Package com.jsibbold.zoomage

Class ZoomageView

  • All Implemented Interfaces:
    android.graphics.drawable.Drawable.Callback, android.view.accessibility.AccessibilityEventSource, android.view.KeyEvent.Callback, android.view.ScaleGestureDetector.OnScaleGestureListener, androidx.core.view.TintableBackgroundView, androidx.core.widget.TintableImageSourceView
    public class ZoomageView
extends androidx.appcompat.widget.AppCompatImageView
implements android.view.ScaleGestureDetector.OnScaleGestureListener
    ZoomageView is a pinch-to-zoom extension of ImageView, providing a smooth user experience and a very natural feel when zooming and translating. It also supports automatic resetting, and allows for exterior bounds restriction to keep the image within visible window.
