Hi, Mike Fitzgerald reported bug #2832896 and has been investigating its causes:
https://sourceforge.net/tracker/?func=detail&aid=2832896&group_id=80706&atid=560720 The problem is that images are not drawn at exactly the same coordinates as other artists, so markers drawn on top of images are slightly off in pdf and eps output. Apparently this can be fixed, at least to some degree, by removing the round(...) operations from renderer.draw_image(gc, round(l), round(b), im) in _AxesImageBase.draw and making a slightly more involved change in AxesImage.make_image (the details are in the bug report). I haven't had time to investigate what this does to other backends, but I imagine the rounding would be necessary for raster backends. Can someone who is more familiar with the image machinery comment on the matter? Do we need some kind of vector/raster indication in the backends, in addition to the get_image_magnification method? -- Jouni K.
