> My PDF document is not printed correctly. Rendering it works.
> -------------------------------------------------------------
>
> Key: PDFBOX-4821
> URL: https://issues.apache.org/jira/browse/PDFBOX-4821
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.2, 2.0.15, 2.0.19, 2.0.20
> Environment: Windows 10, JDK 1.8.0_152, 14.0.1
> Reporter: Daniel Migowski
> Priority: Major
> Labels: print, printing
> Attachments: ArtefactWhilePrinting.png,
> DevconLetterPaperPrinter.java, DevconLetterPaperRenderer.java,
> LogoOnly_Letterpaper.pdf, PDFBOX-4821_reduced7.pdf, RenderingResult.png,
> image-2020-05-01-13-43-54-357.png
>
>
> I am printing PDF files with Apache PDFBox. The attached file shows a second
> turquise square on the top of the page (See attached file
> "ArtefactWhilePrinting.png").
> When I try to render the PDF with PDFBox the result looks nice (see attached
> file "RenderingResult.png")
> I have provided the code to render / print the letterpaper, and also the
> Input PDF ("LogoOnly_Letterpaper.pdf").
> The PDF is the output of an SVN file, exported by Inkscape, but AFAIK there
> isn't even an object at the location where the square appears in printing, so
> I cannot tell what bugs lets it appear there.
> Thanks for improving the PDF component to also handle this PDF in advance,
> you guys are great.
> -Update: I tried to give a DPI number to printing, so the pixelating is done
> within PDF Box, but there the artefact still appears. So rendering with DPI
> to Image works (also with 300 DPI images), but rendering even with DPI to
> paper leads to the strange artefact.- Not true, rendering in PDFBox doesn't
> show behaviour.
> Update 2: Checked with currently nightly, bug still appears.
