MH commented on PDFBOX-854:
---------------------------
I searched for some bug reports concerning coordinates and found e.g.
PDFBOX-828 from 30.09.2010. So I reveretd pdfbox/fontbox/jempbox back to the
1.2.1 release but the same problem exists there. I also browsed the PDFBox API
to somehow read the coordinate system, also inspected PDPage.getRotation()
which returned null or 90 and wasn't related to the "good" and "bad" PDFs.
Is there a way to get the coordinate's system "orientation", so we can at least
work around this by transforming x,y location and text rotation?

> I add custom text to misc exsiting PDF files. Now I wondered why my text
> doesn't appear for a specific PDF. It is not encrypted, has the same page
> size and adding Text with iText 2.1.7 works as expected. My code to add text
> is:
> ----------------------------------
> final PDPage page = (PDPage) allPages.get(i);
> final PDPageContentStream contentStream = new
> PDPageContentStream(doc, page, true, false);
> contentStream.beginText();
> contentStream.setFont(font, sizeOfFont);
> contentStream.moveTextPositionByAmount(xf, yf);
> contentStream.drawString(text);
> contentStream.endText();
> contentStream.close();
> ---------------------------------
> I tried to find differences between this PDF and other PDFs. What I noticed:
> the PDF where I can't see the text has a PDF-Version "1.3" and was created by
> "AFPL Ghostscript 8.54". Is there some known issue with PDFBox and such
> "older" PDF formats?
