Tilman Hausherr commented on PDFBOX-5897:
-----------------------------------------
It turns out it is possible but it's dirty:
{code}
doc.getDocumentCatalog().getCOSObject().setItem(COSName.VERSION,
COSName.getPDFName("1.3"));
doc.getDocument().setVersion(1.3f);
{code}
> Can't create an empty PDDocument with specific PDF version

> Key: PDFBOX-5897
> URL: https://issues.apache.org/jira/browse/PDFBOX-5897
> Project: PDFBox
> Issue Type: Improvement
> Affects Versions: 3.0.3 PDFBox
> Reporter: Asger Hautop Drewsen
> Priority: Major
> Attachments: empty.pdf
>
>
> Currently `new PDDocument()` creates a version 1.4 PDF.
> Changing the version afterwards with `.setVersion(...)` only works if the
> version is greater than or equal to 1.4.
> It would be nice if there was a constructor for `PDDocument` where you could
> specify the PDF version especially since you can't downgrade it to a lower
> version after it has been created.
