MH commented on PDFBOX-854:
---------------------------
I tried to trick PDFBox: I called my method 2 times in hope that the first call
will embed the font and the second call would be sure that the used font is
embedded in the PDF. Here's the result:
1. it didn't help, i.e. the text is still not display. => it seems that the
problem is not, that the used font for the additional text is not already
embedded in the destination PDF.
2. after the first call, the font is embedded in the destination PDF. The
second call loads this PDF and will embed the font A SECOND TIME in the result
PDF! So the result PDF after the second call shows 2 times the same font as
embedded (viewed with Acrobat Reader). Then I checked all my PDFs (concatenated
and postprocessed with PDFBox) and noticed that after each postprocessing
status, the fonts get duplicated again and again! => another bug?

> 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?
