Dear all,
I searched the internet but still get confused by how can I save a figure
with high dpi value to jpeg format.
I am using matplotlib 1.2.0 with ubuntu system.
In [14]: mat.__version__
Out[14]: '1.2.0'
I tried both setting the flag "savefig.dpi" flag in matplotlibrc as 300,
and use fig.savefig('temp.jpg',dpi=300) when saving the figure.
But when I checked the figure dpi with GIMP, it says 72.
Under Windows system, it also says the dpi is 72.
In the example above, the "figure.dpi" value is 80.
In [21]: mat.rcParams['figure.dpi']
Out[21]: 80
I tried to set the "figure.dpi" as 300, But then when I check the figure
with interactive window
(I use GTKAgg backend), the figure is too big (getting out of the screen)
to veiw. [But I think this
is fine as the figure size will be depend on dpi, No?]
My workflow is like I always make plot in the interactive mode,
then I adjust the figure size (by draging) or the vertical space and other
things.
Then I click the save button on the interative window or use
"fig = gcf(); fig.savefig" command to save when I feel comfortable with the
figure.
I never published yet and now is working on my first one. So I don't know
if this procedure is good or not.
but anyway, how can I save jpg figures with dpi >300 with the normal size I
see on the screen?
thanks for the help,
Chao
