Hi all,
I want to save a figure just like it is displayed i.e. the same dpi (wxAgg). However, the default Figure.savefig uses a different dpi setting than the figure as displayed, so I'm doing:
dpi = Fig.get_dpi()
Fig.savefig(str(path), dpi=dpi)
which seems to work, but seems more awkward than it should be. Is there a flag or something I'm missing?

I think this line in the rc file is the trick
#savefig.dpi : 100

nope. I think all that does is set the default dpi for savefig. I don't want any default, I want it to use the same dpi that is being used for display, and I don't know ahead of time what that is, I expect it is system dependent.
Or do you mean that if I comment out that line, it will default to the one already in use? In which case, I need to go figure out how to change that in code, rather than messing with my matplotlibrc.

I guess you could read the rcParams value that corresponds to the
screen display and set rcParams['savefig.dpi'] to that value (this
might work):
mydpi = rcParams['figure.dpi']
rcParams['savefig.dpi'] = mydpi
But that seems slightly hackish and maybe not much more elegant than
what you are currently doing with passing dpi into savefig.
FWIW,
Ryan
