## What it is
An Android library providing a custom SignaturePad View for capturing smooth, handwritten signatures. It uses variable-width Bézier curve interpolation and supports exporting signatures as Bitmaps or SVGs.

## Use cases
- capture user signatures in an android app
- add a signature pad to a checkout or contract form
- export a drawn signature as a bitmap image
- export a signature as an svg vector
- let users sign delivery confirmations on a tablet
- customize pen color and stroke width for signing

## When to choose
- you need smooth, natural-looking signature capture on Android
- you want vector (SVG) or bitmap export of signatures
- you want a drop-in custom View with configurable pen attributes

## When to avoid
- you need signature capture on iOS, web, or desktop
- you need typed or biometric signature verification
- your project is not Android/Java or Kotlin based

## Facets
- artifact type: library
