Hi all, Has anybody been able to confirm this as a bug? The test script is attached to the tracker item: https://sourceforge.net/tracker/?func=detail&aid=2832896&group_id=80706&atid=560720
I did some digging to see if I could figure out how the image scale was being mangled. I had a hunch that it was due to some interaction between fixed-72-dpi code, rounding the number of pixels, and subsequent rescaling. However, the image scale still seems to be off even when the dpi setting is a multiple of 72.
