FAQPage Schema

How do I capture an electronic signature on an HTML canvas for a web form?▼

Capture electronic signatures on an HTML canvas by instantiating the signature pad on a target element, which manages stroke events and exports the data URL for web form integration.

Can I export canvas signature data as an image or data URL for document storage?▼

Yes, you can export canvas signature data as a data URL or SVG format using fromData and fromDataURL methods, enabling seamless document storage and image export workflows.

Does high-DPI canvas support affect the quality of web signatures?▼

High-DPI canvas support ensures electronic signatures render crisply on retina displays by scaling the canvas drawing surface, preventing blurry strokes during web signature capture.

How do I integrate electronic signature capture into offline-capable web apps?▼

Integrate electronic signature capture into offline-capable web apps by binding stroke management and event handling logic to your front-end framework without requiring external dependencies.

What is the best way to manage strokes when capturing signatures on enrollment forms?▼

The best way to manage signature strokes on enrollment forms is using built-in stroke management functions that reconstruct and export drawing data directly from the HTML canvas.

Why does my signature pad export a blank data URL before signing?▼

A signature pad exports a blank data URL if the canvas stroke management has captured no input, requiring user interaction on the HTML element before generating the export image.
