13 ===========
14
15 This is a grey-scale image with a depth of 12 bits per pixel, but with
16 pixels from 2 sources interleaved and bit-packed. Each pixel is stored
17 in a 24-bit word in the little-endian order. On a little-endian machine
18 these pixels can be deinterlaced using

26 **Bit-packed representation.**
27 pixels cross the byte boundary and have a ratio of 3 bytes for each
28 interleaved pixel.
