We've worked with one of our customers to provide functionality to make sure that Adobe Reader always shows that the signed document is LTV enabled instead of the message that it isn't (which happens when you don't sign the document according to best practices).

Hi Bruno, I'll start saying Don't shoot the messenger :) The DSS part of this was only additional info. Note that the main question is that I produced this with iText 5.3.0. You will not find me as a registered customer of iText, as I'm not selling any software. I'm just a consultant. I'm creating the business for you, but I'm not your direct customer. I will read the linked document, thanks, and I will pass your message to the Commission. So what I hear you say is that the fact that 5.3.0 produces this result is not a bug, but a missing feature.

[iText-questions] Get text on particular layer

Is there a way to extract text from this particular layer only? I am familiar with programming, so I just wish to know if API has support for this? So far, I have been able to find only examples to add new layers for Pdf -files. Best Regards, Mika Mähönen Pori, Finland -- LogMeIn Rescue: Anywhere, Anytime Remote support for IT.

When you download iText from SourceForge, there's a zip with three jars. The code you need is in the xtra jar: com.itextpdf.text.pdf.ocg.OCGRemover With this class, you can remove layers from a PDF, keeping only the one you're interested in.
