I don't see a big difference between test-600.eps and test-convert.eps when viewed in gv with magnification 10 and 0.1, respectively. Obviously there is some resampling in test-600.eps: your source image is 1494 by 1494 pixels large, which at 600 dpi is larger than the 5 by 5 cm figure created by the script (and the axes are even smaller). test-convert.eps has a bounding box of 0 0 1494 1494, so obviously it is a non-resampled image at 72 dpi. If the problem you are alluding to is in the resampling, perhaps varying the interpolation algorithm will produce a better result? See the docstring of imshow. To get a non-resampled image, figimage should work, but it doesn't seem to understand PIL images yet... -- Jouni K.
