What this demonstrates
Inspect biometric signature data
A custom signature field can return the captured stroke points, timestamps, and SVG image. The demo replays those points on a canvas to show how the raw evidence can be retained independently of the rendered signature.
API used
TXDocumentViewer.signatures.setSubmitCallback
How it works
The Razor helper prepares the browser viewer and its document. Demo-specific JavaScript uses the public TXDocumentViewer API and remains encapsulated with this demo.
Source files
See the implementation
The view, browser behavior, assets, and controller are encapsulated in Demos/DocumentViewer/ESign/RawSignatureData.
