Overview

PinchToZoom for HarmonyOs is a simple yet feature complete library for adding pinch-to-zoom functionality to an ImageView. It has sleek easing animations that make it stand out in quality and ease of use.

Features

• Pinch-to-zoom

Integrate

Adding pinch-to-zoom functionality to your ImageView is easy as this:

PhotoView photoView = (PhotoView) view.findComponentById(ResourceTable.Id_image);
photoView.setTouchEventListener(new ImageMatrixTouchHandler(getContext());

The ImageMatrixTouchHandler class has multiple getter/setter methods that allow for changing the behavior and animation settings.
