---------------------------------
Summary: PDFBox hangs indefinately when rendering certain files
Key: PDFBOX-3562
URL: https://issues.apache.org/jira/browse/PDFBOX-3562
Project: PDFBox
Issue Type: Bug
Components: Rendering
Affects Versions: 2.0.3
Environment: Ubuntu 14.04, Oracle Java SE 1.8
Reporter: Zaid Amir
There seems to be an issue with PDFBox when rendering certain PDF files, when
calling renderImageWithDPI; the call seems to hang indefinitely.
I noticed this issue on this file:[
https://1drv.ms/b/s!Av-Yk52R4YupvcUEZFueSnXFh6_pXw]
Here is the call to renderImageWithDPI:
{quote}
PDDocument doc = PDDocument.load(file);
PDFRenderer renderer = new PDFRenderer(doc);
BufferedImage img = renderer.renderImageWithDPI(0, 300.0f, ImageType.RGB);
{quote}
checking the stack trace using jstack gives me the following:
