Description The XIMG (Extended GEM Bit Image) image format is more developed version of GEM raster Image [x-fmt/159] which allows for standardised verison of storing colour palettes.

The GEM raster format (also known as GEM VDI Bit Image; GEM Bit Image; GEM Image; GEM Bitmap; or IMG) is an image format native to the Graphical Environment Manager (GEM) operating system and developed at Digital Research. The format was used by GEM Paint and Ventura Publisher, and by a variety of Atari ST software.
