camera.getPicture
Errata
Example
Take a photo and retrieve it as a base64-encoded image:
navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.DATA_URL
});
function onSuccess(imageData) {
var image = document.getElementById('myImage');
image.src = "data:image/jpeg;base64," + imageData;
}
function onFail(message) {
alert('Failed because: ' + message);
}
Take a photo and retrieve the image's file location:
navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.FILE_URI });
function onSuccess(imageURI) {
var image = document.getElementById('myImage');
image.src = imageURI;
}
function onFail(message) {
alert('Failed because: ' + message);
}
Preferences (iOS)
-
CameraUsesGeolocation (boolean, defaults to false). For capturing JPEGs, set to true to get geolocation data in the EXIF header. This will trigger a request for geolocation permissions if set to true.
<preference name="CameraUsesGeolocation" value="false" />
Amazon Fire OS Quirks
Amazon Fire OS uses intents to launch the camera activity on the device to capture images, and on phones with low memory, the Cordova activity may be killed. In this scenario, the image may not appear when the cordova activity is restored.
Android Quirks
Android uses intents to launch the camera activity on the device to capture images, and on phones with low memory, the Cordova activity may be killed. In this scenario, the image may not appear when the Cordova activity is restored.
Browser Quirks
Can only return photos as base64-encoded image.
Firefox OS Quirks
Camera plugin is currently implemented using Web Activities.
iOS Quirks
Including a JavaScript alert()
in either of the callback functions
can cause problems. Wrap the alert within a setTimeout()
to allow
the iOS image picker or popover to fully close before the alert
displays:
setTimeout(function() {
// do your thing here!
}, 0);
Windows Phone 7 Quirks
Invoking the native camera application while the device is connected via Zune does not work, and triggers an error callback.
Tizen Quirks
Tizen only supports a destinationType
of
Camera.DestinationType.FILE_URI
and a sourceType
of
Camera.PictureSourceType.PHOTOLIBRARY
.

Android also uses the Crop Activity for allowEdit, even though crop should work and actually pass the cropped image back to Cordova, the only one that works consistently is the one bundled with the Google Plus Photos application. Other crops may not work.
-
Camera.PictureSourceType.PHOTOLIBRARY
andCamera.PictureSourceType.SAVEDPHOTOALBUM
both display the same photo album.

Windows Phone 7 and 8 Quirks
-
Ignores the
allowEdit
parameter. -
Ignores the
correctOrientation
parameter. -
Ignores the
cameraDirection
parameter. -
Ignores the
saveToPhotoAlbum
parameter. IMPORTANT: All images taken with the wp7/8 cordova camera API are always copied to the phone's camera roll. Depending on the user's settings, this could also mean the image is auto-uploaded to their OneDrive. This could potentially mean the image is available to a wider audience than your app intended. If this a blocker for your application, you will need to implement the CameraCaptureTask as documented on msdn : http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394006.aspx You may also comment or up-vote the related issue in the issue tracker -
Ignores the
mediaType
property ofcameraOptions
as the Windows Phone SDK does not provide a way to choose videos from PHOTOLIBRARY.
