title: Using PDFTron in Python, remove all image elements from a PDF with given size characteristics
body: <p>I'm trying to remove a large number of very small images from a series of PDF documents using the awesome looking PDFTron library for Python.  Basically I want to create a new PDF by going over each element in an existing PDF file and copying the ones that meet a certain size criteria to the new PDF in the same position.</p>
  
  <p>Can someone guide me to PDFTron documentation specifically for Python to help me accomplish this?  Or provide a sample script that checks for image size?  I think I can do the rest (emphasis on think).  The documentation available on the PDFTron website is not specifically for Python, hard to look up what I need...</p>
