Witryna19 wrz 2024 · Thanks @pjcunningham this technique works. Accepted as answer. The short answer to this solution was to abstract get_hash(), and to store the hash in the form: form.imghash = _img_hash. From my views.py I now can call form.imghash and get the hash generated in the validator. – Witryna4 mar 2013 · I have currently been trying to hash an image from my browser using javascript. However, I've been hashing a string of the dataURL or the pixel data that I've been retrieving from the canvas element in HTML. This is obviously not the same as hashing the raw data of the image which is what I would like to do.
