DESCRIPTIONThis program alters a PDF document to add a solid background color behind the page contents.
CAVEATSSome PDF creation programs assume a white background and draw bogus white rectangles all over the screen that you usually cannot see. If your PDF has such rectangles, you can sometimes fix it, but it is a pain. The best recommendation is to recreate the original PDF using a smarter library, if possible. Alternatively, you can contact Clotho Advanced Media for a commercial solution to this problem.
