This command duplicates the original image palette, if one is required in the new image.
This command uses image coordinates to specify the area to be copied. Therefore, you must account for the RasterImage.ViewPerspective of the image. For information about image coordinates, refer to Accounting for View Perspective.
If a region is defined for the source image, the region is also copied, and the region is clipped if necessary.
The CopyRectangleCommand command works by creating a new image in the DestinationImage property from the image passed to the RasterCommand.Run method.
