> 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
