Any area of a PDF that does not have content on it is "transparent" - there is no "background color".
And since iText doesn't actually render anything, I am not sure where the issue is.

IT is white be default, as far as I can tell. I use a component by PDFTron to render the pdf out to an image, and I want to be able to render to a PNG with transparency. Apparently their PDFNet SDK has such an option, which makes me think it must be possible, but I am using iText (well, iTextSharp) and not sure how to do this. Any advice?
