This API is available on Firefox OS for privileged or certified applications only.
Summary
The zoom
property value is a number that defines the zoom factor that is to be used when taking photographs. When set, its new value must be chosen from the list of options specified by CameraCapabilities.zoomRatios
.
If the new value is not one of those possible values, the new value is rounded to the nearest supported value.
Syntax
var zoomFactor = instanceOfCameraControl.zoom
Value
Returns a number representing the current scene mode. The default value is 1.
Example
var options = { camera: navigator.mozCameras.getListOfCameras()[0] }; function onSuccess( camera ) { var zoomRatios = camera.capabilities.zoomRatios; if (zoomRatios !== null && zoomRatios.indexOf(2) > -1) { camera.zoom = 2; } }; navigator.mozCameras.getCamera(options, onSuccess)
Specification
Not part of any specification; however, this API should be removed when the WebRTC Capture and Stream API has been implemented.
