I tested this one with the Alpha file (page 5) and all my files. Rendering of the Alfa file is definitively much faster. I intend to remove the "interpolate" block from scaleImage because the effect is almost invisible (but I would leave a comment). I did not have any difference in the rendering tests (done at 96 dpi), I tried at 300 dpi where I did a visual test and saw only meaningless differences, but it is a bit slower (with interpolation). Is there a reason that you'd like to keep that block? (besides that the block was there before). It comes from PDFBOX-4218, where I had corrected previous code (PDFBOX-2750) that always interpolated. I retested the file PDFBOX-2750 and it always looks ok. Even when trying the "worst" interpolation I can't get a bad rendering of the file from PDFBOX-2750. I was wondering if java itself was improved, but no, when running an old version PDFBox the rendering was still bad. So there were other changes that improved the quality of the scaling. -- This is an automated message from the Apache Git Service.
