Batch convert images to another format

Captured at: 2013-10-26 07:39:38 UTC

Ran into a situation where I required to convert all the images used in my paper to .eps format. I was dreading having to do this manually using Gimp, when I realized that I could easily script Imagemagick to do this for me. I came up with the following piece of code that does the conversion for me. It is very quick and dirty, but it works – all figures in formats jpg, jp2, png, pdf in the directory in which the script is run get converted to Eps. Of course, you might be interested in some other format – feel free to take the code and modify accordingly.

import os, re, sys 

dirList = os.listdir( '.' )
try:
    os.mkdir( 'EpsFigs' )
except:
    pass

for f in dirList:
    m = re.match('([\w\-]+).(|jpg|jp2|png|pdf|)$',f)
    if m:
        cmd = 'convert %s EpsFigs/%s.eps'%( f, m.group(1) )
        os.system( cmd )

This requires ImageMagick and Python to work.
