# Libraries These libraries can extend the core SDL functionality. Please note that several of these have names that start with "SDL_", but none of them are part of the core SDL library. They are _separate_ and _optional_ extras! ## Dear ImGUI: Dear ImGui is a bloat-free graphical user interface library for C++. It outputs optimized vertex buffers that you can render anytime in your 3D-pipeline-enabled application. It is fast, portable, renderer agnostic, and self-contained (no external dependencies). - [Dear ImGui website](https://github.com/ocornut/imgui) ## RmlUI: RmlUi is the C++ user interface package based on the HTML and CSS standards, designed as a complete solution for any project's interface needs. It is a fork of the libRocket project, introducing new features, bug fixes, and performance improvements. - [RmlUI website](https://github.com/mikke89/RmlUi) - [Example source code](https://github.com/mikke89/RmlUi/tree/master/Backends) ## SDL_gfx Provides the basic drawing functions such as lines, circles or polygons. - [Git Repository](https://github.com/sabdul-khabir/SDL3_gfx) ## SDL_image Loads images as SDL surfaces and textures, and supports the following formats: BMP, GIF, JPEG, LBM, PCX, PNG, PNM, QOI, SVG, TGA, TIFF, WEBP, XCF, XPM, XV (and more!) - [Latest Release](https://github.com/libsdl-org/SDL_image/releases/latest) - [Git Repository](https://github.com/libsdl-org/SDL_image) - [Wiki](https://wiki.libsdl.org/SDL3_image) ## SDL_mixer SDL_mixer is a sample multi-channel audio mixer library. It supports any number of simultaneously playing channels of 16 bit stereo audio, plus a single channel of music, mixed by the popular FLAC, MikMod MOD, Timidity MIDI, Ogg Vorbis, and SMPEG MP3 libraries. SDL_mixer works with SDL3 but we intend to update the API significantly for a 3.0 release. - [Git Repository](https://github.com/libsdl-org/SDL_mixer) - [Wiki](https://wiki.libsdl.org/SDL3_mixer) ## SDL_ttf A library which allows you to use TrueType fonts in your SDL applications. It comes with an example program "showfont" which displays an example string for a given TrueType font file. SDL_ttf works with SDL3 and has a 3.0 [preview release](https://github.com/libsdl-org/SDL_ttf/releases/tag/preview-3.1.0) available. - [Git Repository](https://github.com/libsdl-org/SDL_ttf) - [Wiki](https://wiki.libsdl.org/SDL3_ttf) ## SDL_net A small cross-platform networking library. SDL_net works with SDL3 and we have some more polish work to do for a 3.0 release. - [Git Repository](https://github.com/libsdl-org/SDL_net) - [Wiki](https://wiki.libsdl.org/SDL3_net) ## SDL_shadercross A library for translating shaders to different formats. Intended for use with the [GPU API](https://wiki.libsdl.org/SDL3/CategoryGPU). - [Git Repository](https://github.com/libsdl-org/SDL_shadercross)
