Hi there, does anybody know if there is a way to validate what letter you’ve drawn in the canvas? I’m a bit stuck because I’m creating a game that relies on that feature.  
Thanks in advance!

@jens12341234  
You could save the canvas as an image and send it to an ocr scanner api

Return the text and check against the assumed value

I have taken a look at your project and it helped me a lot, now I just need to upload the canvas picture to retrieve the number.
