**HandSigned** is a react component that allows you to easily expose a manual signature interface in your web application.

This library uses the classic canvas element to render the signature.

You can even use `ref` property to execute internal methods of the component like `clear`, `getDataURL`, `getRawData`. You can also read the original canvas element reference if you need.
