Hi Bruno/Paulo (or mailing list users whom it may concern):
As people are not to keen to be contacted directly, I've had to post this here,
so apologies if it's wrong in advance (as I'm not registered with the mailing
list yet). This is not a question, I'm merely trying to be helpful with people
getting error's with 'unbalanced states' trying to run the example program
supplied.
I was looking at your example for page numbering and total pages example (as
I'll be looking to put page numbering + total pages, mid page rather than in
the footer), and the code example shown is seemingly incorrect (sorry if this
is not the case).
To get it running I had to add in an extra cb.restoreState() into an else block
(as shown just above the cb.sanityCheck() ):-
// starting on page 3, a watermark with an Image that is made
transparent
if (writer.getPageNumber() >= 3) {
cb.setGState(gstate);
cb.setColorFill(Color.red);
cb.beginText();
cb.setFontAndSize(helv, 48);
cb.showTextAligned(Element.ALIGN_CENTER, "Watermark Opacity " +
writer.getPageNumber(), document.getPageSize().getWidth() / 2,
document.getPageSize().getHeight() / 2, 45);
cb.endText();
try {
cb.addImage(headerImage, headerImage.getWidth(), 0, 0,
headerImage.getHeight(), 440, 80);
}
catch(Exception e) {
throw new ExceptionConverter(e);
}
cb.restoreState();
} else {
cb.restoreState();
}
cb.sanityCheck();
}
All the best :)
