## What it is
ImageViewTouch is an Android ImageView widget replacement with built-in zoom and pan gesture support, based on the AOSP Gallery app's implementation. It exposes APIs for setting bitmaps with a specific zoom/pan matrix and configurable display types like fit-to-screen or fit-width.

## Use cases
- pinch-to-zoom image viewer in an android app
- pan and zoom around a large bitmap
- photo gallery view with zoomable images
- restore zoom state when switching images
- fit image to screen width or height by default

## When to choose
- you need a drop-in ImageView with zoom/pan on Android
- you want to preserve or transfer zoom/pan matrix state between views
- you need configurable initial display types like fit-width or fit-height

## When to avoid
- you need an actively maintained library with recent updates
- you need advanced features like subsampling for very large images
- your project is not Android/Java based

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, image-processing
- domain: mobile-development, android-tools
- platform: jvm
- tags: imageview, zoom, pan, gesture, android-widget, android
