I agree that the mailing list can be useful. For instance: plenty of examples in the book have been written in answer to questions posted on the list. It's just that filtering out the "stupid questions" takes so much time that sometimes there is no time left to answer the genuine questions. Our teachers at school have taught us that there is no such thing as a stupid question, but experience has taught me that my teachers weren't always right. This being said, your question was not stupid, but I didn't understand it and therefore I didn't answer. What I did understand: You have a PDF with a single signature field. You want to manipulate this PDF so that the contents of the signature field are changed. I'm not sure if you're talking about an empty signature field; I assume that you're talking about a signed PDF. The way I see it, you should throw away the signature field, and sign the PDF anew (with a new signature). If that is the requirement, what is the problem? If that isn't the requirement, what do you want to do? Do you want to change the properties of a signature without invalidating the signature? Wouldn't that be forgery? If that were possible, wouldn't that be a serious vulnerability in PDF? ------------------------------------------------------------------------------ Beautiful is writing same markup.
