PoDoFo is a library to work with the PDF file format. The name comes from the first letter of PDF (Portable Document Format). A few tools to work with PDF files are already included in the PoDoFo package. This repo is a fork of the code at http://svn.code.sf.net/p/podofo/code/podofo/trunk
It would be great if podofocrop could find trim marks and crop based on these marks.
See https://daubenmiresprinting.com/wp-content/uploads/2017/01/Printers-Marks-Diagram-636x703.jpg as example of crop/trim marks.
