Hand Signature¶
HandSignature captures a handwritten signature in a 300 × 180 canvas and uploads it as a PNG through the file upload service. The bound node stores the file identifier and receives file metadata, including the uploaded URL. If the existing value is a revisioned file, a new revision can be linked instead of replacing the identifier.
Availability and Required Validation¶
The signing dialog is available only when the widget is editable and the current user has file-upload permission. The dialog provides Clear and Undo commands and refuses an empty signature. Use a separate validation rule if a signature is mandatory.
This widget records a graphical signature, not by itself a legal-signature workflow. Apply the required identity, audit, consent, certificate, and retention controls in the surrounding process where legal or evidentiary signing is required.
