Re: [Matplotlib-users] PS Output from WXAGG / wxPython application

[Eli G. <eg...@se...>]

Darren,

It was my impression that savefig() only supports jpeg and png format.  From 
the docs:
http://matplotlib.sourceforge.net/matplotlib.pylab.html#-savefig

savefig(*args, **kwargs)
SAVEFIG(fname, dpi=150, facecolor='w', edgecolor='w',
    orientation='portrait'):

    Save the current figure to filename fname.  dpi is the resolution
    in dots per inch.

    Output file types currently supported are jpeg and png and will be
    deduced by the extension to fname


Also I guess I'm not clear if saving to PS/EPS format actually creates a 
line drawing/ vector image or
just creates a bitmap and encapsulates the bitmap in the PS/EPS format.  I'm 
looking to
be able to save as a line drawing or vector-type format.

Thanks,

Eli
