Not to be too dramatic, but none of the PDF examples and none of my old code works. Seems
to have been broken in 1.0.4 and up. Really any of the examples repro the problem.

working fine here.. is it possible you have another version of itext
somewhere in your classpath?

also try setting your sketchbook folder to a new (empty) folder, then
restart processing, then try a very simple example like:

size(200, 200, PDF, "output.pdf");
line(20, 20, 80, 80);
exit();

found it. the jar for the PostToWeb library has the BytePGraphicsPDF class in it. Once i removed
that lib all my PDF stuff started working.

sorry for the bother.
