Can you not just change the return value depending on the y position
in the filter? Something like:
return y<pos1?
(formula 1) :
y<pos2?
(formula 2):
y<pos3?
(formula 3) : (formula 4);
At least that's how I tend to do this kind of thing.. although I
seem to remember conditionals being somewhat more limited in core
image, so you have to plan a bit.
He was wanting to avoid the ternary operator, since it can force the filter to run in software mode. :/
That said, At this point, I'm all for "Just pick a stinking plan already" and then profile to see what needs to be accelerated. The Perfect is the enemy of the Good.
