This evening I've been trying to find out what makes the RGB values are so inaccurate, and quiet a bit sometimes and I've come to the conclusion that this is no simple rounding errors. I've also tried to load both premultiplied and non-premultiplied pictures but as this image has no alpha it didn't make any difference whatsoever.
Trying to come up with what it could be, I went through the chain which was the matte standard shader to see if there's any gamma correction or something similar going on. Nothing.
Now I'm kind of stuck why Cerberus gives me these strange numbers? If you plot anything yourself there's absolutely never any problems in reading every bit correctly. But it can't handle anything that have been loaded?
Looking at the testchart..
000000 becomes 00000, fcfcfc becomes fcfcfc which is fine of course
but then we have 7070fc that shows up as 7f58ff
and 208800 as 009107 etc
