python: convert base64 encoded png image to jpg

Question

I want to convert some base64 encoded png images to jpg using python. I know how to decode from base64 back to raw:

import base64 
pngraw = base64.decodestring(p         


        

Answer 1

Right from the PIL tutorial:

To save a file, use the save method of the Image class. When saving files, the name becomes important. Unless you specify the format, the library uses the filename extension to discover which file storage format to use.

Convert files to JPEG

import os, sys
import Image

for infile in sys.argv[1:]:
    f, e = os.path.splitext(infile)
    outfile = f + ".jpg"
    if infile != outfile:
        try:
            Image.open(infile).save(outfile)
        except IOError:
            print "cannot convert", infile

So all you have to do is set the file extension to .jpeg or .jpg and it will convert the image automatically.
