In PDFBox 1.8.10, I sign the form with code very similar to the CreateVisibleSignature.java example.
This seems to work well enough, however when I fill out the form FIRST using code like the below, it breaks the signature; when I click on the signature I see error message "Error during signature verification, Unexpected byte range values defining scope of signed data., Details: The signature byte range is invalid." This is how I set field on my form fields: PDTextbox field = (PDTextbox) acroForm.getField( fieldName ); field.setValue(fieldValue); pdfDocument.save(pdfFilePath); I get the impression I have to associate every applicable field with this signature, but just a guess. Note: - My form has 8 signatures and various fields to be filled out by each. - I would prefer to have all fields and signature lines locked on the PDF beforehand and then just to set them with my code, but I believe with this version you can only place a signature and not fill out an existing signature field, correct? I definitely feel like I'm missing something, any help is appreciated. -----Original Message----- From: Tilman Hausherr <thaush...@t-online.de> Sent: December 11, 2019 1:46 PM To: users@pdfbox.apache.org Subject: Re: Page boxes differ between Acrobat and PDFBox Ouch, I've known about this, but put it on low priority because I've never seen such a file before. I've opened https://issues.apache.org/jira/browse/PDFBOX-4706 I'm not yet sure what to do, but COSName.USER_UNIT is the minimum. Getter/Setter probably too.
