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...
