- This command replaces the specified color by adjusting value of hue, saturation and brightness. The value of the Fuzziness property of the ColorReplaceCommandColor class determines the range around each color where the pixels will be changed according to Hue, Saturation and Brightness.
- This command supports 12 and 16-bit grayscale and 48 and 64-bit color images. Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.
- This command does not support signed data images.
- This command does not support 32-bit grayscale images.
