Hello PDFbox Users!
Is it possible to get visible signature position on page of previously
signed PDF file?
I am using version 2.0.0 rc3.
Best Regards.
Go through all fields, find the ones that have the type "Sig", then
get the "Rect" element.
To see what I mean, start PDFDebugger, switch to "show internal
structure", and enter this:
Root/AcroForm/Fields/[0]/Rect/[0]
This may or may not be a signature field. If it isn't, try the other
fields.
Here's some code (error handling omitted):
PDDocument doc = PDDocument.load(new File("...."));
List<PDField> fields =
doc.getDocumentCatalog().getAcroForm().getFields();
for (PDField field : fields)
{
if ("Sig".equals(field.getFieldType()))
{
System.out.println(field.getWidgets().get(0).getRectangle());
}
}
doc.close();
running it with the file from
https://issues.apache.org/jira/browse/PDFBOX-2282 brings this output:
[68.52,567.84,245.64,626.04]
[68.88,391.56,246.12,449.76]
