Extracts individual slices from a radiographic scanned film. This method is available in the Imaging Pro and above toolkits.

.This command is designed to extract the individual slices from radiographic scanned film. The image below shows an example of these radiographic images before and after applying the SliceCommand where we use the output data to draw a white line around each separate slice.
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.
This event will draw a new region around the newly found slice.
