PS and imshow

This may not be what it seems. The native coordinate system for
PostScript is in points, which are 1/72 if an inch, so it's common to

Yes, this is exactly right and the reason we do it this way. We
support fractional points so indeed you have higher resolutions. Off
the top of my head, I am not sure what is going on with the image
resolution problem....

I just tried with current svn, and the following script produces two
results that have visibly different resolutions:

#!/usr/bin/python
from pylab import *
foo = rand(10,10)
imshow(foo)
savefig('foo10.ps', dpi=10)
savefig('foo100.ps', dpi=100)

Perhaps the original poster could show a bit of code where the scaling
fails?

(I'm not sure if figimage is doing the right thing, though...)
