Add Signature to the Canvas
Build a custom drawing UI and insert signature as image or SVG
Polotno ships a built-in drawing tool (the Draw side-panel section, or store.setTool('draw')) for freehand strokes on the canvas; each stroke is added to the page as an svg element. When you need your own drawing UI instead — a signature pad, for instance — capture the drawing yourself and add the result to the canvas using image or svg elements.
In this demo, we create a custom side panel to add a signature to the document.
