I commented before that I avoided using saveState() and restoreState() to
implement clipping in my PdfGraphics code because it generated invalid files
more often than not...now I know partially why. The following code uses the
PdfGraphics2D code in iText 0.91 to set a clipping region and draw a circle
in a template at the bottom of the page; the result displays fine in Acrobat
Reader 5 and GSview on Windows, and in xpdf and kghostview on Linux, but
produces "There was an error processing a page. Invalid restore." in Acrobat
Reader 4 on both platforms. If the PdfGraphics2D is created directly from
the base PdfContentByte instead of a template, it works fine even in Acrobat
4.
Could somebody more enlightened than I about the save/restore functionality
see if there's a way to avoid this problem? Or if it's an inherent bug in
Acrobat 4, at least document this in the FAQ?
