Re: Compositing issues with output from Quartz Patch



As far as I'm aware they do. Without staring at the code in huge detail I'd base that off of the observation that it works on Leopard just fine (the Tiger box is also an Intel box, just like the 10.5 machine).

I would have thought that if it were an ordering issue I'd see the same incorrect values on both system versions.
They are certainly not far enough askew to be thinking that it's something like interpreting ARGB as BGRA for example.


I've put links to two sample videos. One for leopard and the same code running on Tiger.

The original RGB values of the blue of a highlited row in a table is 56,117,215. After grabbing and turning into a CIImage via a CGBitmapContext, that turns into 116,179,239. Once it's composited back onto the original frame it has become 170,217,250.

I feel I'm missing something quite basic here... can't for the life of me spot it at the moment.
Any tips/suggestions that I might try?

Do all the parties agree on the byte order of the pixels?
