Hey Folks,
When I call 'sample' on a node from inside a knobChanged callback in
python, it only returns new values occasionally. I'm printing out the x,y
sample location that I'm getting out of the position knob, and it's
changing smoothly - but the rgb values that I'm getting returned from my
sample calls don't change smoothly. I'm assuming this an evaluation
problem. Here's my sampling code:
scolR = groupIdImage.sample( 'red', origXY[0], origXY[1] )
scolG = groupIdImage.sample( 'green', origXY[0], origXY[1] )
scolB = groupIdImage.sample( 'blue', origXY[0], origXY[1] )
Does anybody have success with this sort of thing in python callbacks?
Chris

I think this situation absolutely requires that a really futile and stupid
gesture be done on somebody's part. And we're just the guys to do it.
