Works fine with the current trunk (926714) on winXP with JDK1.6.18
@Peter: Can you rerun the test with the current trunk version?

------------------------------------
Well, I retried with the current trunk version on Linux (JDK 1.6). Unfortunately the Problem still occurs.
Quite fishy that it worked just well with PDFBox 0.7.3.

[jira] Commented: (PDFBOX-667) Last characters in a line overlap
when a PDF is printed

Maruan Sahyoun commented on PDFBOX-667:
---------------------------------------
The reason the last character is still misplaced is related to the fact that the character is drawn independently from the rest of the line already within the pdf i.e. it's a different object. The patch handled the fact that for the other lines the last character was output by PDFBox as a separate Object although it belonged to the same string in the PDF.
The PDF is defining Helvetica for rendering the text. To which printer/driver are you printing?

Peter Deter updated PDFBOX-667:
-------------------------------
Attachment: out_patch.ps
By and large the patch fixes the problem. Enough to sate me.
However there still appears to be a problem with the last character on the document (see attached out_patch.ps) which is still misplaced slightly.

The document prints fine on Max and Linux using the latest trunk (see raw.out.pdf). On Windows a warning occurs and one line is missing from the output (see raw.out.win.pdf). In all cases there is no overlapping of chars.

Andreas Lehmkühler commented on PDFBOX-667:
-------------------------------------------
Due to some sideeffects within textextraction (see PDFBOX-718) I've reverted the patch with version 941807.
We have to dig deeper into the textextraction part to see what's causing the sideeffect.

Maruan Sahyoun updated PDFBOX-667:
----------------------------------
Attachment: PDFStreamEngine.patch
The misplacement of the last char in the line occured because the last char was printed individually although the COSString contained the complete line. The patch resolves that issue. Please review and apply if you see fit.

[jira] Updated: (PDFBOX-667) Last characters in a line overlap when
a PDF is printed
Posted by "Villu Ruusmann (JIRA)" <ji...@apache.org>.

Villu Ruusmann updated PDFBOX-667:
----------------------------------
Attachment: raw_pagedraw.png
Maruan has correctly spotted that the current loop termination condition is wrong, but it is not the root cause of the problem.
The sample file raw.pdf uses external TrueType font "Helvetica". Unlike Acrobat Reader and other "native" PDF viewer programs, PDFBox does not have a built-in support for this font and uses "Arial-MT" instead. All in all this results in incorrect font metrics.
The good news is that PDFBOX-663 provides remedy here - the text is still drawn using "Arial" instead of "Helvetica", but the font metrics is correct. Please see the sample image "raw_pagedraw.png".
Peter, please check out the SVN trunk one more time (PDFBOX-663 was committed yesterday) and see if it solves your problem.
