[edit] Identification
.pix files begin with ASCII "PIXT".
[edit] Format
1 long file ID 'PIXT'
1 word version, $0001 or $0002
1 byte type, 0 to 2 depending on number of planes, see below
1 byte number of planes
1 word xres (always a multiple of 16)
1 word yres
1 word unknown
1 word unknown (version $0002 only)
--------------
14 or 16 bytes total for header
3*n bytes palette, only for bit depths 2, 4, 8
3 bytes per entry in RGB order (0-255)
???? bytes image data:
bit depth 1
type = 1, planar
bit depths 2, 4, 8
type = 0, chunky
type = 1, planar
bit depth 16 is always chunky:
type = 0, xRRRRRGGGGGBBBBB
type = 1, RRRRRGGGGGGBBBBB (Falcon)
type = 2, GGGBBBBBxRRRRRGG (word swapped)
bit depth 24 is always chunky:
type = 0, BGR
type = 1, RGB
bit depth 32 is always chunky:
type = 0, ARGB
