Fill an existing visible signature field with visual signature
Hello,
I am trying to sign a PDF document with an existing visible signature field. I wonder if this is possible to achieve that with PDFBox 2.0.0.
I also want to define the size of the visible signature generate with PDFBox.
Thank you.
Cyril Bremaud.
RE: Fill an existing visible signature field with visual signature
Posted by "BREMAUD, CYRIL" <cy...@atos.net>.
I actually make it happen with 1.8.x. It was a bit dirty because I had to write my own addSignature() function.
But now with 2.0.0 some setter disappear and the function addSignature() have radically changed.
At this point, I succeed to move and resize the PDRectangle of the visual signature but when I want to set the correct PDSignatureField an exception occurs.
Exception in thread "main" java.lang.UnsupportedOperationException: not implemented
at org.apache.pdfbox.pdmodel.interactive.form.PDSignatureField.constructAppearances(PDSignatureField.java:237)
at org.apache.pdfbox.pdmodel.interactive.form.PDTerminalField.applyChange(PDTerminalField.java:221)

For what it is worth, I tried and tried. I worked diligently to make this happen for a long time, and then when 1.8 transitioned to 2.0 I tried again. It never worked. It failed to work in a variety of different ways but I never got it to work.
For my own purposes I did not actually need a valid digital signature. I only needed the visual signature. The digital signature was not required it was just a nice to have. So I just use PDF drawing commands to draw the signature on the right place on the page using the location of the signature field rectangle as a guide.
That probably fixes no one's problem but my own, but if it does then I am glad to help.
But I can tell you that I put way more hours than I should into making this work and it never did.

RE: Fill an existing visible signature field with visual signature
Posted by "BREMAUD, CYRIL" <cy...@atos.net>.
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.

Please find attach a sample PDF document with empty visible signatures fields.
@Maruan
I succeed to set a new PDRectangle for my visible signature by writing a function based on PDFTemplateCreator.buildPDF(). But I'm still working on filling an empty already existing visible signature field.
Thank you.

the size of the signature can be set using the fields rectangle. As written before you would be on your own to generate a matching appearance stream.
