This command applies a convolution matrix upon each color component and then combines the results in order to add shadows.
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.
