Remarks

  • This command is used to rebalance the colors in an image. It can be used to make color adjustments and corrections.
  • This command supports 1-, 2-, 3-, 4-, 5-, 6-, 7-, 8-, 24-, 48- and 64-bit images and can support regions for 24-, 48- and 64-bit images. If the image has a region, the effect will be applied on the region only.
  • This command does not support signed data images.
  • This command does not support 32-bit grayscale images.
