It's a bit of a pain:
xPix = 900
yPix = 600
xSize = 3 #inches
ySize = xSize/xPix*yPix
gcf().set_inches_size(xSize,ySize)
gcf().savefig('test.png',dpi=xSize/xPix)
You can also chance pyplot.rcParams - it's a dictionary of default values.

I'd also be interested if anyone has a suggestion for how to save a
figure such that the pixel dimensions of a subplot (e.g. an image) are
set.

I browsed Google, and found mainly outdated code examples (also on
scipy cookbook) then some 2008 posts on StackOverflow where at
least I find some trace that matplotlib.figure.Figure has some
instruments to change output image size, but it's in combination
from inches and dpi set. However I just couldn't find how to tell
my plt graph to use this matplotlib.figure.Figure settings, and
ended editing matplotlibrc file and changing inches and DPI there
Shouldn't be there some easier setting to set image size for
savefig() output?
