    Non-standard
    This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

    This API is available on Firefox OS for certified applications only.

    Summary

    The zoomRatios property is an Array of numbers representing all the supported zoom ratios. If the camera has no zoom capabilities, the value is null.

    Syntax

    var zooms = instanceOfCameraControl.capabilities.zoomRatios

    Value

    Return an Array of numbers, or null if the camera has no zoom capabilities.

    Example

    var options = {
      camera: navigator.mozCameras.getListOfCameras()[0]
    };
     
    function onSuccess(camera) {
      var zooms = camera.capabilities.zoomRatios;
    
      if (Array.isArray(zooms)) {
        zooms.forEach(function (value) {
          console.log(value)
        });
      }
    };
    
    navigator.mozCameras.getCamera(options, onSuccess)
