#IPAS needed
Yo,
I just uploaded an IXP to do that. It took me a good 10 minutes to write, so
don't get spoiled. It has three sliders (for each color component). The values
are from 0 to 255. Leave it a 255 and it won't change anything. Move to 128 and
all values above that will be cropped down to 128. The routine has Alpha
support so you can specify "areas" to apply if that makes any sense (it was
there already).
I called CROP_I.IXP (uploaded as CROP.ZIP) and it should be available along
with the Yost Chowder (I will pay for that) later today or tomorrow morning.
