Python Image (PIL) library not resizing properly per kwargs

Question

Here is my code:

import Image
import sys
import json

if __name__ == '__main__':
    args = json.loads(sys.argv[1])
    srcPath = args.get('srcPath')
    image = Image.open(srcPath)
    sizes = {}

    for variant_name, dimensions in args.get('sizes').items():
        if '%' in dimensions:
            sizes[variant_name] = image.size
        else:
            width = int(dimensions.split('x')[0])
            height = int(dimensions.split('x')[1])
            widthAndHeight = (width, height)
            sizes[variant_name] = widthAndHeight

    for key, val in sizes.items():
        imageName = key + '.' + srcPath.split('.')[1]
        convertedImage = image.resize(val, Image.ANTIALIAS)
        image.save(imageName)
        print 'done'

And I'm calling it with:

python image.py '{"sizes":{"large":"200x150","orig":"100%x100%"},"srcPath":"/Users/bobcobb/Desktop/avocado.png"}'

If the argument 100%x100% is passed in, then I want to resize to the original size, otherwise, I want to resize to the passed in size. So the above code would generate 2 images (one original, the other 200x150).

Right now, it just saves the image as the original size for both. How can I fix this?

Answer 1

Your problem is that the resized image is assigned to convertedImage , but you save the original image (at the new filename).

So changing this line

image.save(imageName)

into

convertedImage.save(imageName)

solves this problem.
