Where is the existing image? If it's not already in the pdf and it's not on file, then where?

As Bruno said, the problem now is how to get the indirect reference...
But what i need is not to get the image (or a copy) but to bind to this image : add the digital signature to the PDF and link the digital signature to an existing image.

Any idea ?


Philippe.

Yes, it's possible. See Image.getInstance(PRIndirectReference ref). I'm not sure if it made it into 1.4.1 or if it's only in the CVS.
