Re: [matplotlib-devel] matplotlib.pyplot.imsave bug

[Michael D. <md...@st...>]

What version of matplotlib are you using?  This appears to be fixed in 
the latest 1.1.  If you can let me know what version you're using, 
perhaps it will be easy to provide a patch if you're not able to upgrade 
wholesale.
