-----------------------------
Summary: "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
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}}
