Obviously the text doesn't appear unless you put it there. djdjdj wrote: > However, if I look at the digital signature signing information it > contains all of the information of the signer.

Actually you can write anything into that layer. iText writes a text containing signer certificate, signing date, reason and location. You may instead write a weather forecast there. If you want to write something like iText does, you might want to be inspired by the code in PdfSignatureAppearance.getAppearance(). The signature signing information stem from the signature dictionary referenced from the signature field, not its appearance. djdjdj wrote: > Does the entire appearance have to be rebuilt from scratch at that point? > Seems pretty silly since, atleast from a code standpoint, methods dealing > with resizing are accessible from sap.Image the same as if you are > declaring a new itextsharp.text Image object. Either you use the layout the way iText produces it all by itself or you create your own, you have to decide.
