## What it is
PinchImageView is a lightweight Android image gesture control that extends ImageView with pinch-to-zoom, swipe inertia, double-tap zoom, and boundary rebound behavior. It ships as a single Java class file with no external dependencies, making it trivial to integrate into any Android project.

## Use cases
- pinch to zoom images in an android app
- double-tap zoomable imageview
- view very large images in segments on android
- browse long images with gestures
- thumbnail to full-size image transition animation

## When to choose
- you need a drop-in ImageView replacement with pinch-zoom gestures
- you want zero dependencies and a single-file integration
- you need to display extremely large or long images with smooth gesture handling

## When to avoid
- you need a multi-platform (non-Android) image viewer
- you require built-in network image loading rather than using a separate loader
- your project is Kotlin-first and you prefer a Kotlin-maintained library

## Facets
- artifact type: library

- function: ui-components, image-processing
- domain: mobile-development, android-tools
