your code before it is permanently removed + from the public API. If you have a problem with a missing function/symbols, search for its name in the code, there will + likely be a comment about it. Please report any issue to the GitHub page! + - To find out usage of old API, you can add '#define IMGUI_DISABLE_OBSOLETE_FUNCTIONS' in your configuration file. + - Try to keep your copy of Dear ImGui reasonably up to date! + + + GETTING STARTED WITH INTEGRATING DEAR IMGUI IN YOUR CODE/ENGINE + --------------------------------------------------------------- + - See https://github.com/ocornut/imgui/wiki/Getting-Started. + - Run and study the examples and demo in imgui_demo.cpp to get acquainted with the library. + - In the majority of cases you should be able to use unmodified backends files available in the backends/ folder. + - Add the Dear ImGui source files + selected backend source files to your projects or using your preferred build system. + It is recommended you build and statically link the .cpp files as part of your project and NOT as a shared library (DLL). + - You can later customize the imconfig.h file to tweak some compile-time behavior, such as integrating Dear ImGui types with your own maths types. + - When using Dear ImGui, your programming IDE is your friend: follow the declaration of variables, functions and types to find comments about them. + - Dear ImGui never touches or knows about your GPU state. The only function that knows about GPU is the draw function that you provide. + Effectively it means you can create widgets at any time in your code, regardless of considerations of being in "update" vs "render" + phases of your own application. All rendering information is stored into command-lists that you will retrieve after calling ImGui::Render(). + - Refer to the backends and demo applications in the examples/ folder for instruction on how to setup your code. + - If you are running over a standard OS with a common graphics API, you should be able to use unmodified imgui_impl_*** files from the examples/ folder. + + + HOW A SIMPLE APPLICATION MAY LOOK LIKE + -------------------------------------- + + USING THE EXAMPLE BACKENDS (= imgui_impl_XXX.cpp files from the backends/ folder). + The sub-folders in examples/ contain examples applications following this structure. + + // Application init: create a dear imgui context, setup some options, load fonts + ImGui::CreateContext(); + ImGuiIO& io = ImGui::GetIO(); + // TODO: Set optional io.ConfigFlags values, e.g. 'io.ConfigFlags |= ImGuiConfigFlags_NavEnableKeyboard' to enable keyboard controls. + // TODO: Fill optional fields of the io structure later. + // TODO: Load TTF/OTF fonts if you don't want to use the default font. + + // Initialize helper Platform and Renderer backends (here we are using imgui_impl_win32.cpp and imgui_impl_dx11.cpp) + ImGui_ImplWin32_Init(hwnd); + ImGui_ImplDX11_Init(g_pd3dDevice, g_pd3dDeviceContext); + + // Application main loop + while (true) + { + // Feed inputs to dear imgui, start new frame + ImGui_ImplDX11_NewFrame(); + ImGui_ImplWin32_NewFrame(); + ImGui::NewFrame(); + + // Any application code here + ImGui::Text("Hello, world!"); + + // Render dear imgui into framebuffer + ImGui::Render(); + ImGui_ImplDX11_RenderDrawData(ImGui::GetDrawData()); + g_pSwapChain->Present(1, 0); + } + + // Shutdown + ImGui_ImplDX11_Shutdown(); + ImGui_ImplWin32_Shutdown(); + ImGui::DestroyContext(); + + To decide whether to dispatch mouse/keyboard inputs to Dear ImGui to the rest of your application, + you should read the 'io.WantCaptureMouse', 'io.WantCaptureKeyboard' and 'io.WantTextInput' flags!

It means that: + - reference to hard-coded positions such as in SetNextWindowPos(ImVec2(0,0)) are probably not what you want anymore. + you may use GetMainViewport()->Pos to offset hard-coded positions, e.g. SetNextWindowPos(GetMainViewport()->Pos) + - likewise io.MousePos and GetMousePos() will use OS coordinates. + If you query mouse positions to interact with non-imgui coordinates you will need to offset them, e.g. subtract GetWindowViewport()->Pos. + + - 2026/01/08 (1.92.6) - Commented out legacy names obsoleted in 1.90 (Sept 2023): 'BeginChildFrame()' --> 'BeginChild()' with 'ImGuiChildFlags_FrameStyle'. 'EndChildFrame()' --> 'EndChild()'. 'ShowStackToolWindow()' --> 'ShowIDStackToolWindow()'. 'IM_OFFSETOF()' --> 'offsetof()'. + - 2026/01/07 (1.92.6) - Popups: changed compile-time 'ImGuiPopupFlags popup_flags = 1' default value to be '= 0' for BeginPopupContextItem(), BeginPopupContextWindow(), BeginPopupContextVoid(), OpenPopupOnItemClick(). Default value has same meaning before and after. + - Refer to GitHub topic #9157 if you have any question. + - Before this version, those functions had a 'ImGuiPopupFlags popup_flags = 1' default value in their function signature. + Explicitly passing a literal 0 meant ImGuiPopupFlags_MouseButtonLeft. The default literal 1 meant ImGuiPopupFlags_MouseButtonRight. + This was introduced by a change on 2020/06/23 (1.77) while changing the signature from 'int mouse_button' to 'ImGuiPopupFlags popup_flags' and trying to preserve then-legacy behavior. + We have now changed this behavior to cleanup a very old API quirk, facilitate use by bindings, and to remove the last and error-prone non-zero default value. + Also because we deemed it extremely rare to use those helper functions with the Left mouse button! As using the LMB would generally be triggered via another widget, e.g. a Button() + a OpenPopup()/BeginPopup() call. + - Before: The default = 1 means ImGuiPopupFlags_MouseButtonRight. Explicitly passing a literal 0 means ImGuiPopupFlags_MouseButtonLeft. + - After: The default = 0 means ImGuiPopupFlags_MouseButtonRight. Explicitly passing a literal 1 also means ImGuiPopupFlags_MouseButtonRight (if legacy behavior are enabled) or will assert (if legacy behavior are disabled). + - TL;DR: if you don't want to use right mouse button for popups, always specify it explicitly using a named ImGuiPopupFlags_MouseButtonXXXX value. + Recap: + - BeginPopupContextItem("foo"); // Behavior unchanged (use Right button) + - BeginPopupContextItem("foo", ImGuiPopupFlags_MouseButtonLeft); // Behavior unchanged (use Left button) + - BeginPopupContextItem("foo", ImGuiPopupFlags_MouseButtonLeft | xxx); // Behavior unchanged (use Left button + flags) + - BeginPopupContextItem("foo", ImGuiPopupFlags_MouseButtonRight | xxx); // Behavior unchanged (use Right button + flags) + - BeginPopupContextItem("foo", 1); // Behavior unchanged (as a courtesy we legacy interpret 1 as ImGuiPopupFlags_MouseButtonRight, will assert if disabling legacy behaviors. + - BeginPopupContextItem("foo", 0); // !! Behavior changed !! Was Left button. Now will defaults to Right button! --> Use ImGuiPopupFlags_MouseButtonLeft. + - BeginPopupContextItem("foo", ImGuiPopupFlags_NoReopen); // !! Behavior changed !! Was Left button + flags. Now will defaults to Right button! --> Use ImGuiPopupFlags_MouseButtonLeft | xxx. + - 2025/12/23 (1.92.6) - Fonts:AddFontDefault() now automatically selects an embedded font between the new scalable AddFontDefaultVector() and the classic pixel-clean AddFontDefaultBitmap(). + The default selection is based on (style.FontSizeBase * FontScaleMain * FontScaleDpi) reaching a small threshold. Prefer calling either based on your own logic. You can call AddFontDefaultBitmap() to ensure legacy behavior. + - 2025/12/23 (1.92.6) - Fonts: removed ImFontConfig::PixelSnapV added in 1.92 which turns out is unnecessary (and misdocumented). Post-rescale GlyphOffset is always rounded. + - 2025/12/17 (1.92.6) - Renamed helper macro IM_ARRAYSIZE() -> IM_COUNTOF(). Kept redirection/legacy name for now. + - 2025/12/11 (1.92.6) - Hashing: handling of "###" operator to reset to seed within a string identifier doesn't include the "###" characters in the output hash anymore. + - Before: GetID("Hello###World") == GetID("###World") != GetID("World"); + - Now: GetID("Hello###World") == GetID("###World") == GetID("World"); + - This has the property of facilitating concatenating and manipulating identifiers using "###", and will allow fixing other dangling issues. + - This will invalidate hashes (stored in .ini data) for Tables and Windows that are using the "###" operators. (#713, #1698) + - 2025/11/24 (1.92.6) - Fonts: Fixed handling of `ImFontConfig::FontDataOwnedByAtlas = false` which did erroneously make a copy of the font data, essentially defeating the purpose of this flag and wasting memory. + (trivia: undetected since July 2015, this is perhaps the oldest bug in Dear ImGui history, albeit for a rarely used feature, see #9086) + HOWEVER, fixing this bug is likely to surface bugs in user code using `FontDataOwnedByAtlas = false`. + - Prior to 1.92, font data only needed to be available during the atlas->AddFontXXX() call. + - Since 1.92, font data needs to available until atlas->RemoveFont(), or more typically until a shutdown of the owning context or font atlas. + - The fact that handling of `FontDataOwnedByAtlas = false` was broken bypassed the issue altogether. + - 2025/11/06 (1.92.5) - BeginChild: commented out some legacy names which were obsoleted in 1.90.0 (Nov 2023), 1.90.9 (July 2024), 1.91.1 (August 2024): + - ImGuiChildFlags_Border --> ImGuiChildFlags_Borders + - ImGuiWindowFlags_NavFlattened --> ImGuiChildFlags_NavFlattened (moved to ImGuiChildFlags).

Calling io.ClearInputKeys() is enough. + - 2025/11/06 (1.92.5) - Commented out legacy SetItemAllowOverlap() obsoleted in 1.89.7: this never worked right. Use SetNextItemAllowOverlap() _before_ item instead. + - 2025/10/14 (1.92.4) - TreeNode, Selectable, Clipper: commented out legacy names which were obsoleted in 1.89.7 (July 2023) and 1.89.9 (Sept 2023); + - ImGuiTreeNodeFlags_AllowItemOverlap --> ImGuiTreeNodeFlags_AllowOverlap + - ImGuiSelectableFlags_AllowItemOverlap --> ImGuiSelectableFlags_AllowOverlap + - ImGuiListClipper::IncludeRangeByIndices() --> ImGuiListClipper::IncludeItemsByIndex() + - 2025/09/22 (1.92.4) - Viewports: renamed io.ConfigViewportPlatformFocusSetsImGuiFocus to io.ConfigViewportsPlatformFocusSetsImGuiFocus. Was a typo in the first place. (#6299, #6462) + - 2025/08/08 (1.92.2) - Backends: SDL_GPU3: Changed ImTextureID type from SDL_GPUTextureSamplerBinding* to SDL_GPUTexture*, which is more natural and easier for user to manage. If you need to change the current sampler, you can access the ImGui_ImplSDLGPU3_RenderState struct. (#8866, #8163, #7998, #7988) + - 2025/07/31 (1.92.2) - Tabs: Renamed ImGuiTabBarFlags_FittingPolicyResizeDown to ImGuiTabBarFlags_FittingPolicyShrink. Kept inline redirection enum (will obsolete). + - 2025/06/25 (1.92.0) - Layout: commented out legacy ErrorCheckUsingSetCursorPosToExtendParentBoundaries() fallback obsoleted in 1.89 (August 2022) which allowed a SetCursorPos()/SetCursorScreenPos() call WITHOUT AN ITEM + to extend parent window/cell boundaries. Replaced with assert/tooltip that would already happens if previously using IMGUI_DISABLE_OBSOLETE_FUNCTIONS.

They will be useful once we merge font changes.** + [there was a bug on 2025/06/12: when using the old config flags names, they were not imported correctly into the new ones, fixed on 2025/09/12] + - 2025/06/11 (1.92.0) - THIS VERSION CONTAINS THE LARGEST AMOUNT OF BREAKING CHANGES SINCE 2015! I TRIED REALLY HARD TO KEEP THEM TO A MINIMUM, REDUCE THE AMOUNT OF INTERFERENCES, BUT INEVITABLY SOME USERS WILL BE AFFECTED. + IN ORDER TO HELP US IMPROVE THE TRANSITION PROCESS, INCL. DOCUMENTATION AND COMMENTS, PLEASE REPORT **ANY** DOUBT, CONFUSION, QUESTIONS, FEEDBACK TO: https://github.com/ocornut/imgui/issues/ + As part of the plan to reduce impact of API breaking changes, several unfinished changes/features/refactors related to font and text systems and scaling will be part of subsequent releases (1.92.1+). + If you are updating from an old version, and expecting a massive or difficult update, consider first updating to 1.91.9 to reduce the amount of changes. + - Hard to read? Refer to 'docs/Changelog.txt' for a less compact and more complete version of this! + - Fonts: **IMPORTANT**: if your app was solving the OSX/iOS Retina screen specific logical vs display scale problem by setting io.DisplayFramebufferScale (e.g. to 2.0f) + setting io.FontGlobalScale (e.g. to 1.0f/2.0f) + loading fonts at scaled sizes (e.g. size X * 2.0f): + This WILL NOT map correctly to the new system! Because font will rasterize as requested size. + - With a legacy backend (< 1.92): Instead of setting io.FontGlobalScale = 1.0f/N -> set ImFontCfg::RasterizerDensity = N. This already worked before, but is now pretty much required. + - With a new backend (1.92+): This should be all automatic. FramebufferScale is automatically used to set current font RasterizerDensity. FramebufferScale is a per-viewport property provided by backend through the Platform_GetWindowFramebufferScale() handler in 'docking' branch. + - Fonts: **IMPORTANT** on Font Sizing: Before 1.92, fonts were of a single size. They can now be dynamically sized. + - PushFont() API now has a REQUIRED size parameter. + - Before 1.92: PushFont() always used font "default" size specified in AddFont() call. It is equivalent to calling PushFont(font, font->LegacySize). + - Since 1.92: PushFont(font, 0.0f) preserve the current font size which is a shared value. + - To use old behavior: use 'ImGui::PushFont(font, font->LegacySize)' at call site. + - Kept inline single parameter function. Will obsolete. + - Fonts: **IMPORTANT** on Font Merging: + - When searching for a glyph in multiple merged fonts: we search for the FIRST font source which contains the desired glyph. + Because the user doesn't need to provide glyph ranges any more, it is possible that a glyph that you expected to fetch from a secondary/merged icon font may be erroneously fetched from the primary font. + - When searching for a glyph in multiple merged fonts: we now search for the FIRST font source which contains the desired glyph. This is technically a different behavior than before! + - e.g. If you are merging fonts you may have glyphs that you expected to load from Font Source 2 which exists in Font Source 1. + After the update and when using a new backend, those glyphs may now loaded from Font Source 1! + - We added `ImFontConfig::GlyphExcludeRanges[]` to specify ranges to exclude from a given font source: + // Add Font Source 1 but ignore ICON_MIN_FA..ICON_MAX_FA range + static ImWchar exclude_ranges[] = { ICON_MIN_FA, ICON_MAX_FA, 0 }; + ImFontConfig cfg1; + cfg1.GlyphExcludeRanges = exclude_ranges; + io.Fonts->AddFontFromFileTTF("segoeui.ttf", 0.0f, &cfg1); + // Add Font Source 2, which expects to use the range above + ImFontConfig cfg2; + cfg2.MergeMode = true; + io.Fonts->AddFontFromFileTTF("FontAwesome4.ttf", 0.0f, &cfg2); + - You can use `Metrics/Debugger->Fonts->Font->Input Glyphs Overlap Detection Tool` to see list of glyphs available in multiple font sources. This can facilitate understanding which font input is providing which glyph. + - Fonts: **IMPORTANT** on Thread Safety: + - A few functions such as font->CalcTextSizeA() were, by sheer luck (== accidentally) thread-safe even thou we had never provided that guarantee. They are definitively not thread-safe anymore as new glyphs may be loaded. + - Fonts: ImFont::FontSize was removed and does not make sense anymore. ImFont::LegacySize is the size passed to AddFont(). + - Fonts: Removed support for PushFont(NULL) which was a shortcut for "default font". + - Fonts: Renamed/moved 'io.FontGlobalScale' to 'style.FontScaleMain'. + - Textures: all API functions taking a 'ImTextureID' parameter are now taking a 'ImTextureRef'. Affected functions are: ImGui::Image(), ImGui::ImageWithBg(), ImGui::ImageButton(), ImDrawList::AddImage(), ImDrawList::AddImageQuad(), ImDrawList::AddImageRounded(). + - Fonts: obsoleted ImFontAtlas::GetTexDataAsRGBA32(), GetTexDataAsAlpha8(), Build(), SetTexID(), IsBuilt() functions. The new protocol for backends to handle textures doesn't need them. Kept redirection functions (will obsolete). + - Fonts: ImFontConfig::OversampleH/OversampleV default to automatic (== 0) since v1.91.8. It is quite important you keep it automatic until we decide if we want to provide a way to express finer policy, otherwise you will likely waste texture space when using large glyphs. Note that the imgui_freetype backend doesn't use and does not need oversampling. + - Fonts: specifying glyph ranges is now unnecessary. The value of ImFontConfig::GlyphRanges[] is only useful for legacy backends. All GetGlyphRangesXXXX() functions are now marked obsolete: GetGlyphRangesDefault(), GetGlyphRangesGreek(), GetGlyphRangesKorean(), GetGlyphRangesJapanese(), GetGlyphRangesChineseSimplifiedCommon(), GetGlyphRangesChineseFull(), GetGlyphRangesCyrillic(), GetGlyphRangesThai(), GetGlyphRangesVietnamese(). + - Fonts: removed ImFontAtlas::TexDesiredWidth to enforce a texture width. (#327) + - Fonts: if you create and manage ImFontAtlas instances yourself (instead of relying on ImGuiContext to create one), you'll need to call ImFontAtlasUpdateNewFrame() yourself. An assert will trigger if you don't. + - Fonts: obsolete ImGui::SetWindowFontScale() which is not useful anymore. Prefer using 'PushFont(NULL, style.FontSizeBase * factor)' or to manipulate other scaling factors. + - Fonts: obsoleted ImFont::Scale which is not useful anymore. + - Fonts: generally reworked Internals of ImFontAtlas and ImFont. While in theory a vast majority of users shouldn't be affected, some use cases or extensions might be. Among other things: + - ImDrawCmd::TextureId has been changed to ImDrawCmd::TexRef. + - ImFontAtlas::TexID has been changed to ImFontAtlas::TexRef. + - ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[] + - ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourceCount. + - Each ImFont has a number of ImFontBaked instances corresponding to actively used sizes. ImFont::GetFontBaked(size) retrieves the one for a given size. + - Fields moved from ImFont to ImFontBaked: IndexAdvanceX[], Glyphs[], Ascent, Descent, FindGlyph(), FindGlyphNoFallback(), GetCharAdvance(). + - Fields moved from ImFontAtlas to ImFontAtlas->Tex: ImFontAtlas::TexWidth => TexData->Width, ImFontAtlas::TexHeight => TexData->Height, ImFontAtlas::TexPixelsAlpha8/TexPixelsRGBA32 => TexData->GetPixels(). + - Widget code may use ImGui::GetFontBaked() instead of ImGui::GetFont() to access font data for current font at current font size (and you may use font->GetFontBaked(size) to access it for any other size.) + - Fonts: (users of imgui_freetype): renamed ImFontAtlas::FontBuilderFlags to ImFontAtlas::FontLoaderFlags. Renamed ImFontConfig::FontBuilderFlags to ImFontConfig::FontLoaderFlags. Renamed ImGuiFreeTypeBuilderFlags to ImGuiFreeTypeLoaderFlags. + If you used runtime imgui_freetype selection rather than the default IMGUI_ENABLE_FREETYPE compile-time option: Renamed/reworked ImFontBuilderIO into ImFontLoader. Renamed ImGuiFreeType::GetBuilderForFreeType() to ImGuiFreeType::GetFontLoader(). + - old: io.Fonts->FontBuilderIO = ImGuiFreeType::GetBuilderForFreeType() + - new: io.Fonts->FontLoader = ImGuiFreeType::GetFontLoader() + - new: io.Fonts->SetFontLoader(ImGuiFreeType::GetFontLoader()) to change dynamically at runtime [from 1.92.1] + - Fonts: (users of custom rectangles, see #8466): Renamed AddCustomRectRegular() to AddCustomRect(). Added GetCustomRect() as a replacement for GetCustomRectByIndex() + CalcCustomRectUV(). + - The output type of GetCustomRect() is now ImFontAtlasRect, which include UV coordinates. X->x, Y->y, Width->w, Height->h. + - old: + const ImFontAtlasCustomRect* r = atlas->GetCustomRectByIndex(custom_rect_id); + ImVec2 uv0, uv1; + atlas->GetCustomRectUV(r, &uv0, &uv1); + ImGui::Image(atlas->TexRef, ImVec2(r->w, r->h), uv0, uv1); + - new; + ImFontAtlasRect r; + atlas->GetCustomRect(custom_rect_id, &r); + ImGui::Image(atlas->TexRef, ImVec2(r.w, r.h), r.uv0, r.uv1); + - We added a redirecting typedef but haven't attempted to magically redirect the field names, as this API is rarely used and the fix is simple. + - Obsoleted AddCustomRectFontGlyph() as the API does not make sense for scalable fonts. Kept existing function which uses the font "default size" (Sources[0]->LegacySize). Added a helper AddCustomRectFontGlyphForSize() which is immediately marked obsolete, but can facilitate transitioning old code. + - Prefer adding a font source (ImFontConfig) using a custom/procedural loader. + - DrawList: Renamed ImDrawList::PushTextureID()/PopTextureID() to PushTexture()/PopTexture(). + - Backends: removed ImGui_ImplXXXX_CreateFontsTexture()/ImGui_ImplXXXX_DestroyFontsTexture() for all backends that had them. They should not be necessary any more. + - 2025/05/23 (1.92.0) - Fonts: changed ImFont::CalcWordWrapPositionA() to ImFont::CalcWordWrapPosition() + - old: const char* ImFont::CalcWordWrapPositionA(float scale, const char* text, ....); + - new: const char* ImFont::CalcWordWrapPosition (float size, const char* text, ....); + The leading 'float scale' parameters was changed to 'float size'. This was necessary as 'scale' is assuming standard font size which is a concept we aim to eliminate in an upcoming update. Kept inline redirection function. + - 2025/05/15 (1.92.0) - TreeNode: renamed ImGuiTreeNodeFlags_NavLeftJumpsBackHere to ImGuiTreeNodeFlags_NavLeftJumpsToParent for clarity. Kept inline redirection enum (will obsolete). + - 2025/05/15 (1.92.0) - Commented out PushAllowKeyboardFocus()/PopAllowKeyboardFocus() which was obsoleted in 1.89.4. Use PushItemFlag(ImGuiItemFlags_NoTabStop, !tab_stop)/PopItemFlag() instead. (#3092) + - 2025/05/15 (1.92.0) - Commented out ImGuiListClipper::ForceDisplayRangeByIndices() which was obsoleted in 1.89.6. Use ImGuiListClipper::IncludeItemsByIndex() instead. + - 2025/03/05 (1.91.9) - BeginMenu(): Internals: reworked mangling of menu windows to use "###Menu_00" etc. instead of "##Menu_00", allowing them to also store the menu name before it. This shouldn't affect code unless directly accessing menu window from their mangled name. + - 2025/04/16 (1.91.9) - Internals: RenderTextEllipsis() function removed the 'float clip_max_x' parameter directly preceding 'float ellipsis_max_x'. Values were identical for a vast majority of users. (#8387) + - 2025/02/27 (1.91.9) - Image(): removed 'tint_col' and 'border_col' parameter from Image() function. Added ImageWithBg() replacement. (#8131, #8238) + - old: void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 tint_col = (1,1,1,1), ImVec4 border_col = (0,0,0,0)); + - new: void Image (ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1)); + - new: void ImageWithBg(ImTextureID tex_id, ImVec2 image_size, ImVec2 uv0 = (0,0), ImVec2 uv1 = (1,1), ImVec4 bg_col = (0,0,0,0), ImVec4 tint_col = (1,1,1,1)); + - TL;DR: 'border_col' had misleading side-effect on layout, 'bg_col' was missing, parameter order couldn't be consistent with ImageButton(). + - new behavior always use ImGuiCol_Border color + style.ImageBorderSize / ImGuiStyleVar_ImageBorderSize. + - old behavior altered border size (and therefore layout) based on border color's alpha, which caused variety of problems + old behavior a fixed 1.0f for border size which was not tweakable. + - kept legacy signature (will obsolete), which mimics the old behavior, but uses Max(1.0f, style.ImageBorderSize) when border_col is specified. + - added ImageWithBg() function which has both 'bg_col' (which was missing) and 'tint_col'. It was impossible to add 'bg_col' to Image() with a parameter order consistent with other functions, so we decided to remove 'tint_col' and introduce ImageWithBg(). + - 2025/02/25 (1.91.9) - internals: fonts: ImFontAtlas::ConfigData[] has been renamed to ImFontAtlas::Sources[]. ImFont::ConfigData[], ConfigDataCount has been renamed to Sources[], SourcesCount. + - 2025/02/06 (1.91.9) - renamed ImFontConfig::GlyphExtraSpacing.x to ImFontConfig::GlyphExtraAdvanceX. + - 2025/01/22 (1.91.8) - removed ImGuiColorEditFlags_AlphaPreview (made value 0): it is now the default behavior. + prior to 1.91.8: alpha was made opaque in the preview by default _unless_ using ImGuiColorEditFlags_AlphaPreview. We now display the preview as transparent by default. You can use ImGuiColorEditFlags_AlphaOpaque to use old behavior. + the new flags (ImGuiColorEditFlags_AlphaOpaque, ImGuiColorEditFlags_AlphaNoBg + existing ImGuiColorEditFlags_AlphaPreviewHalf) may be combined better and allow finer controls: + - 2025/01/14 (1.91.7) - renamed ImGuiTreeNodeFlags_SpanTextWidth to ImGuiTreeNodeFlags_SpanLabelWidth for consistency with other names. Kept redirection enum (will obsolete). (#6937) + - 2024/11/27 (1.91.6) - changed CRC32 table from CRC32-adler to CRC32c polynomial in order to be compatible with the result of SSE 4.2 instructions. + As a result, old .ini data may be partially lost (docking and tables information particularly). + Because some users have crafted and storing .ini data as a way to workaround limitations of the docking API, we are providing a '#define IMGUI_USE_LEGACY_CRC32_ADLER' compile-time option to keep using old CRC32 tables if you cannot afford invalidating old .ini data. + - 2024/11/06 (1.91.5) - commented/obsoleted out pre-1.87 IO system (equivalent to using IMGUI_DISABLE_OBSOLETE_KEYIO or IMGUI_DISABLE_OBSOLETE_FUNCTIONS before) + - io.KeyMap[] and io.KeysDown[] are removed (obsoleted February 2022). + - io.NavInputs[] and ImGuiNavInput are removed (obsoleted July 2022). + - GetKeyIndex() is removed (obsoleted March 2022). The indirection is now unnecessary. + - pre-1.87 backends are not supported: + - backends need to call io.AddKeyEvent(), io.AddMouseEvent() instead of writing to io.KeysDown[], io.MouseDown[] fields. + - backends need to call io.AddKeyAnalogEvent() for gamepad values instead of writing to io.NavInputs[] fields. + - for more reference: + - read 1.87 and 1.88 part of this section or read Changelog for 1.87 and 1.88. + - read https://github.com/ocornut/imgui/issues/4921 + - if you have trouble updating a very old codebase using legacy backend-specific key codes: consider updating to 1.91.4 first, then #define IMGUI_DISABLE_OBSOLETE_KEYIO, then update to latest. + - obsoleted ImGuiKey_COUNT (it is unusually error-prone/misleading since valid keys don't start at 0). probably use ImGuiKey_NamedKey_BEGIN/ImGuiKey_NamedKey_END? + - fonts: removed const qualifiers from most font functions in prevision for upcoming font improvements. + - 2024/10/18 (1.91.4) - renamed ImGuiCol_NavHighlight to ImGuiCol_NavCursor (for consistency with newly exposed and reworked features). Kept inline redirection enum (will obsolete). + - 2024/10/14 (1.91.4) - moved ImGuiConfigFlags_NavEnableSetMousePos to standalone io.ConfigNavMoveSetMousePos bool. + moved ImGuiConfigFlags_NavNoCaptureKeyboard to standalone io.ConfigNavCaptureKeyboard bool (note the inverted value!). + kept legacy names (will obsolete) + code that copies settings once the first time. Dynamically changing the old value won't work. Switch to using the new value! + - 2024/10/10 (1.91.4) - the typedef for ImTextureID now defaults to ImU64 instead of void*. (#1641) + this removes the requirement to redefine it for backends which are e.g. storing descriptor sets or other 64-bits structures when building on 32-bits archs. It therefore simplify various building scripts/helpers. + you may have compile-time issues if you were casting to 'void*' instead of 'ImTextureID' when passing your types to functions taking ImTextureID values, e.g. ImGui::Image(). + in doubt it is almost always better to do an intermediate intptr_t cast, since it allows casting any pointer/integer type without warning: + - May warn: ImGui::Image((void*)MyTextureData, ...); + - May warn: ImGui::Image((void*)(intptr_t)MyTextureData, ...); + - Won't warn: ImGui::Image((ImTextureID)(intptr_t)MyTextureData, ...); + - note that you can always define ImTextureID to be your own high-level structures (with dedicated constructors) if you like. + - 2024/10/03 (1.91.3) - drags: treat v_min==v_max as a valid clamping range when != 0.0f. Zero is a still special value due to legacy reasons, unless using ImGuiSliderFlags_ClampZeroRange. (#7968, #3361, #76) + - drags: extended behavior of ImGuiSliderFlags_AlwaysClamp to include _ClampZeroRange. It considers v_min==v_max==0.0f as a valid clamping range (aka edits not allowed). + although unlikely, it you wish to only clamp on text input but want v_min==v_max==0.0f to mean unclamped drags, you can use _ClampOnInput instead of _AlwaysClamp. (#7968, #3361, #76) + - 2024/09/10 (1.91.2) - internals: using multiple overlaid ButtonBehavior() with same ID will now have io.ConfigDebugHighlightIdConflicts=true feature emit a warning. (#8030) + it was one of the rare case where using same ID is legal. workarounds: (1) use single ButtonBehavior() call with multiple _MouseButton flags, or (2) surround the calls with PushItemFlag(ImGuiItemFlags_AllowDuplicateId, true); ... PopItemFlag() + - 2024/08/23 (1.91.1) - renamed ImGuiChildFlags_Border to ImGuiChildFlags_Borders for consistency. kept inline redirection flag. + - 2024/08/22 (1.91.1) - moved some functions from ImGuiIO to ImGuiPlatformIO structure: + - io.GetClipboardTextFn -> platform_io.Platform_GetClipboardTextFn + changed 'void* user_data' to 'ImGuiContext* ctx'. Pull your user data from platform_io.ClipboardUserData. + - io.SetClipboardTextFn -> platform_io.Platform_SetClipboardTextFn + same as above line. + - io.PlatformOpenInShellFn -> platform_io.Platform_OpenInShellFn (#7660) + - io.PlatformSetImeDataFn -> platform_io.Platform_SetImeDataFn + - io.PlatformLocaleDecimalPoint -> platform_io.Platform_LocaleDecimalPoint (#7389, #6719, #2278) + - access those via GetPlatformIO() instead of GetIO(). + some were introduced very recently and often automatically setup by core library and backends, so for those we are exceptionally not maintaining a legacy redirection symbol. + - commented the old ImageButton() signature obsoleted in 1.89 (~August 2022). As a reminder: + - old ImageButton() before 1.89 used ImTextureId as item id (created issue with e.g. multiple buttons in same scope, transient texture id values, opaque computation of ID) + - new ImageButton() since 1.89 requires an explicit 'const char* str_id' + - old ImageButton() before 1.89 had frame_padding' override argument. + - new ImageButton() since 1.89 always use style.FramePadding, which you can freely override with PushStyleVar()/PopStyleVar(). + - 2024/07/25 (1.91.0) - obsoleted GetContentRegionMax(), GetWindowContentRegionMin() and GetWindowContentRegionMax().

Consider that generally 'GetContentRegionAvail().x' is more useful. + - ImDrawCornerFlags_XXX -> use ImDrawFlags_RoundCornersXXX flags. Read 1.82 Changelog for details + grep commented names in sources. + - commented out runtime support for hardcoded ~0 or 0x01..0x0F rounding flags values for AddRect()/AddRectFilled()/PathRect()/AddImageRounded() -> use ImDrawFlags_RoundCornersXXX flags.

Kept inline redirection function. Sorry! + - 2023/07/12 (1.89.8) - ImDrawData: CmdLists now owned, changed from ImDrawList** to ImVector. Majority of users shouldn't be affected, but you cannot compare to NULL nor reassign manually anymore. Instead use AddDrawList(). (#6406, #4879, #1878) + - 2023/06/28 (1.89.7) - overlapping items: obsoleted 'SetItemAllowOverlap()' (called after item) in favor of calling 'SetNextItemAllowOverlap()' (called before item). 'SetItemAllowOverlap()' didn't and couldn't work reliably since 1.89 (2022-11-15). + - 2023/06/28 (1.89.7) - overlapping items: renamed 'ImGuiTreeNodeFlags_AllowItemOverlap' to 'ImGuiTreeNodeFlags_AllowOverlap', 'ImGuiSelectableFlags_AllowItemOverlap' to 'ImGuiSelectableFlags_AllowOverlap'.

Use ImGuiHoveredFlags_AllowWhenOverlappedByItem to revert to old behavior. + - 2023/06/28 (1.89.7) - overlapping items: Selectable and TreeNode don't allow overlap when active so overlapping widgets won't appear as hovered. While this fixes a common small visual issue, it also means that calling IsItemHovered() after a non-reactive elements - e.g. Text() - overlapping an active one may fail if you don't use IsItemHovered(ImGuiHoveredFlags_AllowWhenBlockedByActiveItem). (#6610) + - 2023/06/20 (1.89.7) - moved io.HoverDelayShort/io.HoverDelayNormal to style.HoverDelayShort/style.HoverDelayNormal.

Kept inline redirection functions (will obsolete). + - 2023/03/09 (1.89.4) - tooltips: Added 'bool' return value to BeginTooltip() for API consistency. Please only submit contents and call EndTooltip() if BeginTooltip() returns true. In reality the function will _currently_ always return true, but further changes down the line may change this, best to clarify API sooner. + - 2023/02/15 (1.89.4) - moved the optional "courtesy maths operators" implementation from imgui_internal.h in imgui.h. + Even though we encourage using your own maths types and operators by setting up IM_VEC2_CLASS_EXTRA, + it has been frequently requested by people to use our own. We had an opt-in define which was + previously fulfilled in imgui_internal.h. It is now fulfilled in imgui.h.

(#6146) This is in prevision for the future release of SDL3. + - 2022/10/26 (1.89) - commented out redirecting OpenPopupContextItem() which was briefly the name of OpenPopupOnItemClick() from 1.77 to 1.79. + - 2022/10/12 (1.89) - removed runtime patching of invalid "%f"/"%0.f" format strings for DragInt()/SliderInt().

Please open an issue if you think you really need this function. + - 2021/08/23 (1.85) - removed GetWindowContentRegionWidth() function. keep inline redirection helper. can use 'GetWindowContentRegionMax().x - GetWindowContentRegionMin().x' instead for generally 'GetContentRegionAvail().x' is more useful. + - 2021/07/26 (1.84) - commented out redirecting functions/enums names that were marked obsolete in 1.67 and 1.69 (March 2019): + - ImGui::GetOverlayDrawList() -> use ImGui::GetForegroundDrawList() + - ImFont::GlyphRangesBuilder -> use ImFontGlyphRangesBuilder + - 2021/05/19 (1.83) - backends: obsoleted direct access to ImDrawCmd::TextureId in favor of calling ImDrawCmd::GetTexID(). + - if you are using official backends from the source tree: you have nothing to do. + - if you have copied old backend code or using your own: change access to draw_cmd->TextureId to draw_cmd->GetTexID(). + - 2021/03/12 (1.82) - upgraded ImDrawList::AddRect(), AddRectFilled(), PathRect() to use ImDrawFlags instead of ImDrawCornersFlags. + - ImDrawCornerFlags_TopLeft -> use ImDrawFlags_RoundCornersTopLeft + - ImDrawCornerFlags_BotRight -> use ImDrawFlags_RoundCornersBottomRight + - ImDrawCornerFlags_None -> use ImDrawFlags_RoundCornersNone etc. + flags now sanely defaults to 0 instead of 0x0F, consistent with all other flags in the API. + breaking: the default with rounding > 0.0f is now "round all corners" vs old implicit "round no corners": + - rounding == 0.0f + flags == 0 --> meant no rounding --> unchanged (common use) + - rounding > 0.0f + flags != 0 --> meant rounding --> unchanged (common use) + - rounding == 0.0f + flags != 0 --> meant no rounding --> unchanged (unlikely use) + - rounding > 0.0f + flags == 0 --> meant no rounding --> BREAKING (unlikely use): will now round all corners --> use ImDrawFlags_RoundCornersNone or rounding == 0.0f. + this ONLY matters for hard coded use of 0 + rounding > 0.0f. Use of named ImDrawFlags_RoundCornersNone (new) or ImDrawCornerFlags_None (old) are ok. + the old ImDrawCornersFlags used awkward default values of ~0 or 0xF (4 lower bits set) to signify "round all corners" and we sometimes encouraged using them as shortcuts. + legacy path still support use of hard coded ~0 or any value from 0x1 or 0xF. They will behave the same with legacy paths enabled (will assert otherwise). + - 2021/03/11 (1.82) - removed redirecting functions/enums names that were marked obsolete in 1.66 (September 2018): + - ImGui::SetScrollHere() -> use ImGui::SetScrollHereY() + - 2021/03/11 (1.82) - clarified that ImDrawList::PathArcTo(), ImDrawList::PathArcToFast() won't render with radius < 0.0f. Previously it sorts of accidentally worked but would generally lead to counter-clockwise paths and have an effect on anti-aliasing. + - 2021/03/10 (1.82) - upgraded ImDrawList::AddPolyline() and PathStroke() "bool closed" parameter to "ImDrawFlags flags". The matching ImDrawFlags_Closed value is guaranteed to always stay == 1 in the future. + - 2021/02/22 (1.82) - (*undone in 1.84*) win32+mingw: Re-enabled IME functions by default even under MinGW. In July 2016, issue #738 had me incorrectly disable those default functions for MinGW. MinGW users should: either link with -limm32, either set their imconfig file with '#define IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS'. + - 2021/02/17 (1.82) - renamed rarely used style.CircleSegmentMaxError (old default = 1.60f) to style.CircleTessellationMaxError (new default = 0.30f) as the meaning of the value changed. + - 2021/02/03 (1.81) - renamed ListBoxHeader(const char* label, ImVec2 size) to BeginListBox(). Kept inline redirection function (will obsolete). + - removed ListBoxHeader(const char* label, int items_count, int height_in_items = -1) in favor of specifying size. Kept inline redirection function (will obsolete). + - renamed ListBoxFooter() to EndListBox(). Kept inline redirection function (will obsolete). + - 2021/01/26 (1.81) - removed ImGuiFreeType::BuildFontAtlas(). Kept inline redirection function. Prefer using '#define IMGUI_ENABLE_FREETYPE', but there's a runtime selection path available too. The shared extra flags parameters (very rarely used) are now stored in ImFontAtlas::FontBuilderFlags. + - renamed ImFontConfig::RasterizerFlags (used by FreeType) to ImFontConfig::FontBuilderFlags. + - renamed ImGuiFreeType::XXX flags to ImGuiFreeTypeBuilderFlags_XXX for consistency with other API. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.63 (August 2018): + - ImGui::IsItemDeactivatedAfterChange() -> use ImGui::IsItemDeactivatedAfterEdit(). + - ImGuiCol_ModalWindowDarkening -> use ImGuiCol_ModalWindowDimBg + - ImGuiInputTextCallback -> use ImGuiTextEditCallback + - ImGuiInputTextCallbackData -> use ImGuiTextEditCallbackData + - 2020/12/21 (1.80) - renamed ImDrawList::AddBezierCurve() to AddBezierCubic(), and PathBezierCurveTo() to PathBezierCubicCurveTo(). Kept inline redirection function (will obsolete). + - 2020/12/04 (1.80) - added imgui_tables.cpp file! Manually constructed project files will need the new file added! + - 2020/11/18 (1.80) - renamed undocumented/internals ImGuiColumnsFlags_* to ImGuiOldColumnFlags_* in prevision of incoming Tables API. + - 2020/11/03 (1.80) - renamed io.ConfigWindowsMemoryCompactTimer to io.ConfigMemoryCompactTimer as the feature will apply to other data structures + - 2020/10/14 (1.80) - backends: moved all backends files (imgui_impl_XXXX.cpp, imgui_impl_XXXX.h) from examples/ to backends/. + - 2020/10/12 (1.80) - removed redirecting functions/enums that were marked obsolete in 1.60 (April 2018): + - io.RenderDrawListsFn pointer -> use ImGui::GetDrawData() value and call the render function of your backend + - ImGui::IsAnyWindowFocused() -> use ImGui::IsWindowFocused(ImGuiFocusedFlags_AnyWindow) + - ImGui::IsAnyWindowHovered() -> use ImGui::IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + - ImGuiStyleVar_Count_ -> use ImGuiStyleVar_COUNT + - ImGuiMouseCursor_Count_ -> use ImGuiMouseCursor_COUNT + - removed redirecting functions names that were marked obsolete in 1.61 (May 2018): + - InputFloat (... int decimal_precision ...) -> use InputFloat (... const char* format ...) with format = "%.Xf" where X is your value for decimal_precision. + - same for InputFloat2()/InputFloat3()/InputFloat4() variants taking a `int decimal_precision` parameter. + - 2020/10/05 (1.79) - removed ImGuiListClipper: Renamed constructor parameters which created an ambiguous alternative to using the ImGuiListClipper::Begin() function, with misleading edge cases (note: imgui_memory_editor <0.40 from imgui_club/ used this old clipper API. Update your copy if needed). + - 2020/09/25 (1.79) - renamed ImGuiSliderFlags_ClampOnInput to ImGuiSliderFlags_AlwaysClamp. Kept redirection enum (will obsolete sooner because previous name was added recently). + - 2020/09/25 (1.79) - renamed style.TabMinWidthForUnselectedCloseButton to style.TabMinWidthForCloseButton. + - 2020/09/21 (1.79) - renamed OpenPopupContextItem() back to OpenPopupOnItemClick(), reverting the change from 1.77. For varieties of reason this is more self-explanatory. + - 2020/09/21 (1.79) - removed return value from OpenPopupOnItemClick() - returned true on mouse release on an item - because it is inconsistent with other popup APIs and makes others misleading. It's also and unnecessary: you can use IsWindowAppearing() after BeginPopup() for a similar result. + - 2020/09/17 (1.79) - removed ImFont::DisplayOffset in favor of ImFontConfig::GlyphOffset. DisplayOffset was applied after scaling and not very meaningful/useful outside of being needed by the default ProggyClean font. If you scaled this value after calling AddFontDefault(), this is now done automatically. It was also getting in the way of better font scaling, so let's get rid of it now! + - 2020/08/17 (1.78) - obsoleted use of the trailing 'float power=1.0f' parameter for DragFloat(), DragFloat2(), DragFloat3(), DragFloat4(), DragFloatRange2(), DragScalar(), DragScalarN(), SliderFloat(), SliderFloat2(), SliderFloat3(), SliderFloat4(), SliderScalar(), SliderScalarN(), VSliderFloat() and VSliderScalar(). + replaced the 'float power=1.0f' argument with integer-based flags defaulting to 0 (as with all our flags). + worked out a backward-compatibility scheme so hopefully most C++ codebase should not be affected. in short, when calling those functions: + - if you omitted the 'power' parameter (likely!), you are not affected. + - if you set the 'power' parameter to 1.0f (same as previous default value): 1/ your compiler may warn on float>int conversion, 2/ everything else will work. 3/ you can replace the 1.0f value with 0 to fix the warning, and be technically correct. + - if you set the 'power' parameter to >1.0f (to enable non-linear editing): 1/ your compiler may warn on float>int conversion, 2/ code will assert at runtime, 3/ in case asserts are disabled, the code will not crash and enable the _Logarithmic flag. 4/ you can replace the >1.0f value with ImGuiSliderFlags_Logarithmic to fix the warning/assert and get a _similar_ effect as previous uses of power >1.0f. + see https://github.com/ocornut/imgui/issues/3361 for all details. + kept inline redirection functions (will obsolete) apart for: DragFloatRange2(), VSliderFloat(), VSliderScalar(). For those three the 'float power=1.0f' version was removed directly as they were most unlikely ever used. + for shared code, you can version check at compile-time with `#if IMGUI_VERSION_NUM >= 17704`. + - obsoleted use of v_min > v_max in DragInt, DragFloat, DragScalar to lock edits (introduced in 1.73, was not demoed nor documented very), will be replaced by a more generic ReadOnly feature. You may use the ImGuiSliderFlags_ReadOnly internal flag in the meantime. + - 2020/06/23 (1.77) - removed BeginPopupContextWindow(const char*, int mouse_button, bool also_over_items) in favor of BeginPopupContextWindow(const char*, ImGuiPopupFlags flags) with ImGuiPopupFlags_NoOverItems. + - 2020/06/15 (1.77) - renamed OpenPopupOnItemClick() to OpenPopupContextItem(). Kept inline redirection function (will obsolete). [NOTE: THIS WAS REVERTED IN 1.79] + - 2020/06/15 (1.77) - removed CalcItemRectClosestPoint() entry point which was made obsolete and asserting in December 2017. + - 2020/04/23 (1.77) - removed unnecessary ID (first arg) of ImFontAtlas::AddCustomRectRegular(). + - 2020/01/22 (1.75) - ImDrawList::AddCircle()/AddCircleFilled() functions don't accept negative radius any more. + - 2019/12/17 (1.75) - [undid this change in 1.76] made Columns() limited to 64 columns by asserting above that limit. While the current code technically supports it, future code may not so we're putting the restriction ahead. + - 2019/12/13 (1.75) - [imgui_internal.h] changed ImRect() default constructor initializes all fields to 0.0f instead of (FLT_MAX,FLT_MAX,-FLT_MAX,-FLT_MAX). If you used ImRect::Add() to create bounding boxes by adding multiple points into it, you may need to fix your initial value. + - 2019/12/08 (1.75) - removed redirecting functions/enums that were marked obsolete in 1.53 (December 2017): + - ShowTestWindow() -> use ShowDemoWindow() + - IsRootWindowFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootWindow) + - IsRootWindowOrAnyChildFocused() -> use IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows) + - SetNextWindowContentWidth(w) -> use SetNextWindowContentSize(ImVec2(w, 0.0f)) + - GetItemsLineHeightWithSpacing() -> use GetFrameHeightWithSpacing() + - ImGuiCol_ChildWindowBg -> use ImGuiCol_ChildBg + - ImGuiStyleVar_ChildWindowRounding -> use ImGuiStyleVar_ChildRounding + - ImGuiTreeNodeFlags_AllowOverlapMode -> use ImGuiTreeNodeFlags_AllowItemOverlap + - IMGUI_DISABLE_TEST_WINDOWS -> use IMGUI_DISABLE_DEMO_WINDOWS + - 2019/12/08 (1.75) - obsoleted calling ImDrawList::PrimReserve() with a negative count (which was vaguely documented and rarely if ever used). Instead, we added an explicit PrimUnreserve() API. + - 2019/12/06 (1.75) - removed implicit default parameter to IsMouseDragging(int button = 0) to be consistent with other mouse functions (none of the other functions have it). + - 2019/11/21 (1.74) - ImFontAtlas::AddCustomRectRegular() now requires an ID larger than 0x110000 (instead of 0x10000) to conform with supporting Unicode planes 1-16 in a future update. ID below 0x110000 will now assert. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_FORMAT_STRING_FUNCTIONS to IMGUI_DISABLE_DEFAULT_FORMAT_FUNCTIONS for consistency. + - 2019/11/19 (1.74) - renamed IMGUI_DISABLE_MATH_FUNCTIONS to IMGUI_DISABLE_DEFAULT_MATH_FUNCTIONS for consistency. + - 2019/10/22 (1.74) - removed redirecting functions/enums that were marked obsolete in 1.52 (October 2017): + - Begin() [old 5 args version] -> use Begin() [3 args], use SetNextWindowSize() SetNextWindowBgAlpha() if needed + - IsRootWindowOrAnyChildHovered() -> use IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows) + - AlignFirstTextHeightToWidgets() -> use AlignTextToFramePadding() + - SetNextWindowPosCenter() -> use SetNextWindowPos() with a pivot of (0.5f, 0.5f) + - ImFont::Glyph -> use ImFontGlyph + - 2019/10/14 (1.74) - inputs: Fixed a miscalculation in the keyboard/mouse "typematic" repeat delay/rate calculation, used by keys and e.g. repeating mouse buttons as well as the GetKeyPressedAmount() function. + if you were using a non-default value for io.KeyRepeatRate (previous default was 0.250), you can add +io.KeyRepeatDelay to it to compensate for the fix. + The function was triggering on: 0.0 and (delay+rate*N) where (N>=1). Fixed formula responds to (N>=0). Effectively it made io.KeyRepeatRate behave like it was set to (io.KeyRepeatRate + io.KeyRepeatDelay). + If you never altered io.KeyRepeatRate nor used GetKeyPressedAmount() this won't affect you. + - 2019/07/15 (1.72) - removed TreeAdvanceToLabelPos() which is rarely used and only does SetCursorPosX(GetCursorPosX() + GetTreeNodeToLabelSpacing()). Kept redirection function (will obsolete). + - 2019/07/12 (1.72) - renamed ImFontAtlas::CustomRect to ImFontAtlasCustomRect. Kept redirection typedef (will obsolete). + - 2019/06/14 (1.72) - removed redirecting functions/enums names that were marked obsolete in 1.51 (June 2017): ImGuiCol_Column*, ImGuiSetCond_*, IsItemHoveredRect(), IsPosHoveringAnyWindow(), IsMouseHoveringAnyWindow(), IsMouseHoveringWindow(), IMGUI_ONCE_UPON_A_FRAME. Grep this log for details and new names, or see how they were implemented until 1.71. + - 2019/06/07 (1.71) - rendering of child window outer decorations (bg color, border, scrollbars) is now performed as part of the parent window. If you have + overlapping child windows in a same parent, and relied on their relative z-order to be mapped to their submission order, this will affect your rendering. + This optimization is disabled if the parent window has no visual output, because it appears to be the most common situation leading to the creation of overlapping child windows. + Please reach out if you are affected. + - 2019/05/13 (1.71) - renamed SetNextTreeNodeOpen() to SetNextItemOpen(). Kept inline redirection function (will obsolete). + - 2019/05/11 (1.71) - changed io.AddInputCharacter(unsigned short c) signature to io.AddInputCharacter(unsigned int c). + - 2019/04/29 (1.70) - improved ImDrawList thick strokes (>1.0f) preserving correct thickness up to 90 degrees angles (e.g. rectangles). If you have custom rendering using thick lines, they will appear thicker now. + - 2019/04/29 (1.70) - removed GetContentRegionAvailWidth(), use GetContentRegionAvail().x instead. Kept inline redirection function (will obsolete). + - 2019/03/04 (1.69) - renamed GetOverlayDrawList() to GetForegroundDrawList(). Kept redirection function (will obsolete). + - 2019/02/26 (1.69) - renamed ImGuiColorEditFlags_RGB/ImGuiColorEditFlags_HSV/ImGuiColorEditFlags_HEX to ImGuiColorEditFlags_DisplayRGB/ImGuiColorEditFlags_DisplayHSV/ImGuiColorEditFlags_DisplayHex. Kept redirection enums (will obsolete). + - 2019/02/14 (1.68) - made it illegal/assert when io.DisplayTime == 0.0f (with an exception for the first frame). If for some reason your time step calculation gives you a zero value, replace it with an arbitrarily small value! + - 2019/02/01 (1.68) - removed io.DisplayVisibleMin/DisplayVisibleMax (which were marked obsolete and removed from viewport/docking branch already). + - 2019/01/06 (1.67) - renamed io.InputCharacters[], marked internal as was always intended. Please don't access directly, and use AddInputCharacter() instead! + - 2019/01/06 (1.67) - renamed ImFontAtlas::GlyphRangesBuilder to ImFontGlyphRangesBuilder. Kept redirection typedef (will obsolete). + - 2018/12/20 (1.67) - made it illegal to call Begin("") with an empty string. This somehow half-worked before but had various undesirable side-effects. + - 2018/12/10 (1.67) - renamed io.ConfigResizeWindowsFromEdges to io.ConfigWindowsResizeFromEdges as we are doing a large pass on configuration flags. + - 2018/10/12 (1.66) - renamed misc/stl/imgui_stl.* to misc/cpp/imgui_stdlib.* in prevision for other C++ helper files. + - 2018/09/28 (1.66) - renamed SetScrollHere() to SetScrollHereY(). Kept redirection function (will obsolete). + - 2018/09/06 (1.65) - renamed stb_truetype.h to imstb_truetype.h, stb_textedit.h to imstb_textedit.h, and stb_rect_pack.h to imstb_rectpack.h. + If you were conveniently using the imgui copy of those STB headers in your project you will have to update your include paths. + - 2018/09/05 (1.65) - renamed io.OptCursorBlink/io.ConfigCursorBlink to io.ConfigInputTextCursorBlink. (#1427) + - 2018/08/31 (1.64) - added imgui_widgets.cpp file, extracted and moved widgets code out of imgui.cpp into imgui_widgets.cpp. Re-ordered some of the code remaining in imgui.cpp. + NONE OF THE FUNCTIONS HAVE CHANGED. THE CODE IS SEMANTICALLY 100% IDENTICAL, BUT _EVERY_ FUNCTION HAS BEEN MOVED. + Because of this, any local modifications to imgui.cpp will likely conflict when you update. Read docs/CHANGELOG.txt for suggestions. + - 2018/08/22 (1.63) - renamed IsItemDeactivatedAfterChange() to IsItemDeactivatedAfterEdit() for consistency with new IsItemEdited() API. Kept redirection function (will obsolete soonish as IsItemDeactivatedAfterChange() is very recent). + - 2018/08/21 (1.63) - renamed ImGuiTextEditCallback to ImGuiInputTextCallback, ImGuiTextEditCallbackData to ImGuiInputTextCallbackData for consistency. Kept redirection types (will obsolete). + - 2018/08/21 (1.63) - removed ImGuiInputTextCallbackData::ReadOnly since it is a duplication of (ImGuiInputTextCallbackData::Flags & ImGuiInputTextFlags_ReadOnly). + - 2018/08/01 (1.63) - removed per-window ImGuiWindowFlags_ResizeFromAnySide beta flag in favor of a global io.ConfigResizeWindowsFromEdges [update 1.67 renamed to ConfigWindowsResizeFromEdges] to enable the feature. + - 2018/08/01 (1.63) - renamed io.OptCursorBlink to io.ConfigCursorBlink [-> io.ConfigInputTextCursorBlink in 1.65], io.OptMacOSXBehaviors to ConfigMacOSXBehaviors for consistency. + - 2018/07/22 (1.63) - changed ImGui::GetTime() return value from float to double to avoid accumulating floating point imprecisions over time. + - 2018/07/08 (1.63) - style: renamed ImGuiCol_ModalWindowDarkening to ImGuiCol_ModalWindowDimBg for consistency with other features. Kept redirection enum (will obsolete). + - 2018/06/08 (1.62) - examples: the imgui_impl_XXX files have been split to separate platform (Win32, GLFW, SDL2, etc.) from renderer (DX11, OpenGL, Vulkan, etc.). + old backends will still work as is, however prefer using the separated backends as they will be updated to support multi-viewports. + when adopting new backends follow the main.cpp code of your preferred examples/ folder to know which functions to call. + in particular, note that old backends called ImGui::NewFrame() at the end of their ImGui_ImplXXXX_NewFrame() function. + - 2018/06/06 (1.62) - renamed GetGlyphRangesChinese() to GetGlyphRangesChineseFull() to distinguish other variants and discourage using the full set. + - 2018/06/06 (1.62) - TreeNodeEx()/TreeNodeBehavior(): the ImGuiTreeNodeFlags_CollapsingHeader helper now include the ImGuiTreeNodeFlags_NoTreePushOnOpen flag. See Changelog for details. + - 2018/05/03 (1.61) - DragInt(): the default compile-time format string has been changed from "%.0f" to "%d", as we are not using integers internally any more. + If you used DragInt() with custom format strings, make sure you change them to use %d or an integer-compatible format. + To honor backward-compatibility, the DragInt() code will currently parse and modify format strings to replace %*f with %d, giving time to users to upgrade their code. + If you have IMGUI_DISABLE_OBSOLETE_FUNCTIONS enabled, the code will instead assert! You may run a reg-exp search on your codebase for e.g. "DragInt.*%f" to help you find them. + - 2018/04/28 (1.61) - obsoleted InputFloat() functions taking an optional "int decimal_precision" in favor of an equivalent and more flexible "const char* format", + consistent with other functions. Kept redirection functions (will obsolete). + - 2018/04/09 (1.61) - IM_DELETE() helper function added in 1.60 doesn't clear the input _pointer_ reference, more consistent with expectation and allows passing r-value. + - 2018/03/20 (1.60) - renamed io.WantMoveMouse to io.WantSetMousePos for consistency and ease of understanding (was added in 1.52, _not_ used by core and only honored by some backend ahead of merging the Nav branch). + - 2018/03/12 (1.60) - removed ImGuiCol_CloseButton, ImGuiCol_CloseButtonActive, ImGuiCol_CloseButtonHovered as the closing cross uses regular button colors now. + - 2018/03/08 (1.60) - changed ImFont::DisplayOffset.y to default to 0 instead of +1. Fixed rounding of Ascent/Descent to match TrueType renderer. If you were adding or subtracting to ImFont::DisplayOffset check if your fonts are correctly aligned vertically. + - 2018/03/03 (1.60) - renamed ImGuiStyleVar_Count_ to ImGuiStyleVar_COUNT and ImGuiMouseCursor_Count_ to ImGuiMouseCursor_COUNT for consistency with other public enums. + - 2018/02/18 (1.60) - BeginDragDropSource(): temporarily removed the optional mouse_button=0 parameter because it is not really usable in many situations at the moment. + - 2018/02/16 (1.60) - obsoleted the io.RenderDrawListsFn callback, you can call your graphics engine render function after ImGui::Render(). Use ImGui::GetDrawData() to retrieve the ImDrawData* to display. + - 2018/02/07 (1.60) - reorganized context handling to be more explicit, + - YOU NOW NEED TO CALL ImGui::CreateContext() AT THE BEGINNING OF YOUR APP, AND CALL ImGui::DestroyContext() AT THE END. + - removed Shutdown() function, as DestroyContext() serve this purpose. + - you may pass a ImFontAtlas* pointer to CreateContext() to share a font atlas between contexts. Otherwise CreateContext() will create its own font atlas instance. + - removed allocator parameters from CreateContext(), they are now setup with SetAllocatorFunctions(), and shared by all contexts. + - removed the default global context and font atlas instance, which were confusing for users of DLL reloading and users of multiple contexts. + - 2018/01/31 (1.60) - moved sample TTF files from extra_fonts/ to misc/fonts/. If you loaded files directly from the imgui repo you may need to update your paths. + - 2018/01/11 (1.60) - obsoleted IsAnyWindowHovered() in favor of IsWindowHovered(ImGuiHoveredFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/11 (1.60) - obsoleted IsAnyWindowFocused() in favor of IsWindowFocused(ImGuiFocusedFlags_AnyWindow). Kept redirection function (will obsolete). + - 2018/01/03 (1.60) - renamed ImGuiSizeConstraintCallback to ImGuiSizeCallback, ImGuiSizeConstraintCallbackData to ImGuiSizeCallbackData. + - 2017/12/29 (1.60) - removed CalcItemRectClosestPoint() which was weird and not really used by anyone except demo code. If you need it it's easy to replicate on your side. + - 2017/12/24 (1.53) - renamed the emblematic ShowTestWindow() function to ShowDemoWindow(). Kept redirection function (will obsolete). + - 2017/12/21 (1.53) - ImDrawList: renamed style.AntiAliasedShapes to style.AntiAliasedFill for consistency and as a way to explicitly break code that manipulate those flag at runtime. You can now manipulate ImDrawList::Flags + - 2017/12/21 (1.53) - ImDrawList: removed 'bool anti_aliased = true' final parameter of ImDrawList::AddPolyline() and ImDrawList::AddConvexPolyFilled(). Prefer manipulating ImDrawList::Flags if you need to toggle them during the frame. + - 2017/12/14 (1.53) - using the ImGuiWindowFlags_NoScrollWithMouse flag on a child window forwards the mouse wheel event to the parent window, unless either ImGuiWindowFlags_NoInputs or ImGuiWindowFlags_NoScrollbar are also set. + - 2017/12/13 (1.53) - renamed GetItemsLineHeightWithSpacing() to GetFrameHeightWithSpacing(). Kept redirection function (will obsolete). + - 2017/12/13 (1.53) - obsoleted IsRootWindowFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootWindow). Kept redirection function (will obsolete). + - obsoleted IsRootWindowOrAnyChildFocused() in favor of using IsWindowFocused(ImGuiFocusedFlags_RootAndChildWindows). Kept redirection function (will obsolete). + - 2017/12/12 (1.53) - renamed ImGuiTreeNodeFlags_AllowOverlapMode to ImGuiTreeNodeFlags_AllowItemOverlap. Kept redirection enum (will obsolete). + - 2017/12/10 (1.53) - removed SetNextWindowContentWidth(), prefer using SetNextWindowContentSize(). Kept redirection function (will obsolete). + - 2017/11/27 (1.53) - renamed ImGuiTextBuffer::append() helper to appendf(), appendv() to appendfv(). If you copied the 'Log' demo in your code, it uses appendv() so that needs to be renamed. + - 2017/11/18 (1.53) - Style, Begin: removed ImGuiWindowFlags_ShowBorders window flag. Borders are now fully set up in the ImGuiStyle structure (see e.g. style.FrameBorderSize, style.WindowBorderSize). Use ImGui::ShowStyleEditor() to look them up. + Please note that the style system will keep evolving (hopefully stabilizing in Q1 2018), and so custom styles will probably subtly break over time. It is recommended you use the StyleColorsClassic(), StyleColorsDark(), StyleColorsLight() functions. + - 2017/11/18 (1.53) - Style: removed ImGuiCol_ComboBg in favor of combo boxes using ImGuiCol_PopupBg for consistency. + - 2017/11/18 (1.53) - Style: renamed ImGuiCol_ChildWindowBg to ImGuiCol_ChildBg. + - 2017/11/18 (1.53) - Style: renamed style.ChildWindowRounding to style.ChildRounding, ImGuiStyleVar_ChildWindowRounding to ImGuiStyleVar_ChildRounding. + - 2017/11/02 (1.53) - obsoleted IsRootWindowOrAnyChildHovered() in favor of using IsWindowHovered(ImGuiHoveredFlags_RootAndChildWindows); + - 2017/10/24 (1.52) - renamed IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCS to IMGUI_DISABLE_WIN32_DEFAULT_CLIPBOARD_FUNCTIONS/IMGUI_DISABLE_WIN32_DEFAULT_IME_FUNCTIONS for consistency. + - 2017/10/20 (1.52) - changed IsWindowHovered() default parameters behavior to return false if an item is active in another window (e.g. click-dragging item from another window to this window). You can use the newly introduced IsWindowHovered() flags to requests this specific behavior if you need it. + - 2017/10/20 (1.52) - marked IsItemHoveredRect()/IsMouseHoveringWindow() as obsolete, in favor of using the newly introduced flags for IsItemHovered() and IsWindowHovered(). See https://github.com/ocornut/imgui/issues/1382 for details. + removed the IsItemRectHovered()/IsWindowRectHovered() names introduced in 1.51 since they were merely more consistent names for the two functions we are now obsoleting. + IsItemHoveredRect() --> IsItemHovered(ImGuiHoveredFlags_RectOnly) + IsMouseHoveringAnyWindow() --> IsWindowHovered(ImGuiHoveredFlags_AnyWindow) + IsMouseHoveringWindow() --> IsWindowHovered(ImGuiHoveredFlags_AllowWhenBlockedByPopup | ImGuiHoveredFlags_AllowWhenBlockedByActiveItem) [weird, old behavior] + - 2017/10/17 (1.52) - marked the old 5-parameters version of Begin() as obsolete (still available). Use SetNextWindowSize()+Begin() instead! + - 2017/10/11 (1.52) - renamed AlignFirstTextHeightToWidgets() to AlignTextToFramePadding(). Kept inline redirection function (will obsolete). + - 2017/09/26 (1.52) - renamed ImFont::Glyph to ImFontGlyph. Kept redirection typedef (will obsolete). + - 2017/09/25 (1.52) - removed SetNextWindowPosCenter() because SetNextWindowPos() now has the optional pivot information to do the same and more. Kept redirection function (will obsolete). + - 2017/08/25 (1.52) - io.MousePos needs to be set to ImVec2(-FLT_MAX,-FLT_MAX) when mouse is unavailable/missing. Previously ImVec2(-1,-1) was enough but we now accept negative mouse coordinates. In your backend if you need to support unavailable mouse, make sure to replace "io.MousePos = ImVec2(-1,-1)" with "io.MousePos = ImVec2(-FLT_MAX,-FLT_MAX)". + - 2017/08/22 (1.51) - renamed IsItemHoveredRect() to IsItemRectHovered(). Kept inline redirection function (will obsolete). -> (1.52) use IsItemHovered(ImGuiHoveredFlags_RectOnly)! + - renamed IsMouseHoveringAnyWindow() to IsAnyWindowHovered() for consistency. Kept inline redirection function (will obsolete). + - renamed IsMouseHoveringWindow() to IsWindowRectHovered() for consistency. Kept inline redirection function (will obsolete). + - 2017/08/20 (1.51) - renamed GetStyleColName() to GetStyleColorName() for consistency. + - 2017/08/20 (1.51) - added PushStyleColor(ImGuiCol idx, ImU32 col) overload, which _might_ cause an "ambiguous call" compilation error if you are using ImColor() with implicit cast. Cast to ImU32 or ImVec4 explicitly to fix. + - 2017/08/15 (1.51) - marked the weird IMGUI_ONCE_UPON_A_FRAME helper macro as obsolete. prefer using the more explicit ImGuiOnceUponAFrame type. + - 2017/08/15 (1.51) - changed parameter order for BeginPopupContextWindow() from (const char*,int buttons,bool also_over_items) to (const char*,int buttons,bool also_over_items). Note that most calls relied on default parameters completely. + - 2017/08/13 (1.51) - renamed ImGuiCol_Column to ImGuiCol_Separator, ImGuiCol_ColumnHovered to ImGuiCol_SeparatorHovered, ImGuiCol_ColumnActive to ImGuiCol_SeparatorActive. Kept redirection enums (will obsolete). + - 2017/08/11 (1.51) - renamed ImGuiSetCond_Always to ImGuiCond_Always, ImGuiSetCond_Once to ImGuiCond_Once, ImGuiSetCond_FirstUseEver to ImGuiCond_FirstUseEver, ImGuiSetCond_Appearing to ImGuiCond_Appearing. Kept redirection enums (will obsolete). + - 2017/08/09 (1.51) - removed ValueColor() helpers, they are equivalent to calling Text(label) + SameLine() + ColorButton(). + - 2017/08/08 (1.51) - removed ColorEditMode() and ImGuiColorEditMode in favor of ImGuiColorEditFlags and parameters to the various Color*() functions. The SetColorEditOptions() allows to initialize default but the user can still change them with right-click context menu. + - changed prototype of 'ColorEdit4(const char* label, float col[4], bool show_alpha = true)' to 'ColorEdit4(const char* label, float col[4], ImGuiColorEditFlags flags = 0)', where passing flags = 0x01 is a safe no-op (hello dodgy backward compatibility!). - check and run the demo window, under "Color/Picker Widgets", to understand the various new options. + - changed prototype of rarely used 'ColorButton(ImVec4 col, bool small_height = false, bool outline_border = true)' to 'ColorButton(const char* desc_id, ImVec4 col, ImGuiColorEditFlags flags = 0, ImVec2 size = ImVec2(0, 0))' + - 2017/07/20 (1.51) - removed IsPosHoveringAnyWindow(ImVec2), which was partly broken and misleading. ASSERT + redirect user to io.WantCaptureMouse + - 2017/05/26 (1.50) - removed ImFontConfig::MergeGlyphCenterV in favor of a more multipurpose ImFontConfig::GlyphOffset. + - 2017/05/01 (1.50) - renamed ImDrawList::PathFill() (rarely used directly) to ImDrawList::PathFillConvex() for clarity. + - 2016/11/06 (1.50) - BeginChild(const char*) now applies the stack id to the provided label, consistently with other functions as it should always have been. It shouldn't affect you unless (extremely unlikely) you were appending multiple times to a same child from different locations of the stack id. If that's the case, generate an id with GetID() and use it instead of passing string to BeginChild(). + - 2016/10/15 (1.50) - avoid 'void* user_data' parameter to io.SetClipboardTextFn/io.GetClipboardTextFn pointers. We pass io.ClipboardUserData to it. + - 2016/09/25 (1.50) - style.WindowTitleAlign is now a ImVec2 (ImGuiAlign enum was removed). set to (0.5f,0.5f) for horizontal+vertical centering, (0.0f,0.0f) for upper-left, etc. + - 2016/07/30 (1.50) - SameLine(x) with x>0.0f is now relative to left of column/group if any, and not always to left of window. This was sort of always the intent and hopefully, breakage should be minimal. + - 2016/05/12 (1.49) - title bar (using ImGuiCol_TitleBg/ImGuiCol_TitleBgActive colors) isn't rendered over a window background (ImGuiCol_WindowBg color) anymore. + If your TitleBg/TitleBgActive alpha was 1.0f or you are using the default theme it will not affect you, otherwise if <1.0f you need to tweak your custom theme to readjust for the fact that we don't draw a WindowBg background behind the title bar. + This helper function will convert an old TitleBg/TitleBgActive color into a new one with the same visual output, given the OLD color and the OLD WindowBg color: + ImVec4 ConvertTitleBgCol(const ImVec4& win_bg_col, const ImVec4& title_bg_col) { float new_a = 1.0f - ((1.0f - win_bg_col.w) * (1.0f - title_bg_col.w)), k = title_bg_col.w / new_a; return ImVec4((win_bg_col.x * win_bg_col.w + title_bg_col.x) * k, (win_bg_col.y * win_bg_col.w + title_bg_col.y) * k, (win_bg_col.z * win_bg_col.w + title_bg_col.z) * k, new_a); } + If this is confusing, pick the RGB value from title bar from an old screenshot and apply this as TitleBg/TitleBgActive. Or you may just create TitleBgActive from a tweaked TitleBg color. + - 2016/05/07 (1.49) - removed confusing set of GetInternalState(), GetInternalStateSize(), SetInternalState() functions. Now using CreateContext(), DestroyContext(), GetCurrentContext(), SetCurrentContext(). + - 2016/05/02 (1.49) - renamed SetNextTreeNodeOpened() to SetNextTreeNodeOpen(), no redirection. + - 2016/05/01 (1.49) - obsoleted old signature of CollapsingHeader(const char* label, const char* str_id = NULL, bool display_frame = true, bool default_open = false) as extra parameters were badly designed and rarely used. You can replace the "default_open = true" flag in new API with CollapsingHeader(label, ImGuiTreeNodeFlags_DefaultOpen). + - 2016/04/26 (1.49) - changed ImDrawList::PushClipRect(ImVec4 rect) to ImDrawList::PushClipRect(Imvec2 min,ImVec2 max,bool intersect_with_current_clip_rect=false). Note that higher-level ImGui::PushClipRect() is preferable because it will clip at logic/widget level, whereas ImDrawList::PushClipRect() only affect your renderer. + - 2016/04/03 (1.48) - removed style.WindowFillAlphaDefault setting which was redundant. Bake default BG alpha inside style.Colors[ImGuiCol_WindowBg] and all other Bg color values. (ref GitHub issue #337). + - 2016/04/03 (1.48) - renamed ImGuiCol_TooltipBg to ImGuiCol_PopupBg, used by popups/menus and tooltips. popups/menus were previously using ImGuiCol_WindowBg. (ref github issue #337) + - 2016/03/21 (1.48) - renamed GetWindowFont() to GetFont(), GetWindowFontSize() to GetFontSize(). Kept inline redirection function (will obsolete). + - 2016/03/02 (1.48) - InputText() completion/history/always callbacks: if you modify the text buffer manually (without using DeleteChars()/InsertChars() helper) you need to maintain the BufTextLen field. added an assert. + - 2016/01/23 (1.48) - fixed not honoring exact width passed to PushItemWidth(), previously it would add extra FramePadding.x*2 over that width. if you had manual pixel-perfect alignment in place it might affect you. + - 2015/12/27 (1.48) - fixed ImDrawList::AddRect() which used to render a rectangle 1 px too large on each axis. + - 2015/12/04 (1.47) - renamed Color() helpers to ValueColor() - dangerously named, rarely used and probably to be made obsolete. + - 2015/08/29 (1.45) - with the addition of horizontal scrollbar we made various fixes to inconsistencies with dealing with cursor position. + GetCursorPos()/SetCursorPos() functions now include the scrolled amount. It shouldn't affect the majority of users, but take note that SetCursorPosX(100.0f) puts you at +100 from the starting x position which may include scrolling, not at +100 from the window left side. + GetContentRegionMax()/GetWindowContentRegionMin()/GetWindowContentRegionMax() functions allow include the scrolled amount. Typically those were used in cases where no scrolling would happen so it may not be a problem, but watch out! + - 2015/08/29 (1.45) - renamed style.ScrollbarWidth to style.ScrollbarSize + - 2015/08/05 (1.44) - split imgui.cpp into extra files: imgui_demo.cpp imgui_draw.cpp imgui_internal.h that you need to add to your project. + - 2015/07/18 (1.44) - fixed angles in ImDrawList::PathArcTo(), PathArcToFast() (introduced in 1.43) being off by an extra PI for no justifiable reason + - 2015/07/14 (1.43) - add new ImFontAtlas::AddFont() API. For the old AddFont***, moved the 'font_no' parameter of ImFontAtlas::AddFont** functions to the ImFontConfig structure. + you need to render your textured triangles with bilinear filtering to benefit from sub-pixel positioning of text. + - 2015/07/08 (1.43) - switched rendering data to use indexed rendering. this is saving a fair amount of CPU/GPU and enables us to get anti-aliasing for a marginal cost. + this necessary change will break your rendering function! the fix should be very easy. sorry for that :( + - if you are using a vanilla copy of one of the imgui_impl_XXX.cpp provided in the example, you just need to update your copy and you can ignore the rest. + - the signature of the io.RenderDrawListsFn handler has changed! + old: ImGui_XXXX_RenderDrawLists(ImDrawList** const cmd_lists, int cmd_lists_count) + new: ImGui_XXXX_RenderDrawLists(ImDrawData* draw_data). + parameters: 'cmd_lists' becomes 'draw_data->CmdLists', 'cmd_lists_count' becomes 'draw_data->CmdListsCount' + ImDrawList: 'commands' becomes 'CmdBuffer', 'vtx_buffer' becomes 'VtxBuffer', 'IdxBuffer' is new. + ImDrawCmd: 'vtx_count' becomes 'ElemCount', 'clip_rect' becomes 'ClipRect', 'user_callback' becomes 'UserCallback', 'texture_id' becomes 'TextureId'. + - each ImDrawList now contains both a vertex buffer and an index buffer. For each command, render ElemCount/3 triangles using indices from the index buffer. + - if you REALLY cannot render indexed primitives, you can call the draw_data->DeIndexAllBuffers() method to de-index the buffers. This is slow and a waste of CPU/GPU. Prefer using indexed rendering! + - refer to code in the examples/ folder or ask on the GitHub if you are unsure of how to upgrade. please upgrade! + - 2015/07/10 (1.43) - changed SameLine() parameters from int to float. + - 2015/07/02 (1.42) - renamed SetScrollPosHere() to SetScrollFromCursorPos(). Kept inline redirection function (will obsolete). + - 2015/07/02 (1.42) - renamed GetScrollPosY() to GetScrollY(). Necessary to reduce confusion along with other scrolling functions, because positions (e.g. cursor position) are not equivalent to scrolling amount. + - 2015/06/14 (1.41) - changed ImageButton() default bg_col parameter from (0,0,0,1) (black) to (0,0,0,0) (transparent) - makes a difference when texture have transparence + - 2015/06/14 (1.41) - changed Selectable() API from (label, selected, size) to (label, selected, flags, size). Size override should have been rarely used. Sorry! + - 2015/05/31 (1.40) - renamed GetWindowCollapsed() to IsWindowCollapsed() for consistency. Kept inline redirection function (will obsolete). + - 2015/05/31 (1.40) - renamed IsRectClipped() to IsRectVisible() for consistency. Note that return value is opposite! Kept inline redirection function (will obsolete). + - 2015/05/27 (1.40) - removed the third 'repeat_if_held' parameter from Button() - sorry! it was rarely used and inconsistent. Use PushButtonRepeat(true) / PopButtonRepeat() to enable repeat on desired buttons. + - 2015/05/11 (1.40) - changed BeginPopup() API, takes a string identifier instead of a bool. ImGui needs to manage the open/closed state of popups. Call OpenPopup() to actually set the "open" state of a popup. BeginPopup() returns true if the popup is opened. + - 2015/05/03 (1.40) - removed style.AutoFitPadding, using style.WindowPadding makes more sense (the default values were already the same). + - 2015/04/13 (1.38) - renamed IsClipped() to IsRectClipped(). Kept inline redirection function until 1.50. + - 2015/04/09 (1.38) - renamed ImDrawList::AddArc() to ImDrawList::AddArcFast() for compatibility with future API + - 2015/04/03 (1.38) - removed ImGuiCol_CheckHovered, ImGuiCol_CheckActive, replaced with the more general ImGuiCol_FrameBgHovered, ImGuiCol_FrameBgActive. + - 2014/04/03 (1.38) - removed support for passing -FLT_MAX..+FLT_MAX as the range for a SliderFloat(). Use DragFloat() or Inputfloat() instead. + - 2015/03/17 (1.36) - renamed GetItemBoxMin()/GetItemBoxMax()/IsMouseHoveringBox() to GetItemRectMin()/GetItemRectMax()/IsMouseHoveringRect(). Kept inline redirection function until 1.50. + - 2015/03/15 (1.36) - renamed style.TreeNodeSpacing to style.IndentSpacing, ImGuiStyleVar_TreeNodeSpacing to ImGuiStyleVar_IndentSpacing + - 2015/03/13 (1.36) - renamed GetWindowIsFocused() to IsWindowFocused(). Kept inline redirection function until 1.50. + - 2015/03/08 (1.35) - renamed style.ScrollBarWidth to style.ScrollbarWidth (casing) + - 2015/02/27 (1.34) - renamed OpenNextNode(bool) to SetNextTreeNodeOpened(bool, ImGuiSetCond). Kept inline redirection function until 1.50. + - 2015/02/27 (1.34) - renamed ImGuiSetCondition_*** to ImGuiSetCond_***, and _FirstUseThisSession becomes _Once. + - 2015/02/11 (1.32) - changed text input callback ImGuiTextEditCallback return type from void-->int. reserved for future use, return 0 for now. + - 2015/02/10 (1.32) - renamed GetItemWidth() to CalcItemWidth() to clarify its evolving behavior + - 2015/02/08 (1.31) - renamed GetTextLineSpacing() to GetTextLineHeightWithSpacing() + - 2015/02/01 (1.31) - removed IO.MemReallocFn (unused) + - 2015/01/19 (1.30) - renamed ImGuiStorage::GetIntPtr()/GetFloatPtr() to GetIntRef()/GetIntRef() because Ptr was conflicting with actual pointer storage functions. + - 2015/01/11 (1.30) - big font/image API change! now loads TTF file. allow for multiple fonts. no need for a PNG loader. + - 2015/01/11 (1.30) - removed GetDefaultFontData(). uses io.Fonts->GetTextureData*() API to retrieve uncompressed pixels. + - old: const void* png_data; unsigned int png_size; ImGui::GetDefaultFontData(NULL, NULL, &png_data, &png_size); [..Upload texture to GPU..]; + - new: unsigned char* pixels; int width, height; io.Fonts->GetTexDataAsRGBA32(&pixels, &width, &height); [..Upload texture to GPU..]; io.Fonts->SetTexID(YourTexIdentifier); + you now have more flexibility to load multiple TTF fonts and manage the texture buffer for internal needs. It is now recommended that you sample the font texture with bilinear interpolation. + - 2015/01/11 (1.30) - added texture identifier in ImDrawCmd passed to your render function (we can now render images). make sure to call io.Fonts->SetTexID() + - 2015/01/11 (1.30) - removed IO.PixelCenterOffset (unnecessary, can be handled in user projection matrix) + - 2015/01/11 (1.30) - removed ImGui::IsItemFocused() in favor of ImGui::IsItemActive() which handles all widgets + - 2014/12/10 (1.18) - removed SetNewWindowDefaultPos() in favor of new generic API SetNextWindowPos(pos, ImGuiSetCondition_FirstUseEver) + - 2014/11/28 (1.17) - moved IO.Font*** options to inside the IO.Font-> structure (FontYOffset, FontTexUvForWhite, FontBaseScale, FontFallbackGlyph) + - 2014/11/26 (1.17) - reworked syntax of IMGUI_ONCE_UPON_A_FRAME helper macro to increase compiler compatibility + - 2014/11/07 (1.15) - renamed IsHovered() to IsItemHovered() + - 2014/10/02 (1.14) - renamed IMGUI_INCLUDE_IMGUI_USER_CPP to IMGUI_INCLUDE_IMGUI_USER_INL and imgui_user.cpp to imgui_user.inl (more IDE friendly) + - 2014/09/25 (1.13) - removed 'text_end' parameter from IO.SetClipboardTextFn (the string is now always zero-terminated for simplicity) + - 2014/09/24 (1.12) - renamed SetFontScale() to SetWindowFontScale() + - 2014/09/24 (1.12) - moved IM_MALLOC/IM_REALLOC/IM_FREE preprocessor defines to IO.MemAllocFn/IO.MemReallocFn/IO.MemFreeFn + - 2014/08/30 (1.09) - removed IO.FontHeight (now computed automatically) + - 2014/08/30 (1.09) - moved IMGUI_FONT_TEX_UV_FOR_WHITE preprocessor define to IO.FontTexUvForWhite + - 2014/08/28 (1.09) - changed the behavior of IO.PixelCenterOffset following various rendering fixes + + + FREQUENTLY ASKED QUESTIONS (FAQ) + ================================ + + Read all answers online: + https://www.dearimgui.com/faq or https://github.com/ocornut/imgui/blob/master/docs/FAQ.md (same url) + Read all answers locally (with a text editor or ideally a Markdown viewer): + docs/FAQ.md + Some answers are copied down here to facilitate searching in code. + + Q&A: Basics + =========== + + Q: Where is the documentation? + A: This library is poorly documented at the moment and expects the user to be acquainted with C/C++. + - Run the examples/ applications and explore them. + - Read Getting Started (https://github.com/ocornut/imgui/wiki/Getting-Started) guide. + - See demo code in imgui_demo.cpp and particularly the ImGui::ShowDemoWindow() function. + - The demo covers most features of Dear ImGui, so you can read the code and see its output. + - See documentation and comments at the top of imgui.cpp + effectively imgui.h. + - 20+ standalone example applications using e.g. OpenGL/DirectX are provided in the + examples/ folder to explain how to integrate Dear ImGui with your own engine/application. + - The Wiki (https://github.com/ocornut/imgui/wiki) has many resources and links. + - The Glossary (https://github.com/ocornut/imgui/wiki/Glossary) page also may be useful. + - Your programming IDE is your friend, find the type or function declaration to find comments + associated with it. + + Q: What is this library called? + Q: What is the difference between Dear ImGui and traditional UI toolkits? + Q: Which version should I get? + >> This library is called "Dear ImGui", please don't call it "ImGui" :) + >> See https://www.dearimgui.com/faq for details. + + Q&A: Integration + ================ + + Q: How to get started? + A: Read https://github.com/ocornut/imgui/wiki/Getting-Started.

For our other sources files we use them, and they are provided +// by imgui.h using the IMGUI_DEFINE_MATH_OPERATORS define. For your own sources file they are optional +// and require you either enable those, either provide your own via IM_VEC2_CLASS_EXTRA in imconfig.h. +// Because we can't assume anything about your support of maths operators, we cannot use them in imgui_demo.cpp. + +// Navigating this file: +// - In Visual Studio: Ctrl+Comma ("Edit.GoToAll") can follow symbols inside comments, whereas Ctrl+F12 ("Edit.GoToImplementation") cannot. +// - In Visual Studio w/ Visual Assist installed: Alt+G ("VAssistX.GoToImplementation") can also follow symbols inside comments. +// - In VS Code, CLion, etc.: Ctrl+Click can follow symbols inside comments. +// - You can search/grep for all sections listed in the index to find the section. + +/* + +Index of this file: + +// [SECTION] Forward Declarations +// [SECTION] Helpers +// [SECTION] Demo Window / ShowDemoWindow() +// [SECTION] DemoWindowMenuBar() +// [SECTION] Helpers: ExampleTreeNode, ExampleMemberInfo (for use by Property Editor & Multi-Select demos) +// [SECTION] DemoWindowWidgetsBasic() +// [SECTION] DemoWindowWidgetsBullets() +// [SECTION] DemoWindowWidgetsCollapsingHeaders() +// [SECTION] DemoWindowWidgetsComboBoxes() +// [SECTION] DemoWindowWidgetsColorAndPickers() +// [SECTION] DemoWindowWidgetsDataTypes() +// [SECTION] DemoWindowWidgetsDisableBlocks() +// [SECTION] DemoWindowWidgetsDragAndDrop() +// [SECTION] DemoWindowWidgetsDragsAndSliders() +// [SECTION] DemoWindowWidgetsFonts() +// [SECTION] DemoWindowWidgetsImages() +// [SECTION] DemoWindowWidgetsListBoxes() +// [SECTION] DemoWindowWidgetsMultiComponents() +// [SECTION] DemoWindowWidgetsPlotting() +// [SECTION] DemoWindowWidgetsProgressBars() +// [SECTION] DemoWindowWidgetsQueryingStatuses() +// [SECTION] DemoWindowWidgetsSelectables() +// [SECTION] DemoWindowWidgetsSelectionAndMultiSelect() +// [SECTION] DemoWindowWidgetsTabs() +// [SECTION] DemoWindowWidgetsText() +// [SECTION] DemoWindowWidgetsTextFilter() +// [SECTION] DemoWindowWidgetsTextInput() +// [SECTION] DemoWindowWidgetsTooltips() +// [SECTION] DemoWindowWidgetsTreeNodes() +// [SECTION] DemoWindowWidgetsVerticalSliders() +// [SECTION] DemoWindowWidgets() +// [SECTION] DemoWindowLayout() +// [SECTION] DemoWindowPopups() +// [SECTION] DemoWindowTables() +// [SECTION] DemoWindowInputs() +// [SECTION] About Window / ShowAboutWindow() +// [SECTION] Style Editor / ShowStyleEditor() +// [SECTION] User Guide / ShowUserGuide() +// [SECTION] Example App: Main Menu Bar / ShowExampleAppMainMenuBar() +// [SECTION] Example App: Debug Console / ShowExampleAppConsole() +// [SECTION] Example App: Debug Log / ShowExampleAppLog() +// [SECTION] Example App: Simple Layout / ShowExampleAppLayout() +// [SECTION] Example App: Property Editor / ShowExampleAppPropertyEditor() +// [SECTION] Example App: Long Text / ShowExampleAppLongText() +// [SECTION] Example App: Auto Resize / ShowExampleAppAutoResize() +// [SECTION] Example App: Constrained Resize / ShowExampleAppConstrainedResize() +// [SECTION] Example App: Simple overlay / ShowExampleAppSimpleOverlay() +// [SECTION] Example App: Fullscreen window / ShowExampleAppFullscreen() +// [SECTION] Example App: Manipulating window titles / ShowExampleAppWindowTitles() +// [SECTION] Example App: Custom Rendering using ImDrawList API / ShowExampleAppCustomRendering() +// [SECTION] Example App: Docking, DockSpace / ShowExampleAppDockSpace() +// [SECTION] Example App: Documents Handling / ShowExampleAppDocuments() +// [SECTION] Example App: Assets Browser / ShowExampleAppAssetsBrowser() + +*/ + +#if defined(_MSC_VER) && !defined(_CRT_SECURE_NO_WARNINGS) +#define _CRT_SECURE_NO_WARNINGS +#endif + +#include "imgui.h" +#ifndef IMGUI_DISABLE + +// System includes +#include // toupper +#include // INT_MIN, INT_MAX +#include // sqrtf, powf, cosf, sinf, floorf, ceilf +#include // vsnprintf, sscanf, printf +#include // NULL, malloc, free, atoi +#include // intptr_t +#if !defined(_MSC_VER) || _MSC_VER >= 1800 +#include // PRId64/PRIu64, not avail in some MinGW headers. +#endif +#ifdef __EMSCRIPTEN__ +#include // __EMSCRIPTEN_major__ etc. +#endif + +// Visual Studio warnings +#ifdef _MSC_VER +#pragma warning (disable: 4127) // condition expression is constant +#pragma warning (disable: 4996) // 'This function or variable may be unsafe': strcpy, strdup, sprintf, vsnprintf, sscanf, fopen +#pragma warning (disable: 26451) // [Static Analyzer] Arithmetic overflow : Using operator 'xxx' on a 4 byte value and then casting the result to an 8 byte value.

You will then +// need to provide your own APIs in the same file which will access the +// static functions. +// +// The basic concept is that you provide a "string" object which +// behaves like an array of characters. stb_textedit uses indices to +// refer to positions in the string, implicitly representing positions +// in the displayed textedit.

STB_TEXTEDIT_KEYTYPE defaults to int, but you can #define it to +// anything other type you want before including. +// if the STB_TEXTEDIT_KEYTOTEXT function is defined, selected keys are +// transformed into text and stb_textedit_text() is automatically called. +// +// text: (added 2025) +// call this to directly send text input the textfield, which is required +// for UTF-8 support, because stb_textedit_key() + STB_TEXTEDIT_KEYTOTEXT() +// cannot infer text length. +// +// +// When rendering, you can read the cursor position and selection state from +// the STB_TexteditState. +// +// +// Notes: +// +// This is designed to be usable in IMGUI, so it allows for the possibility of +// running in an IMGUI that has NOT cached the multi-line layout. For this +// reason, it provides an interface that is compatible with computing the +// layout incrementally--we try to make sure we make as few passes through +// as possible. (For example, to locate the mouse pointer in the text, we +// could define functions that return the X and Y positions of characters +// and binary search Y and then X, but if we're doing dynamic layout this +// will run the layout algorithm many times, so instead we manually search +// forward in one pass. Similar logic applies to e.g. up-arrow and +// down-arrow movement.) +// +// If it's run in a widget that *has* cached the layout, then this is less +// efficient, but it's not horrible on modern computers. But you wouldn't +// want to edit million-line files with it. + + +//////////////////////////////////////////////////////////////////////////// +//////////////////////////////////////////////////////////////////////////// +//// +//// Header-file mode +//// +//// + +#ifndef INCLUDE_IMSTB_TEXTEDIT_H +#define INCLUDE_IMSTB_TEXTEDIT_H + +//////////////////////////////////////////////////////////////////////// +// +// STB_TexteditState +// +// Definition of STB_TexteditState which you should store +// per-textfield;

This section +// includes documentation for each API function. +// +// Some important concepts to understand to use this library: +// +// Codepoint +// Characters are defined by unicode codepoints, e.g. 65 is +// uppercase A, 231 is lowercase c with a cedilla, 0x7e30 is +// the hiragana for "ma". +// +// Glyph +// A visual character shape (every codepoint is rendered as +// some glyph) +// +// Glyph index +// A font-specific integer ID representing a glyph +// +// Baseline +// Glyph shapes are defined relative to a baseline, which is the +// bottom of uppercase characters. Characters extend both above +// and below the baseline. +// +// Current Point +// As you draw text to the screen, you keep track of a "current point" +// which is the origin of each character. The current point's vertical +// position is the baseline. Even "baked fonts" use this model. +// +// Vertical Font Metrics +// The vertical qualities of the font, used to vertically position +// and space the characters. See docs for stbtt_GetFontVMetrics. +// +// Font Size in Pixels or Points +// The preferred interface for specifying font sizes in stb_truetype +// is to specify how tall the font's vertical extent should be in pixels. +// If that sounds good enough, skip the next paragraph. +// +// Most font APIs instead use "points", which are a common typographic +// measurement for describing font size, defined as 72 points per inch. +// stb_truetype provides a point API for compatibility. However, true +// "per inch" conventions don't make much sense on computer displays +// since different monitors have different number of pixels per +// inch. For example, Windows traditionally uses a convention that +// there are 96 pixels per inch, thus making 'inch' measurements have +// nothing to do with inches, and thus effectively defining a point to +// be 1.333 pixels. Additionally, the TrueType font data provides +// an explicit scale factor to scale a given font's glyphs to points, +// but the author has observed that this scale factor is often wrong +// for non-commercial fonts, thus making fonts scaled in points +// according to the TrueType spec incoherently sized in practice. +// +// DETAILED USAGE: +// +// Scale: +// Select how high you want the font to be, in points or pixels. +// Call ScaleForPixelHeight or ScaleForMappingEmToPixels to compute +// a scale factor SF that will be used by all other functions. +// +// Baseline: +// You need to select a y-coordinate that is the baseline of where +// your text will appear. Call GetFontBoundingBox to get the baseline-relative +// bounding box for all characters. SF*-y0 will be the distance in pixels +// that the worst-case character could extend above the baseline, so if +// you want the top edge of characters to appear at the top of the +// screen where y=0, then you would set the baseline to SF*-y0. +// +// Current point: +// Set the current point where the first character will appear. The +// first character could extend left of the current point; this is font +// dependent. You can either choose a current point that is the leftmost +// point and hope, or add some padding, or check the bounding box or +// left-side-bearing of the first character to be displayed and set +// the current point based on that. +// +// Displaying a character: +// Compute the bounding box of the character. It will contain signed values +// relative to .

For example, to disable the archive related functions just define + MINIZ_NO_ARCHIVE_APIS, or to get rid of all stdio usage define MINIZ_NO_STDIO (see the list below for more macros). + + * Low-level Deflate/Inflate implementation notes: + + Compression: Use the "tdefl" API's. The compressor supports raw, static, and dynamic blocks, lazy or + greedy parsing, match length filtering, RLE-only, and Huffman-only streams. It performs and compresses + approximately as well as zlib. + + Decompression: Use the "tinfl" API's. The entire decompressor is implemented as a single function + coroutine: see tinfl_decompress(). It supports decompression into a 32KB (or larger power of 2) wrapping buffer, or into a memory + block large enough to hold the entire file. + + The low-level tdefl/tinfl API's do not make any use of dynamic memory allocation. + + * zlib-style API notes: + + miniz.c implements a fairly large subset of zlib.

No support for gzip headers or zlib static dictionaries. + I've tried to closely emulate zlib's various flavors of stream flushing and return status codes, but + there are no guarantees that miniz.c pulls this off perfectly. + + * PNG writing: See the tdefl_write_image_to_png_file_in_memory() function, originally written by + Alex Evans. Supports 1-4 bytes/pixel images. + + * ZIP archive API notes: + + The ZIP archive API's where designed with simplicity and efficiency in mind, with just enough abstraction to + get the job done with minimal fuss. There are simple API's to retrieve file information, read files from + existing archives, create new archives, append new files to existing archives, or clone archive data from + one archive to another. It supports archives located in memory or the heap, on disk (using stdio.h), + or you can specify custom file read/write callbacks. + + - Archive reading: Just call this function to read a single file from a disk archive: + + void *mz_zip_extract_archive_file_to_heap(const char *pZip_filename, const char *pArchive_name, + size_t *pSize, mz_uint zip_flags); + + For more complex cases, use the "mz_zip_reader" functions. Upon opening an archive, the entire central + directory is located and read as-is into memory, and subsequent file access only occurs when reading individual files. + + - Archives file scanning: The simple way is to use this function to scan a loaded archive for a specific file: + + int mz_zip_reader_locate_file(mz_zip_archive *pZip, const char *pName, const char *pComment, mz_uint flags); + + The locate operation can optionally check file comments too, which (as one example) can be used to identify + multiple versions of the same file in an archive. This function uses a simple linear search through the central + directory, so it's not very fast. + + Alternately, you can iterate through all the files in an archive (using mz_zip_reader_get_num_files()) and + retrieve detailed info on each file by calling mz_zip_reader_file_stat(). + + - Archive creation: Use the "mz_zip_writer" functions. The ZIP writer immediately writes compressed file data + to disk and builds an exact image of the central directory in memory. The central directory image is written + all at once at the end of the archive file when the archive is finalized. + + The archive writer can optionally align each file's local header and file data to any power of 2 alignment, + which can be useful when the archive will be read from optical media. Also, the writer supports placing + arbitrary data blobs at the very beginning of ZIP archives. Archives written using either feature are still + readable by any ZIP tool. + + - Archive appending: The simple way to add a single file to an archive is to call this function: + + mz_bool mz_zip_add_mem_to_archive_file_in_place(const char *pZip_filename, const char *pArchive_name, + const void *pBuf, size_t buf_size, const void *pComment, mz_uint16 comment_size, mz_uint level_and_flags); + + The archive will be created if it doesn't already exist, otherwise it'll be appended to. + Note the appending is done in-place and is not an atomic operation, so if something goes wrong + during the operation it's possible the archive could be left without a central directory (although the local + file headers and file data will be fine, so the archive will be recoverable). + + For more complex archive modification scenarios: + 1. The safest way is to use a mz_zip_reader to read the existing archive, cloning only those bits you want to + preserve into a new archive using using the mz_zip_writer_add_from_zip_reader() function (which compiles the + compressed file data as-is). When you're done, delete the old archive and rename the newly written archive, and + you're done. This is safe but requires a bunch of temporary disk space or heap memory. + + 2. Or, you can convert an mz_zip_reader in-place to an mz_zip_writer using mz_zip_writer_init_from_reader(), + append new files as needed, then finalize the archive which will write an updated central directory to the + original archive. (This is basically what mz_zip_add_mem_to_archive_file_in_place() does.) There's a + possibility that the archive's central directory could be lost with this method if anything goes wrong, though. + + - ZIP archive support limitations: + No spanning support. Extraction functions can only handle unencrypted, stored or deflated files. + Requires streams capable of seeking. + + * This is a header file library, like stb_image.c. To get only a header file, either cut and paste the + below header, or create miniz.h, #define MINIZ_HEADER_FILE_ONLY, and then include miniz.c from it. + + * Important: For best perf. be sure to customize the below macros for your target platform: + #define MINIZ_USE_UNALIGNED_LOADS_AND_STORES 1 + #define MINIZ_LITTLE_ENDIAN 1 + #define MINIZ_HAS_64BIT_REGISTERS 1 + + * On platforms using

This is now part of the API and thus +// hard to change without causing breakage. As a result, the various image +// loaders all have certain limits on image size; these differ somewhat +// by format but generally boil down to either just under 2GB or just under +// 1GB. When the decoded image would be larger than this, stb_image decoding +// will fail. +// +// Additionally, stb_image will reject image files that have any of their +// dimensions set to a larger value than the configurable STBI_MAX_DIMENSIONS, +// which defaults to 2**24 = 16777216 pixels. Due to the above memory limit, +// the only way to have an image with such dimensions load correctly +// is for it to have a rather extreme aspect ratio. Either way, the +// assumption here is that such larger images are likely to be malformed +// or malicious. If you do need to load an image with individual dimensions +// larger than that, and it still fits in the overall size limit, you can +// #define STBI_MAX_DIMENSIONS on your own to be something larger. +// +// =========================================================================== +// +// UNICODE: +// +// If compiling for Windows and you wish to use Unicode filenames, compile +// with +// #define STBI_WINDOWS_UTF8 +// and pass utf8-encoded filenames.

Nevertheless, it's important +// to keep in mind that from the standpoint of you, a client of this library, +// all you care about is #1 and #3, and stb libraries DO NOT emphasize #3 above all. +// +// Some secondary priorities arise directly from the first two, some of which +// provide more explicit reasons why performance can't be emphasized. +// +// - Portable ("ease of use") +// - Small source code footprint ("easy to maintain") +// - No dependencies ("ease of use") +// +// =========================================================================== +// +// I/O callbacks +// +// I/O callbacks allow you to read from arbitrary sources, like packaged +// files or some other source. Data read from callbacks are processed +// through a small internal buffer (currently 128 bytes) to try to reduce +// overhead. +// +// The three functions you must define are "read" (reads some bytes of data), +// "skip" (skips some bytes of data), "eof" (reports if the stream is at the end). +// +// =========================================================================== +// +// SIMD support +// +// The JPEG decoder will try to automatically use SIMD kernels on x86 when +// supported by the compiler. For ARM Neon support, you must explicitly +// request it. +// +// (The old do-it-yourself SIMD API is no longer supported in the current +// code.) +// +// On x86, SSE2 will automatically be used when available based on a run-time +// test; if not, the generic C versions are used as a fall-back. On ARM targets, +// the typical path is to have separate builds for NEON and non-NEON devices +// (at least this is true for iOS and Android). Therefore, the NEON support is +// toggled by a build flag: define STBI_NEON to get NEON loops. +// +// If for some reason you do not want to use any of SIMD code, or if +// you have issues compiling it, you can disable it entirely by +// defining STBI_NO_SIMD. +// +// =========================================================================== +// +// HDR image support (disable by defining STBI_NO_HDR) +// +// stb_image supports loading HDR images in general, and currently the Radiance +// .HDR file format specifically. You can still load any file through the existing +// interface; if you attempt to load an HDR file, it will be automatically remapped +// to LDR, assuming gamma 2.2 and an arbitrary scale factor defaulting to 1; +// both of these constants can be reconfigured through this interface: +// +// stbi_hdr_to_ldr_gamma(2.2f); +// stbi_hdr_to_ldr_scale(1.0f); +// +// (note, do not use _inverse_ constants; stbi_image will invert them +// appropriately). +// +// Additionally, there is a new, parallel interface for loading files as +// (linear) floats to preserve the full dynamic range: +// +// float *data = stbi_loadf(filename, &x, &y, &n, 0); +// +// If you load LDR images through this interface, those images will +// be promoted to floating point values, run through the inverse of +// constants corresponding to the above: +// +// stbi_ldr_to_hdr_scale(1.0f); +// stbi_ldr_to_hdr_gamma(2.2f); +// +// Finally, given a filename (or an open file or memory block--see header +// file for details) containing image data, you can query for the "most +// appropriate" interface to use (that is, whether the image is HDR or +// not), using: +// +// stbi_is_hdr(char *filename); +// +// =========================================================================== +// +// iPhone PNG support: +// +// We optionally support converting iPhone-formatted PNGs (which store +// premultiplied BGRA) back to RGB, even though they're internally encoded +// differently. To enable this conversion, call +// stbi_convert_iphone_png_to_rgb(1). +// +// Call stbi_set_unpremultiply_on_load(1) as well to force a divide per +// pixel to remove any premultiplied alpha *only* if the image file explicitly +// says there's premultiplied data (currently only happens in iPhone images, +// and only if iPhone convert-to-rgb processing is on). +// +// =========================================================================== +// +// ADDITIONAL CONFIGURATION +// +// - You can suppress implementation of any of the decoders to reduce +// your code footprint by #defining one or more of the following +// symbols before creating the implementation. +// +// STBI_NO_JPEG +// STBI_NO_PNG +// STBI_NO_BMP +// STBI_NO_PSD +// STBI_NO_TGA +// STBI_NO_GIF +// STBI_NO_HDR +// STBI_NO_PIC +// STBI_NO_PNM (.ppm and .pgm) +// +// - You can request *only* certain decoders and suppress all other ones +// (this will be more forward-compatible, as addition of new decoders +// doesn't require you to disable them explicitly): +// +// STBI_ONLY_JPEG +// STBI_ONLY_PNG +// STBI_ONLY_BMP +// STBI_ONLY_PSD +// STBI_ONLY_TGA +// STBI_ONLY_GIF +// STBI_ONLY_HDR +// STBI_ONLY_PIC +// STBI_ONLY_PNM (.ppm and .pgm) +// +// - If you use STBI_NO_PNG (or _ONLY_ without PNG), and you still +// want the zlib decoder to be available, #define STBI_SUPPORT_ZLIB +// +// - If you define STBI_MAX_DIMENSIONS, stb_image will reject images greater +// than that size (in either width or height) without further processing. +// This is to let programs in the wild set an upper bound to prevent +// denial-of-service attacks on untrusted data, as one could generate a +// valid image of gigantic dimensions and force stb_image to allocate a +// huge block of memory and spend disproportionate time decoding it.
