## What it is
An Android ImageView replacement library that adds smooth pinch-to-zoom, pan, rotation, and animated expand/collapse transitions for photo browsing. It works with image loaders like Glide and ImageLoader, but not Fresco.

## Use cases
- add pinch-to-zoom to an image in my android app
- build a photo viewer with zoom and pan gestures
- animate an image expanding from a thumbnail to fullscreen
- zoomable image gallery for android
- rotate and scale images with touch gestures
- smooth image browsing control for android

## When to choose
- you need a drop-in zoomable ImageView for an Android app using Glide or other loaders
- you want animated thumbnail-to-fullscreen photo transitions
- you prefer a small library you can copy two source files from

## When to avoid
- your app loads images with Fresco, which is explicitly unsupported
- you need a maintained library with an active release cadence or a license
- you are building for platforms other than Android

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, image-processing, animation
- domain: mobile-development, android-tools, photography
- platform: jvm
- tags: image-viewer, zoom, pinch-to-zoom, imageview, photo-browsing, touch-gestures, android, mobile
