DGI (Digi-Pic)

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 01 04 00 00 00 00 00 00 appear at offset 32000. The file size is normally exactly 64008 bytes.
