--------------------------------------
Summary: 100 times performance hit on creating images
Key: PDFBOX-3764
URL: https://issues.apache.org/jira/browse/PDFBOX-3764
Project: PDFBox
Issue Type: Improvement
Reporter: Daniel Persson
Attachments: callstack_1.png, callstack_2.png, test.pdf
We found that PDFBox creates a better image than poppler so we wanted to switch
out our environment to get these improvements but found a file that took about
10 minutes to create one image with PDFBox and only about 6 seconds with
poppler. So a 100 times performance hit if we where to change.
I've done some rudimentary profiling on the code and found that most of the
time is spent in ColorConvertOp.filter. Maybe there is a leaner way to
implement this in order to get a better result?
best regards
Daniel
