1 GD is an open source code library for the dynamic creation of images
2 by programmers.
3 GD is written in C, and "wrappers" are available for Perl, PHP, ruby
4 and many other bindings.
6 GD has builtin support for:
8 * BMP (builtin)
9 * GIF with animation support (builtin)
10 * TGA (builtin)
11 * WBMP (builtin)
12 * WebP via libwebp
13 * PNG via libpng

15 libjpeg-turbo (recommended)
16 libJpeg-
17 Does not include JPEG2000

19 * HEIF via libheif - This includes AVIF read support if your system's
20 libheif has AV1 decoding.
21 * TIFF via libtiff

24 GD is commonly used to generate charts, graphics, thumbnails, and most
25 anything else, on the fly. It is lite weight and fits usages like web
26 development, embemdedded, or any other usages you may need.
28 It supports transparency, blending, images transformations and various
29 filters. Its design allows the additions of custom features in a very
30 friendly manner.
