PIL vs. CoreGraphics

In my previous entry, Goodbye PIL. Hello CoreGraphics I talked about how I had trouble getting PIL packaged up into an application. Today, I went back and got a pre-built PIL from the "offcial unofficial" PackageManager repository and tried it again. It worked! No muss, no fuss. Thanks, Bob!

Now I had both a PIL version and a CoreGraphics version so of course I raced them to see who was faster. Since this is a python blog, here was my quick and dirty main program for getting timing information:

if __name__ == '__main__': import HTMLPhotoGallery import sys import time f = open('/tmp/pylog', 'a') sys.stdout = sys.stderr = f then = time.clock() HTMLPhotoGallery.main(sys.argv[1:]) print time.clock() - then

After several test runs using the same inputs, my best time for the CoreGraphics version was 4.14 seconds and for PIL it was 1.94 seconds. Timing from run to run was consistent. The PIL version was always at least twice as fast as the CoreGraphics version. Hello PIL! Goodbye CoreGraphics! Smiley

Take care.

One python programmer's search for understanding and avocados. This isn't personal, only pythonic.
