I'm using Google App Engine and using get_serving_url
to get a URL which I can append on to perform resizes and cropping. I'd like to be able to crop a square out of an image, but to also control what part of the image the crop is coming from, like passing in x/y values/
I've seen an unofficial list of options. I tried using the x/y/z options but they did not work and I'm not sure how to get them to. I don't see why GAE Image API wouldn't be able to handle this.
