The SharpenImage() method says: % SharpenImage() sharpens the image. We convolve the image with a Gaussian % operator of the given radius and standard deviation (sigma). For % reasonable results, radius should be larger than sigma. Use a radius of 0 % and SharpenImage() selects a suitable radius for you. % % Using a separable kernel would be faster, but the negative weights cancel % out on the corners of the kernel producing often undesirable ringing in the % filtered result; this can be avoided by using a 2D gaussian shaped image % sharpening kernel instead. _______________________________________________ Magick-users mailing list [email protected] http://studio.imagemagick.org/mailman/listinfo/magick-users
