------------------------------------
Labels: print printing (was: )
> "Weasyprint" PDF's causing large memory spike
> ---------------------------------------------
>
> Key: PDFBOX-4448
> URL: https://issues.apache.org/jira/browse/PDFBOX-4448
> Project: PDFBox
> Issue Type: Bug
> Components: Rendering
> Affects Versions: 2.0.13
> Environment: Windows 10 (x64)
> Reporter: Brett
> Priority: Major
> Labels: print, printing
> Attachments: test.pdf
>
>
> PDF's created with "[weasyprint|https://weasyprint.org/samples/]"; appear to
> cause a massive spike in memory usage when printing. This can be seen in
> their "invoice sample" provided on their page (causes a ~2.5gb average spike
> for a 47kb file) or the attached test pdf (causes a ~1.8gb average spike for
> a 6kb file).
> Trying to source the cause in the java print libraries seems to indicate it's
> a problem with "nonsolid colors" being used in the drawing of the page (which
> we are passing off to a PDFPrintable). On my windows machine, normally a
> ({{sun}}) {{WPrinterJob}} gets created for printing, but for some reason
> these pdf's end up using a Paint flagged as incompatible which [fails the job
> creation|https://github.com/frohoff/jdk8u-dev-jdk/blob/master/src/windows/classes/sun/awt/windows/WPrinterJob.java#L793].
> Trying to print with just pdfbox from the command line gives similar results
> in memory usage spiking to what we are seeing in our application: {{java -jar
> pdfbox-app-2.0.13.jar PrintPDF -printerName PDFCreator test.pdf}}
