What are the differences between PDPageGetMediaBox and PDPageGetSize?

The PDPageGetSize() interface was created first to return PDF page size, returning it as a simple width and depth.

These interfaces were added later to provide more precise definitions of the page added to the PDF document:

• PDPageGetMediaBox()
• PDPageGetCropBox()
• PDPageGetBox()

At this point both PDPageGetMediaBox and PDPageGetSize provide the same values.

The bounding box returned by PDPageGetMediaBox() should have right – left = width and top – bottom = depth of the PDPageGetSize() interface.
