A rectangle, expressed in points with the origin at the bottom left corner, defining the visible region of default user space. When the page is displayed or printed, its contents are to be clipped (cropped) to this rectangle and then imposed on the output medium in some implementation-defined manner.
If the CropBox is a null reference, please use the MediaBox. You cannot set this entry if any [Visual]Underlay or [Visual]Overlay is instanciated.
