I am trying to use the demo program to view and print files which display some fairly simple graphics normally in Adobe Reader, but which display very strangely in the WPViewPDF demo. Instead of a line drawings, there are solid-colored blocks (variously red and black; the latter having white arcs through them) which appear to correspond only to the areas where the lines should be drawn.
I do not know any details about how this pdf was created.
My first question is whether there I am seeing some limitation imposed on the demo.
