0012 Description
0013 ===========
0014
0015 This is a grey-scale image with a depth of 12 bits per pixel, but with
0016 pixels from 2 sources interleaved and bit-packed. Each pixel is stored
0017 in a 24-bit word in the little-endian order. On a little-endian machine
0018 these pixels can be deinterlaced using
0019
0020 .. code-block:: c
0021
0022 __u8 *buf;
0023 left0 = 0xfff & *(__u16 *)buf;
0024 right0 = *(__u16 *)(buf + 1) >> 4;
0025
0026 **Bit-packed representation.**
0027 pixels cross the byte boundary and have a ratio of 3 bytes for each
0028 interleaved pixel.
