Legacy ImageMagick Discussions Archive

I'm aware that I can use "+dither -colors x" and get an image with x colors that is as close to the original image's colors as possible. But I can't, for example, use "-ordered-dither o8x8 -colors x" and achieve the same effects. It appears to me that "-ordered-dither" use 'posterized' color maps, and does not take account in the original image's palette, and while I can change the posterize level, I can't create an ordered dither that picks colors based on the current image contents.

If there's any way to achieve my goal please tell me, that would be extremely helpful.

Please always provide your ImageMagick version and platform/OS when asking questions. Also please try to make your question relevant to the topic and not just "please help me".

Best I can suggest is http://www.imagemagick.org/Usage/quanti ... one_offset

Can you link to any examples of input images and dithered results?
