DGI (Digi-Pic)

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

Digi-Pic is sort of a PC graphics software tech demo. It was created by Basi Angulo and Dion Kraft.

There were apparently at least two Digi-Pic releases. DGI format is associated with the second release.

Format details
Images are 640×400 pixels, 2 bits per pixel. The image is stored as four 320×200 images, each of which is interlaced. File size is 64008 bytes. The 8 extra bytes are located at offset 32000.

It's not clear if there's a canonical color scheme, but Turbo DiGI uses the CGA black/green/red/brown palette. DGIMAC.EXE converts .DGI images into monochrome by ignoring every second bit of image.

Identification
Bytes appear at offset 32000. The file size is normally exactly 64008 bytes.
