-adaptive-resize geometry, adaptively resize image with data dependent triangulation. -adaptive-sharpen geometry, adaptively sharpen pixels; increase effect. Due to recommendations for using adaptive-sharpen ( discourse-server =1&t=) I decided to give it a try. -adaptive-blur -adaptive-sharpen -black-threshold -clut (when mapping greyscale CLUT image to alpha channel if set by -channels) -colors for gray colorspace.

ImageMagick Sharpen Resized Images |
Post any defects you find in the released or beta versions of the ImageMagick software here. Include the ImageMagick version, OS, and any command-line required to reproduce the problem.
Imagemagifk a patch for a bug? Due to recommendations for using adaptive-sharpen http: Select all convert source.
However, going back to my post in the link you referenced, when I tried 0x5 and 15×5 since that old post indicated xharpen the radius needed to be specifiedI found that neither produce imagemagcik change in the image. I am not sure if this is a reasonable test image or not for -adaptive-sharpen.
I also tried using the lena image as well with the same zero difference from compare with the original. I tried a couple of different values 10×1.
Or do you have any two settings that result in two different imafemagick In my earlier post on the link you provided, I had found that if one specifies a radius typically 3 times the sigma value that it did make a difference.
Now even that does not work for me. But again, this is an adaptive script and it may be image dependent. However, I would have expected to see some difference and not a perfect compare value of zero.
It’s not just that I can’t see sharpening differences, but the files are identical, sharpened vs. Everything else mogrify-wise works. I’m not sure whether it’s expected or what not, but seemed worth noting.
I can’t run 6. I guess I’ll wait for next rev – thanks muchly. Perhaps one of your delegates needs updating if installing from source.
If on Windows, I found this site of old binaries http: I am installing Windows binaries. Without knowing when the ICC problem was introduced, I’d not know which earlier rev to choose, without trying each one I mean. But I need working ICC profiles, not adaptive sharpening, yet, so 6.

ICC profiles are not working correctly in 6. Dunno if imagemagicck all cases or just some cases If someone does not report it properly, then it will not get fixed.
Please start a new topic on the Bugs forum to report this properly.
