I didn't know you were talking about a digital signature. I had just done a project where I had to put a gif file with a signature (an image not a digital signature) on a PDF. If we're talking about a digital signature, please have a look at these examples: http://1t3xt.info/examples/browse/?page=example&id=251 http://1t3xt.info/examples/browse/?page=example&id=252 The first example adds an unsigned signature field; the second one replaces this empty field by a digital signature. You don't have to worry about coordinates if you do it this way. br, Bruno ------------------------------------------------------------------------- This SF.net email is sponsored by: Microsoft Defy all challenges.
