PDF-UA-compliance error by creating of signature fields in pdfbox version higher than 2.0.31
Hello pdfbox community,
since Apache PDFBox version 2.0.31, we are not able to generate PDF-UA-compliant signature fields. We are attaching a code snippet that we use to create visible signature fields. Please let me know what I need to change in this code so that the PDF document remains PDF-UA-compliant. We verify PDF-UA compliance by using the PAC APP ( https://www.axes4.com/de )
Two sample documents are attached to this email: original and result with signatures fields.
/** used with pdfbox 2.0.36 */
public static void main(String[] args)
{
File inputFile = new File("PDF_UA_original.pdf");
File outputFile = new File("result.pdf");
float xPos = 50;
float yStart = 600;
float width = 200;
float high = 50;
float distance = 70;
try (PDDocument doc = PDDocument.load(inputFile))
{
PDDocumentCatalog documentCatalog = doc.getDocumentCatalog();
PDPageTree allPages = documentCatalog.getPages();
PDPage pdPage = allPages.get(0);
PDAcroForm acroForm = documentCatalog.getAcroForm();
if (acroForm == null)
{
acroForm = new PDAcroForm(doc);
documentCatalog.setAcroForm(acroForm);
}
for ( int i = 0 ; i < 4 ; i++ )
{
PDSignatureField pdSignatureField = new PDSignatureField(acroForm);
pdSignatureField.setPartialName("SigField_" + UUID.randomUUID().toString());
pdSignatureField.setAlternateFieldName("Alt_" + pdSignatureField.getPartialName());
float currentY = yStart - (i * distance);
PDRectangle rectangle = new PDRectangle(xPos, currentY, width, high);
PDAnnotationWidget widget = pdSignatureField.getWidgets().get(0);
widget.setRectangle(rectangle);
PDAppearanceDictionary pdAppearanceDictionary = new PDAppearanceDictionary();
PDAppearanceStream appearanceStream = new PDAppearanceStream(doc);
pdAppearanceDictionary.setNormalAppearance(appearanceStream);
widget.setAppearance(pdAppearanceDictionary);
widget.setPage(pdPage);
acroForm.getFields().add(pdSignatureField);
pdPage.getAnnotations().add(widget);
pdPage.getCOSObject().setNeedToBeUpdated(true);
doc.getSignatureFields().add(pdSignatureField);
}
doc.save( outputFile );
}
catch (Exception e)
{
e.printStackTrace();
}
}
Best regards,
Thank you very much for your support

Re: PDF-UA-compliance error by creating of signature fields in pdfbox version higher than 2.0.31
Posted by Tilman Hausherr <TH...@t-online.de>.
Files are here:
https://drive.google.com/drive/folders/1jo4g-ElaMB15Hh1lW9B04DxWKSXramvL?usp=sharing
The error is "widget annotation not nested inside a Form structure element".
What I suspect: each annotation needs a /StructParent number, and these
numbers must be in the Parent tree and in the K tree. The best would be
to have a compliant file so that we can see what needs to be done.
I did something like that here:
https://stackoverflow.com/questions/79083813/how-to-add-the-annotation-tag-in-tagged-pdf-using-pdfbox
However your case is even more difficult, you have to do it while
signing and make sure that the changes are included in the incremental save.

Hi,
Please upload the files to a sharehoster that doesn't require registration.
Are you saying that it did work with 2.0.30 ? If so, then include these as well.
