We are also receiving many PDFs from our customers with patterns in the layout
which explode the SWF filesize and cause flash player to become unresponsive.
I would very much appreciate pattern detection and conversion to bitmap, but
this is of course much easier asked then implemented.
Anyone have a clue how could these patterns could be detected? Are these even
defined in the PDF files as patterns?
