Turn output from Signature Pad into images

Project description

Signature Pad is a nice tool that allows users to provide a drawn signature. Because of the flakiness of some browsers, it’s probably recommend to generate an actual image of the signature on the server. And that’s what signapadpy does with a little help of Pillow (or PIL).

First install it:

pip install signapadpy

Next, import what you need (padding is optional):

from signapadpy import create_image, Padding

Then load the lines of the signature you want to convert into an image:

lines = load_signature_pad_output(from_something)

And create the image:

image = create_image(lines)

The image is an instance of PIL’s (or Pillow’s) Image, so you can choose to display it:

image.show()

Or save it:

image.save('signature.png')

If you’d like to render the image with Django, you could do it like this:

from django.http import HttpResponse
from django.shortcuts import get_object_or_404

from signapadpy import create_image


def view_signature(request, pk):
    # Django view, assuming a Sigature model with a lines attribute
    signature = get_object_or_404(Signature, pk=pk)
    return signature_to_response(signature.lines)

def signature_to_response(lines):
    image = create_image(lines)
    response = HttpResponse(mimetype='image/png')
    image.save(response, 'PNG')
    return response
