[yt-users] saving files with a different resolution

[Luigi Iapichino]

Hi Matt,

both methods work, but I have a further problem: if I try to add density 
contours, they appear in the plot, but they are not superimposed at the 
correct location. They look like shifted, and I suppose that 

p.modify["contour"]("Density", ncont=5,take_log=True)

does not "see" that I changed the size of the figure.
Am I missing something?
Thanks,

  Luigi
