Hi there,since itext release 2.0.3 itext creates a signature appearance even if the signature is an invisible one.
The code modification has been done with revision 2741 in file /trunk/src/com/lowagie/text/pdf/PdfSignatureAppearance.java/ <http://itext.svn.sourceforge.net/viewvc/itext/trunk/src/com/lowagie/text/pdf/PdfSignatureAppearance.java?view=log&pathrev=2741>. The corresponding svn comment is "always create an appearance even if it's an invisible signature".
Can anybody of you tell me the reason for this?We are currently dealing with the following problem: We add an invisible signature to a pdf document. After that the PDF document cannot be printed with (at least) Adobe Acrobot 7 correctly (the first page is printed correctly, subsequent pages contain only a few huge letters instead of the actual contents).
We have done some tests with modifying the itext source, and the tests confirm that the printing problem is caused by adding the signature appearence for the invisible signature. As soon as the signature appearance si not added, printing works fine again.
I can provide test samples if this is of use, but since they are real life examples from one of our customers I do not want to post them on the mailing list.
Thanks in advance, Gregor
