Returns the dimensions of the selected page's boundary rectangles.
The MediaBox represents the physical medium of the page.
The CropBox represents the visible region of the page, the contents will be clipped to this region.
The BleedBox is similar to the CropBox, but is the rectangle used in a production environment.
The TrimBox indicates the intended dimensions of the finished page after trimming, and the ArtBox defines the extent of the page's meaningful content as intended by the page's creator.
If the document does not have a CropBox but it does have a MediaBox then the CropBox will be the same as the MediaBox. If the document does not have any of the other boxes this function will return the values from the CropBox.
