Also, ensure no false positives when determining DNG bayer images, by
setting them in tiff.c instead of relying on a heuristic. There's no

Dissenting opinion: PTS is the important thing, and there are lot of

DTS is just an annoying technical tidbit that goes with PTS.

I assume you're talking about the "if (!s->bayer || mb_x) {"... code.
1) The special case there happens for the first line, not row like the
code you mentioned.
2) The loop is "width*height*component" in this order, so I'm not sure
how I would something for the first line outside.
3) It depends on
The data the marker contains is only 2 bytes and they're 0x in the
samples above. I don't know what they're for.
