Hi all,
I have always used .png format for my matplotlib applications but now i am
compelled to save many figures in .jpeg format.
Those image should be automatically saved (no GUI) but i can't find out how to
save the images.
Executing this scripts
import pylab as p
p.rcParams['backend']='gdk'
p.figure(1)
p.plot([1,2,3,4,5,6],[3,7,5,4,6,3])
p.savefig("example.jpg")
It gives me this error
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
File "/usr/lib/python2.5/site-packages/matplotlib/pyplot.py", line 345, in
savefig
return fig.savefig(*args, **kwargs)
File "/usr/lib/python2.5/site-packages/matplotlib/figure.py", line 990, in
savefig
self.canvas.print_figure(*args, **kwargs)
File "/usr/lib/python2.5/site-packages/matplotlib/backend_bases.py", line
1373, in print_figure
'%s.' % (format, ', '.join(formats)))
ValueError: Format "jpg" is not supported.
Supported formats: emf, eps, pdf, png, ps, raw, rgba, svg, svgz.
Can anyone help me ? (.jpeg extension it doesn't work too)
By the way, what is the best backend to fulfill the task ? (better quality and
less memory leackage ?)
Thank you
···
