Frankly, I don't understand the convolution matrix code. >Why does it take 50 samples and then average them? Is this significant? even if i am not a developer i may assure you that consider the neighboring pixels (that is what convolution matrix are for ) is VERY significant, and sure that may explain well why result look simultaneously more contrasted and smoother. i think you should really give a look to what convolution matrix may do -- photocomix (via gimpusers.com) _______________________________________________ Gimp-developer mailing list Gimp-developer@xxxxxxxxxxxxxxxxxxxxxx https://lists.XCF.Berkeley.EDU/mailman/listinfo/gimp-developer
