Viktor Merkel created PDFBOX-5570:
-------------------------------------
Summary: Long Render Time and Freezing when Printing Document
Key: PDFBOX-5570
URL: https://issues.apache.org/jira/browse/PDFBOX-5570
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 2.0.24
Environment: Windows 10
Amazon Corretto Windows x64 JDK 11
Reporter: Viktor Merkel
Attachments: non-printable.pdf
Opening the attached PDF document in the PDFBox PDF Debugger can take up to 3
seconds on average to render the page. However, attempting to print the PDF
document in the PDF Debugger using the "Microsoft Print to PDF" printer will
cause the entire application to freeze and become unresponsive to mouse inputs.
During the freeze, a thread dump was generated, and it was observed that the
AWT-EventQueue-0 seems to be stuck at a fillPath procedure. The full stacktrace
is provided below:

Acrobat Reader renders the document much faster and printing with the same
printer is done quickly.
It was discovered that commenting out the following lines in the function
fillPath(int windingRule) in org.apache.pdfbox.rendering.PageDrawer makes
printing possible again. However, this leads to the disadvantage that some
elements will not be drawn (of course):
{code:java}
Shape shape;
if (!(graphics.getPaint() instanceof Color))
{
// apply clip to path to avoid oversized device bounds in shading
contexts (PDFBOX-2901)
Area area = new Area(linePath);
area.intersect(new Area(graphics.getClip()));
intersectShadingBBox(getGraphicsState().getNonStrokingColor(),
area);
shape = area;
}
else
{
shape = linePath;
}
// when commenting this out, print works again
// if (isContentRendered())
// {
// graphics.fill(shape);
// } {code}
Does anyone know of a permanent solution to this problem?
