DGI is a raster graphics format apparently associated with something called Digi-Pic.

Images are 640x400. File size is 64 008 Bytes. File size and presence of colors suggest 2 bpp. Image is stored in 8 planes. Each plane is 640x100 mono. 8 planes * 640*100 = 64 000 Bytes. The 8 extra bytes are located at offset 32000 (but why?).

DGIMAC.EXE converts .DGI images into monochrome by ignoring every second bit of image. TURBODGI.ZIP displays image in 3 colors (gray, black, red).
