Are these built in CI filters or ones which you have written?
Sounds like a missing ROI function.
This is also plausible. My only "driver bug" indicator was his
statement:
CI seems to glitch with 32bit colour + high resolution, tiling the
image might help. It seems that if I use an image > 1024 pixels and
run a CI Filter that samples at an offset, it can't sample to the
right of the 1024pixel boundary for a destination to the left. I
might have to implement some kind of tiling to get around that..
If the behaviour is different in 32bit mode from 8bit mode, or if
the image dimensions affect sampling behaviour, an ROI problem
should still present itself in those cases (in my opinion -- there
are of course implementation details that may negate that).
Chris, can you supply an example composition with a filter that
exhibits said problem, so others can test against it?
