Remarks

(Raster Pro and above toolkits) Adds shadows to the bitmap.

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

Support for 12 and 16-bit grayscale and 48 and 64-bit color images is available only in the Document/Medical toolkits.

This method does not support signed data images. It returns the error code ERROR_SIGNED_DATA_NOT_SUPPORTED if a signed data image is passed to this method.
