retrieving unique colors?

[sdalu]

Is there a way to retrieve the list of unique colors used in an image?

Something like the unique-colors option of convert:

Code: Select all

convert IMG_1588.jpg  -colors 6 -unique-colors txt:-

Thanks

The UniqueColors() method returns an image with only unique colors. Use GetPixel() or GetPixels() to return the unique colors.
