Möglichkeit die Unterschrift als JPEG zu speichern

[FloMeh]

Hello,

is there a way to extend the plugin so that you can save the signature as JPEG?
According to the documentation of signature_pad this should be possible, but I don't know where I can adapt this to make it work with the plugin.

// Returns signature image as data URL (see https://mdn.io/todataurl for the list of possible parameters)
signaturePad.toDataURL(); // save image as PNG
signaturePad.toDataURL("image/jpeg"); // save image as JPEG
signaturePad.toDataURL("image/svg+xml"); // save image as SVG

Many thanks for the help!
