public void sanityCheck()
Checks for any dangling state: Mismatched save/restore state, begin/end text, begin/end layer, or begin/end marked content sequence. If found, this function will throw. This function is called automatically during a reset() (from Document.newPage() for example), and before writing itself out in toPdf(). One possible cause: not calling myPdfGraphics2D.dispose() will leave dangling saveState() calls.

Throws:
IllegalPdfSyntaxException - (a runtime exception)
Since:
2.1.6
