InShape *.IIM
8 bytes file ID ["IS_IMAGE"]
1 word type [0 = 1 plane, 1 = 8 planes, 4 = 24 planes, 5 = 32 planes]
1 word ? (appears to be planes, but inconsistent)
1 word image width in pixels
1 word image height in pixels
--------
16 bytes total for header
?? Image data:
1 plane is monochrome, width assumed to be rounded up to the nearest byte
8 planes is 256 level grayscale, where 0 = black and 255 = white
24 planes is true-color, RGB format, 3 bytes per pixel in R, G, B order
32 planes is true-color, RGB format with alpha, 4 bytes per pixel in A, R, G, B order
From the InShape website:
The IIM format has several variants:
- Duochrome.
- 256 Grayscale.
- 24 bit (16 million colors).
- 32 bit (24 bit alpha channel for mask).
