How to extract only an area of a PDF page and place it in a fresh PDF file?

Q: I am looking for a sample program which can demonstrate how to copy
area of a PDF and then place the copied area in to a new PDF file
A: As a starting point you may want to take a look at ElementEdit
sample project (

The sample shows how to remove images and change text color in PDF,
however you can tweak the code so that only element within given
region/rectangle are copied on the target page. To obtain a bounding
box for an element use element.GetBBox(rect). To test for rectangle
intersection use rect.IntersectRect(r1, r2).
