A Kotlin Android library providing 2D zoom and pan components for View hierarchies, images, and video streams, built around a flexible Matrix-based ZoomEngine. It includes ZoomLayout, ZoomImageView, and ZoomSurfaceView with OpenGL rendering support.

Use cases

• add pinch-to-zoom to an Android ImageView
• make a View hierarchy pannable and zoomable with touch gestures
• zoom and pan a video stream or camera preview surface
• programmatically animate zoom and pan on Android
• build an interactive map or floorplan viewer on Android
• support clickable views inside a zoomable container

When to choose

• you need lightweight, dependency-free zoom/pan on Android down to API 16
• you want both touch-driven and programmatic zoom control with animation
• you need to zoom arbitrary View hierarchies, not just images
• you want OpenGL-accelerated zooming of SurfaceView content like video

When to avoid

• you target platforms other than Android
• you need 3D zoom or complex gesture recognition beyond pan/zoom
• you need a library under active development with frequent updates
• you want Jetpack Compose-native zoom components
