In some cases, in the method
protected void basicTextShowGlyphs(PDGlyphs glyphs, float advance) throws CSException
of the CSCharacterParser class, the calculated glyphs' charRect (line 66) has a zero height, so it calls
onCharacterFound(glyphs, charRect) method with zero height charRect.
Is this can be an expected behaviour?
Sorry, I think I have posted it in a wrong section. Should have posted it to the 'help' section.
I'm sorry that i can't help you on this without further information.
There are a lot of bad behaved documents out there and most probably you have one of them. You should upload an example. In addition i can't see what code exactly causes the exception (CCharacterParser is abstract and has no throw statement).
