> Subject: [iText-questions] PdfGraphics2D save/restore problem in
> Acrobat 4
>
> 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?
