Thanks for the information.
I testdrive the PDFread. It does not seem to provide the file split results I am looking for, i.e., cut the file to 2*2 pieces. I will follow and see what they can get.

The creator of PDFLRF is no longer active and on top of that the developer never realeased the code.
There is a tool PDFRead that is currently being developed. They are working on the very algorithm you spoke of. See the PDFRead thead.
