Supported Cordova Platforms

Methods

The plugin is exposed on the window object as Scaler. Although it is in the global scope, it is not available until after the deviceready event. There are two API calls available:

Scaler.viewportZoom

Zooms the scroll view to the size of the viewport (essentially, this is the same as <meta name="viewport" content="initial-scale=1">).

Scaler.viewportZoom({ animate: true })

Scaler.zoom

Allows zooming the scroll view to any arbitrary rectangular area.

Scaler.zoom({ x: 50, y: 50, width: 300, height: 700, animate: false })

iOS will not follow the width and height strictly if they do not match the viewport aspect ratio.
