Hi again, the attachment with the screenshot didn't make it through, let me try an inline image.

August 2023 09:57 An: users@pdfbox.apache.org Betreff: AW: Adding annotations to PDFs - "expected a name object" CAUTION - External Sender Hi Tilman, thank you for the suggestion. Turns out, it's "Line" annotations. When I import <?xml version="1.0" encoding="UTF-8"?> <xfdf xmlns="http://ns.adobe.com/xfdf/"; xml:space="preserve"> <annots> <line width="3" color="#FF0000" caption-style="Inline" creationdate="D:20230526112815+02'00'" flags="print" start="1770.007568,1614.721436" end="1791.373535,1658.575195" date="D:20230526112815+02'00'" page="0" rect="1764.007568,1608.721436,1797.373535,1664.575195" subject="Linie" title="John Doe"> <popup flags="print,nozoom,norotate" open="no" page="0" rect="1780.690552,-92.000000,1964.690552,0.000000"/> </line> </annots> </xfdf> into either its original source or just a fresh, DIN A4 PDF with a single line of text created with PDFBox, Adobe Reader will complain. At this point, I switched from 2.0.29 to 3.0.0beta1 and the result was the same. In the resulting PDF, PDFDebugger shows what is in the attachment - an empty "NM" entry. I then tried to set either "Name" or "NM" (and ultimately both) in dictionary of the PDAnnotation to "Line" with PDAnnotation a = PDAnnotation.createAnnotation(xfdfAnnotation.getCOSObject()); a.getCOSObject().setItem(COSName.NM, new COSString("Line")); a.getCOSObject().setItem(COSName.NAME, new COSString("Line")); but while these values show up fine in PDFDebugger, [cid:image003.png@01D9C528.2A0E3C40] Adobe Reader will still complain. Would you happen to have more suggestions how I could work around this please ?

Then tell what names were in the xfdf file. Or make a screenshot in PDFDebugger of that annotation, without the text content.
