Remarks

  • If the image has a region, the effect will be applied on the region only.
  • For an example, the following figure shows a image before the effect is applied.

    The following figure shows the same image after the effect has been applied.

  • 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.
For more information, refer to Correcting Colors.
