« DOM Reference

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 maxMeteringAreas property is a number that defines the maximum number of metering areas supported by the camera.

Syntax

var max = instanceOfCameraControl.capabilities.maxMeteringAreas

Value

Return a number.

Example

var options = {
  camera: navigator.mozCameras.getListOfCameras()[0]
};
 
function onSuccess(camera) {
  console.log(camera.capabilities.maxMeteringAreas);
};

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.
