An Android library providing a highly configurable, extendable image view for displaying very large images with deep zoom support. It uses subsampling and tiling to load only visible high-resolution regions, avoiding OutOfMemoryError while supporting pinch-to-zoom, panning, rotation, and animations.
Use cases
- display huge images in an Android photo gallery without running out of memory
- show zoomable maps or building plans in an Android app
- add pinch-to-zoom and panning to large images
- load high-resolution tiles of a large image as the user zooms in
- display a preview image while a large image loads
- overlay custom markers or annotations on a zoomable image
When to choose
- your Android app must display very large images (maps, plans, high-res photos) with smooth zooming
- you need to avoid OutOfMemoryError when showing high-resolution images
- you want configurable zoom gestures, rotation, and animation out of the box
- you need to extend an image view with overlays and custom touch handling
When to avoid
- you only need to display small images that fit comfortably in memory
- you are building for platforms other than Android
- you need a full photo gallery UI rather than just an image view component
- your project requires Kotlin-first or Jetpack Compose-native solutions without interop
