## What it is
A TypeScript canvas library for capturing handwritten signatures in the browser with a natural pen-brush (variable stroke width) effect. It works with any frontend framework on both desktop and mobile, and supports exporting PNG/JPG, undo/redo, and canvas rotation.

## Use cases
- capture handwritten signatures in a web form
- add e-signature pad to H5 mobile page
- draw signatures with realistic pen pressure effect on canvas
- integrate signature capture into Vue or React app
- export signed signature as PNG or JPG image
- replace signature_pad with smoother stroke rendering

## When to choose
- you need a browser-based signature pad with a natural brush/pen-tip effect
- you want a framework-agnostic library usable in Vue, React, or plain JS
- you need undo/redo, clear, and image export out of the box
- you target both desktop and mobile touch devices

## When to avoid
- you need a native app or WeChat mini-program signature pad (use mini-smooth-signature instead)
- you require actual stylus pressure sensitivity rather than speed-based stroke width
- you need server-side or offline document signing workflows

## Facets
- artifact type: library
- maturity: active
- function: ui-components, image-processing
- domain: web-development, frontend
- platform: browser, cross-platform
- tags: canvas, signature, handwriting, e-signature, typescript, pen-brush-effect
