80/**
81 * @description Takes a photo using the camera, or retrieves a photo from the device's
82 * image gallery.  The image is passed to the success callback as a
83 * Base64-encoded `String`, or as the URI for the image file.
84 *
85 * The `camera.getPicture` function opens the device's default camera
86 * application that allows users to snap pictures by default - this behavior occurs,
87 * when `Camera.sourceType` equals [`Camera.PictureSourceType.CAMERA`]{@link module:Camera.PictureSourceType}.
88 * Once the user snaps the photo, the camera application closes and the application is restored.
89 *
90 * If `Camera.sourceType` is `Camera.PictureSourceType.PHOTOLIBRARY` or
91 * `Camera.PictureSourceType.SAVEDPHOTOALBUM`, then a dialog displays
92 * that allows users to select an existing image.
93 *
94 * The return value is sent to the [`cameraSuccess`]{@link module:camera.onSuccess} callback function, in
95 * one of the following formats, depending on the specified

96 * `cameraOptions`:
97 *
98 * - A `String` containing the Base64-encoded photo image.
99 * - A `String` representing the image file location on local storage (default).
100 *
101 * You can do whatever you want with the encoded image or URI, for
102 * example:
103 *
104 * - Render the image in an `<img>` tag, as in the example below
105 * - Save the data locally (`LocalStorage`, [Lawnchair](http://brianleroux.github.com/lawnchair/), etc.)
106 * - Post the data to a remote server
107 *
108 * __NOTE__: Photo resolution on newer devices is quite good. Photos
109 * selected from the device's gallery are not downscaled to a lower
110 * quality, even if a `quality` parameter is specified.  To avoid common
111 * memory problems, set `Camera.destinationType` to `FILE_URI` rather
112 * than `DATA_URL`.
