CookBook - Validate an image size

django version : 0.91

To check the height and width of an image uploaded via your form, you can implement this method into your view.py or custom manipulator.

You need PIL http://www.pythonware.com/products/pil/ to be installed.

Code

Here we check that the image is 100*100 pixels.

import Image
import StringIO

def isValidSize(field_data, all_data):
    im = Image.open(StringIO.StringIO(field_data["content"]))
    if im.size != (100,100):
        raise validators.ValidationError, "The image size does not match 100*100"
