Hi,
Yeah it working like a charm ! I just add those lines just before calling
doc.addSignature(signature, this, options);
for(PDField pdField : doc.getDocumentCatalog().getAcroForm().getFields()) {
if (pdField instanceof PDSignatureField) {
if (pdField.getPartialName().equals("Zone de Signature 3")) {
pdField.getWidgets().get(0).setHidden(true);
( (PDSignatureField)pdField ).setValue(signature);
pdField.getWidgets().get(0).setHidden(false);
break;
}
}
}
doc.addSignature(signature, this, options);
I used setHidden() in order to fool the PDSignatureField.constructAppearances()
function and avoid the NotImplementedException. I think it's working because
the appearances is already build so there is no needs to build it again.
If you want to try this, just put those lines in the
CreateVisibleSignature.java example class.
I also wrote my own buildSignature() function in order to put the visible
signature field where and with the size I need.
Cyril.

if you are looking for specific setters/getters/methods please let me know. I
might be able to point you to the 2.0 alternative.
