p.s. [saturate 1( and [saturate 0( _do_ work with [pix_gain], however
not with [pix_offset], so maybe you could just copy the behaviour
from pix_gain directly to pix_offset?

i found a workaround. if i insert a [pix_rgba] object before
[pix_offset], it will work (doesn't work without your fix, so thanks
a lot for it!). strangely the alpha channel is the first, followed by
red, green, blue, so it's really ARGB not RGBA ...
's fine for me know!

hi,
how can i limit the RGB channels of a film that goes through
[pix_film] - [pix_buf] - [pix_gain] - [pix_offset]. right now i
get colour wrapping from gain + offset but i want to limit the
colours. say i scale down the red channel and i add an offset to the
green channel, i don't want

The PPC code
The colors should not wrap around. What CPU are you using?
