Thank you for your answer, Herr Hausherr.

I was asking because there is a BoundingBox class and the documentation 
states: "T*his is an implementation of a bounding box. This was 
originally written for the AMF parser.*"  Additionally, the PDPage class 
has a getBBox() method, so I was curious to the differences between 
MediaBox, BoundingBox, CropBox and BleedBox.  Is this something I can 
find in the PDF specification document?

Thanks again for your help.

Jorge
