Pillow cropper resizing instead of cropping
I am using a JQuery image cropper which uses Pillow on the back-end to crop and resize the images. I have this code working in a test project but I cannot get it to work correctly in my main project. Currently, when I crop the image it should grab the region and crop it 200x200 but what it seems to be doing is resizing the image to random aspect ratios, making it very blurry, and surrounded by black. It looks to be 200x200 but the image is very small inside the 200x200 black region.
