Leadtools.ImageProcessing Namespace : GrayscaleCommand Class




Converts a 1-, 4-, 8-, 16-, 24-, or 32-bit image to an 8-bit, 12-bit, or 16-bit grayscale image.

Example

This example will load a 24-bit image then convert it to a grayscale image with 8, 12 and 16 bits/pixel

Remarks

Support for 12 and 16-bit grayscale images is available only in the Document/Medical Imaging editions.

The resulting image can be an 8-bit, 12-bit, or 16-bit grayscale image. Once the function is complete, the RasterImage.GrayscaleMode property will indicate the type of grayscale image.

When converting to 12-bit or 16-bit grayscale, the RasterImage.GetLookupTable is not used. When converting to 8-bit grayscale, the RasterImage.GetLookupTable is used to get the RGB for each input pixel. The grayscale value corresponding to that RGB triple is used in the destination image.

This method does not support signed images.
