[yt-users] saving files with a different resolution

[Matthew Turk]

Hi Luigi,

Yup, you'll just need to provide it with a new "figure".  In
matplotlib, figures are the background - the entire image, if you will
- and "axes" are individual plot elements on that.  Here we're going
to create a figure with 100 dpi that's 12 inches by 9 inches -- this
should be 1200 by 900 pixels:

fig = raven.matplotlib.figure.Figure(dpi = 100, figsize = (12, 9))
p = pc.add_projection("Temperature", 0, weight_field="Density")

That's the slightly harder way -- you'll have to generate a new Figure
object for every plot.  There's a shortcut in yt already, though, that
accepts a figsize=(width, height) argument, where width and height are
in inches:

p = pc.add_projection("Temperature", 0, weight_field="Density",
fig_size=(20, 16))

if you wanted 2000 by 1600 pixels.

Does that help out?

Best,

Matt
