Anything Else

Just dumping a script I just wrote for a friend.

import Image, sys # required PIL: http://www.pythonware.com/products/pil/
from optparse import OptionParser

parser = OptionParser()
parser.add_option("--input", help="Input image path.")
parser.add_option("--output", help="Output file name for the image.")
parser.add_option(
    "--width", default=45, type="int",
    help="Maximum width, in pixels."
)
parser.add_option(
    "--height", default=45, type="int",
    help="Maximum height, in pixels."
)

def main():
    (options, args) = parser.parse_args()
    img = Image.open(options.input)
    img.thumbnail(
        (options.width, options.height), Image.ANTIALIAS
    )
    img.convert("RGB").save(options.output)

if __name__ == "__main__":
    status = main()
    sys.exit(status) 

Python makes it easy. Maintains aspect ratio.
