## What it is
An Android library for displaying very large images with pan and zoom while using very little memory, built on Subsampling Scale Image View. It supports pluggable image loaders (Fresco, Glide, Picasso) and animated gif/webp display.

## Use cases
- display huge images in an android app without out-of-memory errors
- add pinch-to-zoom and pan to an image viewer
- show large photos or maps with thumbnails
- play gif and animated webp images in android
- choose between fresco, glide, or picasso as image loader

## When to avoid
- you only need to display small standard images
- your project is not android/java based
- you need actively developed features - releases have slowed since 2022
