Remarks

  • This method 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.
  • If the image has a region, this method works only on the region. If the image does not have a region, this method works on the entire image.
  • This method does not support signed data images.
  • This command does not support 32-bit grayscale images.
