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.

If you like to contribute, report bugs, see [how to contribute document](CONTRIBUTING.md)

Downloads/etc...

Please visit our homepage for more details.

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.
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
- NOTE libimagequant is dual-licensed: GPLv3 and commercial license

Platforms supported

CI means whether we have an automatic CI for this platform. If someone has CI for these platforms or any other platforms not listed here and would like to add them to our automatic CI, please get in touch with us, it will much appreciated!

Platform	Support	CI
Linux x64	✓	✓
Linux x86	✓	✓
Linux ARM64	✓	✓
Windows x86	✓	✓
Windows x64	✓	✓
Windows arm64	✓	x
MacOS x64	✓	✓
MacOS M1	✓	x
S390	✓	x

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
