Signature data format

The Signature SDK generates the signature data in a proprietary Wacom format which we do not disclose, partly in order to prevent forgery.
If you want to capture the biometric data within the signature image this can be done by encoding that data in the signature image using the RenderEncodeData flag.

There are sample programs showing how to do this, e.g. CaptureImage.js in the JScript folder of the Signature SDK samples on GitHub.
