# 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).

## 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.

## 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.

## 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.

## 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.
