You are mixing different things making it very hard to answer your question. Adding the signature as a visible field or not, is one thing. Making fields in a form read only is another thing. Also, are you talking about author or recipient signatures? If you're talking about author signatures, the PDF reference let's you choose between the following options: 1 No changes to the document are permitted; any change to the document invalidates the signature. 2 Permitted changes are filling in forms, instantiating page templates, and signing; other changes invalidate the signature. 3 Permitted changes are the same as for 2, as well as annotation creation, deletion, and modification; other changes invalidate the signature. That's different from making fields read only (which is also possible with iText). In other words: your question sounds like "how many days?" We can only answer with a counter question: "do you mean how many days are there in a month? in a week? in a year?" -- This answer is provided by 1T3XT BVBA http://www.1t3xt.com/ - http://www.1t3xt.info ------------------------------------------------------------------------------ Apps built with the Adobe(R) Flex(R) framework and Flex Builder(TM) are powering Web 2.0 with engaging, cross-platform capabilities.
