Question

I want to crop a thumbnail image in my Django application, so that I get a quadratic image that shows the center of the image. This is not very hard, I agree.

I have already written some code that does exactly this, but somehow it lacks a certain … elegance. I don’t want to play code golf, but there must be a way to express this shorter and more pythonic, I think.

x = y = 200 # intended size image = Image.open(filename) width = image.size[0] height = image.size[1] if (width > height):     crop_box = ( ((width - height)/2), 0, ((width - height)/2)+height, height )     image = image.crop(crop_box) elif (height > width):     crop_box = ( 0, ((height - width)/2), width, ((height - width)/2)+width )     image = image.crop(crop_box) image.thumbnail([x, y], Image.ANTIALIAS) 

Do you have any ideas, SO?

edit: explained x, y

I think this should do.

size = min(image.Size)  originX = image.Size[0] / 2 - size / 2 originY = image.Size[1] / 2 - size / 2  cropBox = (originX, originY, originX + size, originY + size)
