What this demonstrates
Signature Fields
Signature fields provide a visible signing location that can receive an image, become an interactive PDF signature field, or be associated with an X.509 certificate during server-side PDF export.
API used
TXTextControl.signatureFields
How it works
The browser inserts a centered field anchored to the current text position and enables actions only while a signature field is selected. Client-side export preserves empty fields for later signing. Server-side export loads the document into ServerTextControl and associates every named field with an exportable certificate through SaveSettings.SignatureFields.
