- 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 32-bit grayscale images.
If the image has a LUT and you want to work on the image data, set RasterImage.UseLookupTable to false. Then, after calling the method, reset the UselookupTable property to true, as follows:
rasterImage.UseLookupTable = false; Method(rasterImage); rasterImage.UseLookupTable = true;For more information, refer to Correcting Colors.
