public void CropPage( int left, int right, int top, int bottom )
Public Sub CropPage ( left As Integer, right As Integer, top As Integer, bottom As Integer )
This page is cropped from the original edges of the pages (defined by CropBoxOriginal) inward. That is, if CropPage(100, 100, 100, 100) is called and then CropPage(50, 50, 50, 50) is called, it is as if only CropPage(50, 50, 50, 50) was called. The two operations are not additive.
