## What it is
An Android PhotoView library that lets users zoom images and drag them down to dismiss the activity, mimicking WeChat's photo viewer behavior. It is built on top of the popular PhotoView library and adds drag-to-exit gestures with an exit listener.

## Use cases
- add pinch-to-zoom and drag-to-dismiss to an Android image viewer
- recreate WeChat-style photo preview with swipe down to close
- show full-screen images that can be dragged to finish the activity
- zoomable image view inside a ViewPager
- detect taps and matrix changes on a zoomable photo

## When to avoid
- you need an actively maintained library with recent updates
- you target Jetpack Compose rather than View-based UIs
- you need a license-clean dependency for compliance-sensitive projects
