Quick warning about ImageMagick and EPS files (and any other vector-based graphics format)...

ImageMagick is a raster-based system.  When it loads a vector-based graphic, it implicitly rasterizes it, performs the requested operations, and then outputs the file format.  So, even if you output the result as a EPS file, you would have lost all vector-based info (like text and lines).  The result looks horrible.

I have been contemplating adding some sort of functionality like this for the various formats.  I recently ran into issues like this for an IEEE publication and had to resort to obtaining a copy of Adobe Acrobat Pro to fix up my images.  It would be nice if I could pass an option to .savefig() like 'use_cmyk=True' or something and be done with it.
