Thanks for the previous answer! There goes another question:
is there any chance to build a PDF/A signed with a visible signature and that i could manage with the Adobe Reader to 'show/not show' the signature over the images/text? As i see that problem, if i create a PDF/A with a signature there are only 2 possibilities: - the PDF signature is always visible - the PDF signature is always invisble. Am I right? thanks in advance! Josep Maria Leonard Rosenthol-3 wrote: > > iText only supports PDF/A-1, which does not support layers/OCGs.
