HI ,
I got this exception what are the situation came this exception :
com.lowagie.text.exceptions.IllegalPdfSyntaxException: Unbalanced
save/restore state operators
give me sugetion how to debug *itext* code when the have face this
type of exceptions
I searched In but not find suitable answer.
Search not further, just read the error message: you have unbalanced
save/restore state operators.
In other words, somewhere you have used the method saveState() without
using restoreState().
Or you have used restoreState() without using saveState().
Or maybe you have something like:
cb.saveState();
document.newPage();
cb.restoreState();
In older versions of iText, we allowed developers to write PDF syntax
any which way they want.
Unfortunately, when you give this power to developers who didn't read
and understand ISO-32000-1 (the standard you've probably read whilst
searching for a suitable answer), you end up with PDFs that are corrupt.
That's why we took away a little bit of that power. In order to make
iText more "fool-proof", we now throw an exception when a developer
doesn't respect the q/Q-rule.
