[jira] Commented: (PDFBOX-854) PDPageContentStream.drawString()
doesn't work with all PDFs
[ https://issues.apache.org/jira/browse/PDFBOX-854?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12970777#action_12970777 ]
MH commented on PDFBOX-854:
---------------------------
Can't get it to work: I downloaded the latest snapshots (pdfbox-1.4.0-20101211.181302-26.jar, fontbox-1.4.0-20101211.181302-27.jar, jempbox-1.4.0-20101211.181302-27.jar), ensured to recompile everything (log shows new PDFBox version number) text now "jumps" all over the place. I have no idea what that means:
92 if (rotate)
93 {
94 // rotate the text according to the page rotation
95 contentStream.setTextRotation(Math.PI/2, centeredXPosition, centeredYPosition);
96 }
97 else
98 {
99 contentStream.setTextTranslation(centeredXPosition, centeredYPosition);
100 }
Why is ther an if/else? What does setTextTranslation do? And what is the additional parameter in the PDPageContentStream constructor?

> 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?
