ImagingGif (at line 49)
GIF was (and is still used) popular format for storing images supporting multiple images per file and single color transparency. Pixel format is 8 bit indexed where each image frame can have its own color palette. GIF uses lossless LZW compression (patent expired few years ago). Imaging can load and save all GIFs with all frames and supports transparency. Imaging can load just raw ifIndex8 frames or also animate them in ifA8R8G8B8 format. See ImagingGIFLoadAnimated option.
