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