Signature_pad: signature as BLOB for SQL DB?

Sure is. We use it to handle rental agreements, and after a user draws their signature in the pad and clicks save, we insert a hidden field that submits to the server and contains the signaturePad.toData(). On the server side you can do a lot of things with this, like redraw the signature at a later date, draw the signature to a composited PDF and upload to an AWS bucket to reference later.

Many thanks, could I possibly pick your brains some more about this?

Sure thing. If you want to put your email in your display profile, I will email you this afternoon

I would love some help with this to.

@apikman - another solution is described in #334

tl;dr -> depending on your browser-support needs you can just get the blob from the canvas

//select your canvas-html element
canvas.toBlob((theBlob) => {
  // do whatever with "theBlob"
});  

SORRY....i know this is closed, but i would LOOOOOOOOOOOOOVE some help on this too.
We are using an ERP solution with this Signature Tool for customers to confirm acceptance of services. On screen it looks great but the minute we print it looks TINY...the company who sold us the ERP solution has declined investing time in finding a solution..... :(
