The docs say that 16-bit deep frames contain the samples in the machine's<br>
|
|||
|
|
native byte order. Can I assume that they will always come in pairs, and<br>
|
|||
|
|
that they are sample-interleaved, not byte-interleaved?<br>
|
|||
|
|
<p>
|
|||
|
|
ie: on a little endian machine, would data look like this (where the first<br>
|
|||
|
|
character is R, G, or B, for the color of the sample and the second<br>
|
|||
|
|
character is 'L' or 'M' for the 'Least' or 'Most' significant byte):<br>
|
|||
|
|
<p>
|
|||
|
|
RL RM GL GM BL BM ...<br>
|
|||
|
|
<p>
|
|||
|
|
(which is what I am assuming)<br>
|
|||
|
|
<p>
|
|||
|
|
or can I expect some sort of nuttiness like<br>
|
|||
|
|
<p>
|
|||
|
|
RL GL BL RM GM BM<br>
|

|

Of course, I /realize/ that this would be a totally asinine way of<br>
|
|||
|
|
rendering the samples :-) But the spec leaves a /teensie/ bit of room for<br>
|
|||
|
|
asinine interpretation :-)<br>
