1. Why This Is Useful

Joget signature fields store stroke data (JSON), but many use cases need a real image output.

This script converts signature JSON into a PNG image and returns it as a Base64 data URL.

The best part is that it uses dynamic table , field , and id parameters, so you can reuse the same code anywhere without rewriting logic.

Use this when you need to:

preview a signature directly in a form or report,

embed signature image in email/PDF templates,

avoid custom external conversion services.

2. Where to Use in Joget

Form Builder: BeanShell script in a formatter/element that needs image output.

Userview/Report: render returned data URL as image source.

Workflow tools: generate signature image before notifications or documents.
