This patch removes the support for copy and paste protection from pdf documents and is intended for use with xpdf version 0.93. The original patch did not work on version 0.93 (pdftotext.cc failed), but this one should.


To apply:

cd xpdf-0.93/
patch -p1 < xpdf-0.93-ro-remove.patch

diff -ruN xpdf-0.93/xpdf/pdftotext.cc xpdf-ro-removed-0.93/xpdf/pdftotext.cc
