cordova-plugin-camera

This plugin defines a global navigator.camera object, which provides an API for taking pictures and for choosing images from the system's image library.

Although the object is attached to the global scoped navigator, it is not available until after the deviceready event.

document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
    console.log(navigator.camera);
}

Installation

This requires cordova 5.0+

cordova plugin add cordova-plugin-camera

Older versions of cordova can still install via the deprecated id

cordova plugin add org.apache.cordova.camera

It is also possible to install via repo url directly ( unstable )

cordova plugin add https://github.com/apache/cordova-plugin-camera.git

camera

camera.getPicture(successCallback, errorCallback, options)

Takes a photo using the camera, or retrieves a photo from the device's image gallery. The image is passed to the success callback as a Base64-encoded String, or as the URI for the image file.

The camera.getPicture function opens the device's default camera application that allows users to snap pictures by default - this behavior occurs, when Camera.sourceType equals Camera.PictureSourceType.CAMERA. Once the user snaps the photo, the camera application closes and the application is restored.

If Camera.sourceType is Camera.PictureSourceType.PHOTOLIBRARY or Camera.PictureSourceType.SAVEDPHOTOALBUM, then a dialog displays that allows users to select an existing image. The camera.getPicture function returns a CameraPopoverHandle object, which can be used to reposition the image selection dialog, for example, when the device orientation changes.

The return value is sent to the cameraSuccess callback function, in one of the following formats, depending on the specified cameraOptions:

A String containing the Base64-encoded photo image.
A String representing the image file location on local storage (default).

You can do whatever you want with the encoded image or URI, for example:

Render the image in an <img> tag, as in the example below
Save the data locally (LocalStorage, Lawnchair, etc.)
Post the data to a remote server

NOTE: Photo resolution on newer devices is quite good. Photos selected from the device's gallery are not downscaled to a lower quality, even if a quality parameter is specified. To avoid common memory problems, set Camera.destinationType to FILE_URI rather than DATA_URL.

Kind: static method of camera

Param	Type	Description
successCallback	`onSuccess`
errorCallback	`onError`
options	`CameraOptions`	CameraOptions

Example

navigator.camera.getPicture(cameraSuccess, cameraError, cameraOptions);

camera.cleanup()

Removes intermediate image files that are kept in temporary storage after calling camera.getPicture. Applies only when the value of Camera.sourceType equals Camera.PictureSourceType.CAMERA and the Camera.destinationType equals Camera.DestinationType.FILE_URI.

Supported Platforms

iOS

Kind: static method of camera
Example

navigator.camera.cleanup(onSuccess, onFail);

function onSuccess() {
    console.log("Camera cleanup success.")
}

function onFail(message) {
    alert('Failed because: ' + message);
}

camera.onError : `function`

Callback function that provides an error message.

Kind: static typedef of camera

Param	Type	Description
message	`string`	The message is provided by the device's native code.

camera.onSuccess : `function`

Callback function that provides the image data.

Kind: static typedef of camera

Param	Type	Description
imageData	`string`	Base64 encoding of the image data, or the image file URI, depending on `cameraOptions` in effect.

Example

// Show image
//
function cameraCallback(imageData) {
   var image = document.getElementById('myImage');
   image.src = "data:image/jpeg;base64," + imageData;
}

camera.CameraOptions : `Object`

Optional parameters to customize the camera settings.

Properties

Name	Type	Default	Description
quality	`number`	`50`	Quality of the saved image, expressed as a range of 0-100, where 100 is typically full resolution with no loss from file compression. (Note that information about the camera's resolution is unavailable.)
destinationType	`DestinationType`	`FILE_URI`	Choose the format of the return value.
sourceType	`PictureSourceType`	`CAMERA`	Set the source of the picture.
allowEdit	`Boolean`	`true`	Allow simple editing of image before selection.
encodingType	`EncodingType`	`JPEG`	Choose the returned image file's encoding.
targetWidth	`number`		Width in pixels to scale image. Must be used with `targetHeight`. Aspect ratio remains constant.
targetHeight	`number`		Height in pixels to scale image. Must be used with `targetWidth`. Aspect ratio remains constant.
mediaType	`MediaType`	`PICTURE`	Set the type of media to select from. Only works when `PictureSourceType` is `PHOTOLIBRARY` or `SAVEDPHOTOALBUM`.
correctOrientation	`Boolean`		Rotate the image to correct for the orientation of the device during capture.
saveToPhotoAlbum	`Boolean`		Save the image to the photo album on the device after capture.
popoverOptions	`CameraPopoverOptions`		iOS-only options that specify popover location in iPad.
cameraDirection	`Direction`	`BACK`	Choose the camera to use (front- or back-facing).
