I suppose I should clarify; I was not bemoaning the lack of support or generosity, I was stating the situation as it had occurred to that point - one gentleman had offered support (and through no fault of his own) added more questions than answers. I did not mean to come off as impatient, I am always thankful and never question the delivery of free knowledge. ________________________________________ From: Andreas Lehmkuehler [[email protected]] Sent: Sunday, May 20, 2012 7:02 AM To: [email protected] Subject: Re: PDFBox View Post-Read, Pre-Conversion Stream

It is not that easy. - the information you are looking for is part of the so called contentstream - that stream is processed within PDFStreamEngine#processStream [1] - the main test-processing is done in PDFStreamEngine#processEncodedText - the PDF-operator -> ProcessOperator mapping can be found here [2] - the class TestPosition doesn't have any onformation about text features like superscript - you might have a look at the pdf specs [3] > I am using the .NET port of pdfBox and I would appreciate some > examples (preferably VB or C#) but Java was my first language and > I'm sure I can knock the dust off of my knowledge. As it is complicated enough to implement this stuff in java, I guess there won't be any approaches in VB or C#.
