Description
Hi dev-team.
I just tried out one og your example codes and tried to adapt it a bit.
I´m trying to generate PDF Thumbnails. The Code works fine on 98% of all PDF files, but some crashes with an NPE just during opening them.
Just:
------------------------8<------------------------
Document document = new Document();
document.setFile(sFileName);
------------------------8<------------------------
leads into following NPE:
WARNING: Fatal error parsing PDF file stream.

Is there any possability to apend one or two PDF files to this ticket to give some files to check against?
kind regards
