GD Graphics (Draw) Library
GD is an open source code library for the dynamic creation of images by programmers.
GD is written in C, and "wrappers" are available for Perl, PHP and other languages. GD can read and write many different image formats. GD is commonly used to generate charts, graphics, thumbnails, and most anything else, on the fly.
The most common applications of GD involve website development, although it can be used with any standalone application!
The library was originally developed by Thomas Boutell and is now maintained by many contributors (see the [CONTRIBUTORS](CONTRIBUTORS) file) under the umbrella of PHP.net.

Supported Image Formats
GD has support for:
- WebP via libwebp
- JPEG via IJG/libjpeg or libjpeg-turbo
- Does not include JPEG 2000
- PNG via libpng
- AVIF via libavif
- This includes AVIF read support if your system's
libheif
has AV1 decoding.
- This includes AVIF read support if your system's
- HEIF via libheif
- TIFF via libtiff
- BMP (builtin)
- GIF (builtin)
- TGA (builtin)
- WBMP (builtin)
- XPM via libXpm
Besides that, GD depends on some external libraries, which are all optional and disabled by default:
- FreeType for rendering fonts
- Fontconfig for configuring and customizing font access
- libraqm for complex text layout
- libimagequant for conversion of RGBA images to 8-bit indexed-color images

It is also known to work on almost all variations of *BSD, Solaris, etc. We don't have CI nor environment to test them. However many progamming languages binding do test libgd on these platforms.
Compilers
It should compile with all C99 and C++ compliant compilers, either using CMake or the configure script.
We do have CI using:
- GCC
- CLang
- Visual Studio
- Xcode
- MingW
