3927735d09 CB-8706, CB-8707 saveToPhotoAlbum improvements and some refactoring

accessing user libs. This way the app doesnt have to depend on extra
capabilities.

- Some refactoring to help on navigating code easier

This closes #78

Plugin documentation: [doc/index.md](doc/index.md)
[![Build Status](https://travis-ci.org/apache/cordova-plugin-camera.svg)](https://travis-ci.org/apache/cordova-plugin-camera)
This is `dev` - the deprecated development branch of this plugin; development of this plugin has moved to the `master` branch
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
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
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 method
itself returns a `CameraPopoverHandle` object that can be used to
reposition the file selection popover.
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### Description
The `camera.getPicture` function opens the device's default camera
application that allows users to snap pictures. This behavior occurs
by default, 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](http://brianleroux.github.com/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`.
### Supported Platforms
- Amazon Fire OS
- Android
- BlackBerry 10
- Browser
- Firefox OS
- iOS
- Tizen
- Windows Phone 7 and 8
- Windows 8
- Windows
### 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](https://hacks.mozilla.org/2013/01/introducing-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`.
### 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);
}
## CameraOptions
Optional parameters to customize the camera settings.
{ quality : 75,
destinationType : Camera.DestinationType.DATA_URL,
sourceType : Camera.PictureSourceType.CAMERA,
allowEdit : true,
encodingType: Camera.EncodingType.JPEG,
targetWidth: 100,
targetHeight: 100,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false };
### Options
- __quality__: Quality of the saved image, expressed as a range of 0-100, where 100 is typically full resolution with no loss from file compression. The default is 50. _(Number)_ (Note that information about the camera's resolution is unavailable.)
- __destinationType__: Choose the format of the return value. The default is FILE_URI. Defined in `navigator.camera.DestinationType` _(Number)_
Camera.DestinationType = {
DATA_URL : 0, // Return image as base64-encoded string
FILE_URI : 1, // Return image file URI
NATIVE_URI : 2 // Return image native URI (e.g., assets-library:// on iOS or content:// on Android)
};
- __sourceType__: Set the source of the picture. The default is CAMERA. Defined in `navigator.camera.PictureSourceType` _(Number)_
Camera.PictureSourceType = {
PHOTOLIBRARY : 0,
CAMERA : 1,
SAVEDPHOTOALBUM : 2
};
- __allowEdit__: Allow simple editing of image before selection. _(Boolean)_
- __encodingType__: Choose the returned image file's encoding. Default is JPEG. Defined in `navigator.camera.EncodingType` _(Number)_
Camera.EncodingType = {
JPEG : 0, // Return JPEG encoded image
PNG : 1 // Return PNG encoded image
};
- __targetWidth__: Width in pixels to scale image. Must be used with __targetHeight__. Aspect ratio remains constant. _(Number)_
- __targetHeight__: Height in pixels to scale image. Must be used with __targetWidth__. Aspect ratio remains constant. _(Number)_
- __mediaType__: Set the type of media to select from. Only works when `PictureSourceType` is `PHOTOLIBRARY` or `SAVEDPHOTOALBUM`. Defined in `nagivator.camera.MediaType` _(Number)_
Camera.MediaType = {
PICTURE: 0, // allow selection of still pictures only. DEFAULT. Will return format specified via DestinationType
VIDEO: 1, // allow selection of video only, WILL ALWAYS RETURN FILE_URI
ALLMEDIA : 2 // allow selection from all media types
};
- __correctOrientation__: Rotate the image to correct for the orientation of the device during capture. _(Boolean)_
- __saveToPhotoAlbum__: Save the image to the photo album on the device after capture. _(Boolean)_
- __popoverOptions__: iOS-only options that specify popover location in iPad. Defined in `CameraPopoverOptions`.
- __cameraDirection__: Choose the camera to use (front- or back-facing). The default is BACK. Defined in `navigator.camera.Direction` _(Number)_
Camera.Direction = {
BACK : 0, // Use the back-facing camera
FRONT : 1 // Use the front-facing camera
};
### Amazon Fire OS Quirks
- Any `cameraDirection` value results in a back-facing photo.
- Ignores the `allowEdit` parameter.
- `Camera.PictureSourceType.PHOTOLIBRARY` and `Camera.PictureSourceType.SAVEDPHOTOALBUM` both display the same photo album.
### Android Quirks
- Any `cameraDirection` value results in a back-facing photo.
- 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` and `Camera.PictureSourceType.SAVEDPHOTOALBUM` both display the same photo album.
### BlackBerry 10 Quirks
- Ignores the `quality` parameter.
- Ignores the `allowEdit` parameter.
- `Camera.MediaType` is not supported.
- Ignores the `correctOrientation` parameter.
- Ignores the `cameraDirection` parameter.
### Firefox OS Quirks
- Ignores the `quality` parameter.
- `Camera.DestinationType` is ignored and equals `1` (image file URI)
- Ignores the `allowEdit` parameter.
- Ignores the `PictureSourceType` parameter (user chooses it in a dialog window)
- Ignores the `encodingType`
- Ignores the `targetWidth` and `targetHeight`
- `Camera.MediaType` is not supported.
- Ignores the `correctOrientation` parameter.
- Ignores the `cameraDirection` parameter.
### iOS Quirks
- Set `quality` below 50 to avoid memory errors on some devices.
- When using `destinationType.FILE_URI`, photos are saved in the application's temporary directory. The contents of the application's temporary directory is deleted when the application ends.
### Tizen Quirks
- options not supported
- always returns a FILE URI
### 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](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](https://issues.apache.org/jira/browse/CB-2083)
- Ignores the `mediaType` property of `cameraOptions` as the Windows Phone SDK does not provide a way to choose videos from PHOTOLIBRARY.
## CameraError
onError callback function that provides an error message.
function(message) {
// Show a helpful message
}
### Parameters
- __message__: The message is provided by the device's native code. _(String)_
## cameraSuccess
onSuccess callback function that provides the image data.
function(imageData) {
// Do something with the image
}
### Parameters
- __imageData__: Base64 encoding of the image data, _or_ the image file URI, depending on `cameraOptions` in effect. _(String)_
### Example
// Show image
//
function cameraCallback(imageData) {
var image = document.getElementById('myImage');
image.src = "data:image/jpeg;base64," + imageData;
}
## CameraPopoverHandle
A handle to the popover dialog created by `navigator.camera.getPicture`.
### Methods
- __setPosition__: Set the position of the popover.
### Supported Platforms
- iOS
### setPosition
Set the position of the popover.
__Parameters__:
- `cameraPopoverOptions`: the `CameraPopoverOptions` that specify the new position
### Example
var cameraPopoverHandle = navigator.camera.getPicture(onSuccess, onFail,
{ destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
popoverOptions: new CameraPopoverOptions(300, 300, 100, 100, Camera.PopoverArrowDirection.ARROW_ANY)
});
// Reposition the popover if the orientation changes.
window.onorientationchange = function() {
var cameraPopoverOptions = new CameraPopoverOptions(0, 0, 100, 100, Camera.PopoverArrowDirection.ARROW_ANY);
cameraPopoverHandle.setPosition(cameraPopoverOptions);
}
## CameraPopoverOptions
iOS-only parameters that specify the anchor element location and arrow
direction of the popover when selecting images from an iPad's library
or album.
{ x : 0,
y : 32,
width : 320,
height : 480,
arrowDir : Camera.PopoverArrowDirection.ARROW_ANY
};
### CameraPopoverOptions
- __x__: x pixel coordinate of screen element onto which to anchor the popover. _(Number)_
- __y__: y pixel coordinate of screen element onto which to anchor the popover. _(Number)_
- __width__: width, in pixels, of the screen element onto which to anchor the popover. _(Number)_
- __height__: height, in pixels, of the screen element onto which to anchor the popover. _(Number)_
- __arrowDir__: Direction the arrow on the popover should point. Defined in `Camera.PopoverArrowDirection` _(Number)_
Camera.PopoverArrowDirection = {
ARROW_UP : 1, // matches iOS UIPopoverArrowDirection constants
ARROW_DOWN : 2,
ARROW_LEFT : 4,
ARROW_RIGHT : 8,
ARROW_ANY : 15
};
Note that the size of the popover may change to adjust to the
direction of the arrow and orientation of the screen. Make sure to
account for orientation changes when specifying the anchor element
location.

# cordova-plugin-camera
Dieses Plugin definiert eine globale `navigator.camera`-Objekt, das eine API für Aufnahmen und für die Auswahl der Bilder aus dem System-Image-Library bietet.
Obwohl das Objekt mit der globalen Gültigkeitsbereich `navigator` verbunden ist, steht es nicht bis nach dem `Deviceready`-Ereignis.
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
## Installation
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
Nimmt ein Foto mit der Kamera, oder ein Foto aus dem Gerät Bildergalerie abgerufen. Das Bild wird an den Erfolg-Rückruf als base64-codierte `String` oder als URI für die Image-Datei übergeben. Die Methode selbst gibt ein `CameraPopoverHandle`-Objekt, das verwendet werden kann, um die Datei-Auswahl-Popover neu zu positionieren.
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### Beschreibung
Die `camera.getPicture`-Funktion öffnet das Gerät Standard-Kamera-Anwendung, die Benutzern ermöglicht, Bilder ausrichten. Dieses Verhalten tritt in der Standardeinstellung, wenn `Camera.sourceType` `Camera.PictureSourceType.CAMERA` entspricht. Sobald der Benutzer die Fotoschnäpper, die Kameraanwendung geschlossen wird und die Anwendung wird wiederhergestellt.
Wenn `Camera.sourceType` `Camera.PictureSourceType.PHOTOLIBRARY` oder `Camera.PictureSourceType.SAVEDPHOTOALBUM` ist, dann wird ein Dialogfeld angezeigt, das Benutzern ermöglicht, ein vorhandenes Bild auszuwählen. Die `camera.getPicture`-Funktion gibt ein `CameraPopoverHandle`-Objekt, das verwendet werden kann, um die Bild-Auswahl-Dialog, z. B. beim ändert sich der Orientierung des Geräts neu positionieren.
Der Rückgabewert wird an die `cameraSuccess`-Callback-Funktion in einem der folgenden Formate, je nach dem angegebenen `cameraOptions` gesendet:
* A `String` mit dem base64-codierte Foto-Bild.
* A `String` , die die Bild-Datei-Stelle auf lokalem Speicher (Standard).
Sie können tun, was Sie wollen, mit dem codierten Bildes oder URI, zum Beispiel:
* Rendern Sie das Bild in ein `<img>` Tag, wie im folgenden Beispiel
* Die Daten lokal zu speichern ( `LocalStorage` , [Lawnchair][1], etc..)
* Post die Daten an einen entfernten server
[1]: http://brianleroux.github.com/lawnchair/
**Hinweis**: Fotoauflösung auf neueren Geräten ist ganz gut. Fotos aus dem Gerät Galerie ausgewählt sind nicht zu einer niedrigeren Qualität herunterskaliert, selbst wenn ein `Qualität`-Parameter angegeben wird. Um Speicherprobleme zu vermeiden, legen Sie `Camera.destinationType` auf `FILE_URI` statt `DATA_URL`.
### Unterstützte Plattformen
* Amazon Fire OS
* Android
* BlackBerry 10
* Browser
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 und 8
* Windows 8
### "Einstellungen" (iOS)
* **CameraUsesGeolocation** (Boolean, Standardwert ist False). Zur Erfassung von JPEGs, auf true festgelegt, um Geolocation-Daten im EXIF-Header zu erhalten. Dies löst einen Antrag auf Geolocation-Berechtigungen, wenn auf True festgelegt.
<preference name="CameraUsesGeolocation" value="false" />
### Amazon Fire OS Macken
Amazon Fire OS verwendet Absichten zum Starten von der Kamera-Aktivität auf dem Gerät, um Bilder zu erfassen und auf Handys mit wenig Speicher, Cordova Tätigkeit getötet werden kann. In diesem Szenario kann das Bild nicht angezeigt, wenn die Aktivität von Cordova wiederhergestellt wird.
### Android Eigenarten
Android verwendet Absichten zum Starten von der Kamera-Aktivität auf dem Gerät, um Bilder zu erfassen und auf Handys mit wenig Speicher, Cordova Tätigkeit getötet werden kann. In diesem Szenario kann das Bild nicht angezeigt, wenn die Aktivität von Cordova wiederhergestellt wird.
### Browser-Eigenheiten
Fotos können nur als base64-codierte Bild zurückgeben werden.
### Firefox OS Macken
Kamera-Plugin ist derzeit implementiert mithilfe von [Web-Aktivitäten][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS Macken
Einschließlich einer JavaScript-`alert()` entweder Rückruffunktionen kann Probleme verursachen. Wickeln Sie die Warnung innerhalb eine `setTimeout()` erlauben die iOS-Bild-Picker oder Popover vollständig zu schließen, bevor die Warnung angezeigt:
setTimeout(function() {
// do your thing here!
}, 0);
### Windows Phone 7 Macken
Die native Kameraanwendung aufrufen, während das Gerät via Zune angeschlossen ist funktioniert nicht und löst eine Fehler-Callback.
### Tizen Macken
Tizen unterstützt nur ein `DestinationType` von `Camera.DestinationType.FILE_URI` und ein `SourceType` von `Camera.PictureSourceType.PHOTOLIBRARY`.
### Beispiel
Nehmen Sie ein Foto und rufen Sie sie als base64-codierte Bild:
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);
}
Nehmen Sie ein Foto und rufen Sie das Bild-Datei-Speicherort:
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);
}
## CameraOptions

El método se devuelve un `CameraPopoverHandle` objeto que puede utilizarse para volver a colocar el popover de selección de archivo.
navigator.camera.getPicture (cameraSuccess, cameraError, cameraOptions);
### Descripción
El `camera.getPicture` función abre la aplicación de cámara predeterminada del dispositivo que permite a los usuarios ajustar imágenes. Este comportamiento se produce de forma predeterminada, cuando `Camera.sourceType` es igual a `Camera.PictureSourceType.CAMERA` . Una vez que el usuario ajusta la foto, una aplicación de cámara se cierra y se restablecerá la aplicación.
Si `Camera.sourceType` es `Camera.PictureSourceType.PHOTOLIBRARY` o `Camera.PictureSourceType.SAVEDPHOTOALBUM` , entonces una muestra de diálogo que permite a los usuarios seleccionar una imagen existente. El `camera.getPicture` función devuelve un `CameraPopoverHandle` objeto, que puede utilizarse para volver a colocar el diálogo de selección de imagen, por ejemplo, cuando cambia la orientación del dispositivo.
El valor devuelto es enviado a la `cameraSuccess` función de callback, en uno de los formatos siguientes, dependiendo del objeto `cameraOptions` :
* Una `String` que contiene la imagen codificada en base64.
* Una `String` que representa la ubicación del archivo de imagen en almacenamiento local (por defecto).
Puedes hacer lo que quieras con la imagen codificada o URI, por ejemplo:
* Representar la imagen en una etiqueta de `<img>`, como en el ejemplo siguiente
* Guardar los datos localmente (`LocalStorage`, [Lawnchair][1], etc.)
* Enviar los datos a un servidor remoto
[1]: http://brianleroux.github.com/lawnchair/
**Nota**: resolución de la foto en los nuevos dispositivos es bastante bueno. Fotos seleccionadas de la Galería del dispositivo no son degradadas a una calidad más baja, incluso si un `quality` se especifica el parámetro. Para evitar problemas con la memoria común, establezca `Camera.destinationType` a `FILE_URI` en lugar de`DATA_URL`.
### Plataformas soportadas
* Amazon fire OS
* Android
* BlackBerry 10
* Explorador
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 y 8
* Windows 8
### Preferencias (iOS)
* **CameraUsesGeolocation** (booleano, el valor predeterminado de false). Para la captura de imágenes JPEG, establecido en true para obtener datos de geolocalización en la cabecera EXIF. Esto activará la solicitud de permisos de geolocalización si establecido en true.
<preference name="CameraUsesGeolocation" value="false" />
### Amazon fuego OS rarezas
Amazon fuego OS utiliza los intentos para poner en marcha la actividad de la cámara del dispositivo para capturar imágenes y en teléfonos con poca memoria, puede matar la actividad Cordova. En este escenario, la imagen no aparezca cuando se restaura la actividad cordova.
### Rarezas Android
Android utiliza los intentos para iniciar la actividad de la cámara del dispositivo para capturar imágenes, y en los teléfonos con poca memoria, puede matar la actividad Cordova. En este escenario, la imagen no aparezca cuando se restaura la actividad Cordova.
### Navegador rarezas
Sólo puede devolver fotos como imagen codificada en base64.
### Firefox OS rarezas
Cámara plugin actualmente se implementa mediante [Actividades Web][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS rarezas
Incluyendo un JavaScript `alert()` en cualquiera de la devolución de llamada funciones pueden causar problemas. Envuelva la alerta dentro de un `setTimeout()` para permitir que el selector de imagen iOS o popover cerrar completamente antes de la alerta se muestra:
setTimeout(function() {/ / Haz lo tuyo aquí!}, 0);
### Windows Phone 7 rarezas
Invocando la aplicación de cámara nativa mientras el dispositivo está conectado vía Zune no funciona y desencadena un callback de error.
### Rarezas Tizen
Tizen sólo es compatible con un `destinationType` de `Camera.DestinationType.FILE_URI` y un `sourceType` de`Camera.PictureSourceType.PHOTOLIBRARY`.
### Ejemplo
Tomar una foto y recuperarlo como una imagen codificada en base64:
navigator.camera.getPicture (onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.DATA_URL
});
function onSuccess(imageData) {var imagen = document.getElementById('myImage');
Image.src = "datos: image / jpeg; base64," + imageData;}
function onFail(message) {alert (' falló porque: ' + mensaje);}
Tomar una foto y recuperar la ubicación del archivo de la imagen:
navigator.camera.getPicture (onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.FILE_URI });
function onSuccess(imageURI) {var imagen = document.getElementById('myImage');
Image.src = imageURI;
} function onFail(message) {alert (' falló porque: ' + mensaje);}

# cordova-plugin-camera
Ce plugin définit un global `navigator.camera` objet qui fournit une API pour la prise de photos et de choisir des images de la bibliothèque d'images du système.
Bien que l'objet est attaché à la portée globale `navigator` , il n'est pas disponible jusqu'après la `deviceready` événement.
document.addEventListener (« deviceready », onDeviceReady, false) ;
function onDeviceReady() {console.log(navigator.camera);}
## Installation
Cordova plugin ajouter cordova-plugin-camera
## navigator.camera.getPicture
Prend une photo à l'aide de la caméra, ou récupère une photo de la Galerie d'images de l'appareil. L'image est passé au rappel succès comme un codage base64 `String` , ou comme l'URI du fichier de l'image. La méthode elle-même retourne un `CameraPopoverHandle` objet qui permet de repositionner le kangourou de sélection de fichier.
navigator.camera.getPicture (cameraSuccess, cameraError, cameraOptions) ;
### Description
Le `camera.getPicture` fonction ouvre l'application de caméra par défaut de l'appareil qui permet aux utilisateurs de prendre des photos. Ce comportement se produit par défaut, lorsque `Camera.sourceType` est égal à `Camera.PictureSourceType.CAMERA` . Une fois que l'utilisateur s'enclenche la photo, l'application appareil photo se ferme et l'application est restaurée.
Si `Camera.sourceType` est `Camera.PictureSourceType.PHOTOLIBRARY` ou `Camera.PictureSourceType.SAVEDPHOTOALBUM` , puis un dialogue affiche qui permet aux utilisateurs de sélectionner une image existante. Le `camera.getPicture` retourne un `CameraPopoverHandle` objet, ce qui permet de repositionner le dialogue de sélection d'image, par exemple, lorsque l'orientation de l'appareil change.
La valeur de retour est envoyée à la `cameraSuccess` la fonction de rappel, dans l'un des formats suivants, selon les `cameraOptions` :
* A `String` contenant l'image photo codée en base64.
* A `String` qui représente l'emplacement du fichier image sur le stockage local (par défaut).
Vous pouvez faire ce que vous voulez avec l'image codée ou URI, par exemple :
* Afficher l'image dans un `<img>` tag, comme dans l'exemple ci-dessous
* Enregistrer les données localement ( `LocalStorage` , [poids][1], etc..)
* Publier les données sur un serveur distant
[1]: http://brianleroux.github.com/lawnchair/
**NOTE**: la résolution de Photo sur les nouveaux appareils est assez bonne. Photos sélectionnées de la Galerie de l'appareil ne sont pas réduites à une baisse de la qualité, même si un `quality` paramètre est spécifié. Pour éviter les problèmes de mémoire commun, définissez `Camera.destinationType` à `FILE_URI` au lieu de`DATA_URL`.
### Plates-formes prises en charge
* Amazon Fire OS
* Android
* BlackBerry 10
* Navigateur
* Firefox OS
* iOS
* Paciarelli
* Windows Phone 7 et 8
* Windows 8
### Préférences (iOS)
* **CameraUsesGeolocation** (boolean, par défaut, false). Pour capturer des images JPEG, true pour obtenir des données de géolocalisation dans l'en-tête EXIF. Cela va déclencher une demande d'autorisations de géolocalisation si défini à true.
<preference name="CameraUsesGeolocation" value="false" />
### Amazon Fire OS Quirks
Amazon Fire OS utilise des intentions pour lancer l'activité de l'appareil photo sur l'appareil pour capturer des images et sur les téléphones avec peu de mémoire, l'activité de Cordova peut être tuée. Dans ce scénario, l'image peut ne pas apparaître lorsque l'activité de cordova est restaurée.
### Quirks Android
Android utilise des intentions pour lancer l'activité de l'appareil photo sur l'appareil pour capturer des images et sur les téléphones avec peu de mémoire, l'activité de Cordova peut être tuée. Dans ce scénario, l'image peut ne pas apparaître lorsque l'activité de Cordova est restaurée.
### Bizarreries navigateur
Peut retourner uniquement les photos comme image codée en base64.
### Firefox OS Quirks
Appareil photo plugin est actuellement mis en œuvre à l'aide [d'Activités sur le Web][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS Quirks
Y compris un JavaScript `alert()` dans les deux le rappel fonctions peuvent causer des problèmes. Envelopper l'alerte dans un `setTimeout()` pour permettre le sélecteur d'image iOS ou kangourou pour fermer entièrement avant que l'alerte s'affiche :
setTimeout(function() {/ / faire votre truc ici!}, 0) ;
### Windows Phone 7 Quirks
Invoquant l'application native caméra alors que l'appareil est connecté via Zune ne fonctionne pas et déclenche un rappel de l'erreur.
### Bizarreries de paciarelli
Paciarelli prend uniquement en charge un `destinationType` de `Camera.DestinationType.FILE_URI` et un `sourceType` de`Camera.PictureSourceType.PHOTOLIBRARY`.
### Exemple
Prendre une photo, puis extrayez-la comme une image codée en base64 :
navigator.camera.getPicture (onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.DATA_URL
}) ;
function onSuccess(imageData) {var image = document.getElementById('myImage') ;
image.src = "données : image / jpeg ; base64," + imageData;}
function onFail(message) {alert (' a échoué car: "+ message);}
Prendre une photo et récupérer l'emplacement du fichier de l'image :
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 (' a échoué car: "+ message);}
## CameraOptions
Paramètres optionnels pour personnaliser les réglages de l'appareil.

# cordova-plugin-camera
Questo plugin definisce un oggetto globale `navigator.camera`, che fornisce un'API per scattare foto e per aver scelto immagini dalla libreria di immagini del sistema.
Anche se l'oggetto è associato con ambito globale del `navigator`, non è disponibile fino a dopo l'evento `deviceready`.
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
## Installazione
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
Prende una foto utilizzando la fotocamera, o recupera una foto dalla galleria di immagini del dispositivo. L'immagine è passata al callback di successo come `String` con codifica base64, o come l'URI per il file di immagine. Lo stesso metodo restituisce un oggetto `CameraPopoverHandle` che può essere utilizzato per riposizionare il Muffin di selezione file.
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### Descrizione
La funzione `camera.getPicture` apre predefinito fotocamera applicazione il dispositivo che consente agli utenti di scattare foto. Questo comportamento si verifica per impostazione predefinita, quando `Camera.sourceType` è uguale a `Camera.PictureSourceType.CAMERA`. Una volta che l'utente scatta la foto, si chiude l'applicazione fotocamera e l'applicazione viene ripristinato.
Se `Camera.sourceType` è `Camera.PictureSourceType.PHOTOLIBRARY` o `Camera.PictureSourceType.SAVEDPHOTOALBUM`, una finestra di dialogo Visualizza che permette agli utenti di selezionare un'immagine esistente. La funzione `camera.getPicture` restituisce un oggetto `CameraPopoverHandle` che può essere utilizzato per riposizionare la finestra di selezione immagine, ad esempio, quando l'orientamento del dispositivo.
Il valore restituito viene inviato alla funzione di callback `cameraSuccess`, in uno dei seguenti formati, a seconda il `cameraOptions` specificato:
* A `String` contenente l'immagine della foto con codifica base64.
* A `String` che rappresenta il percorso del file di immagine su archiviazione locale (predefinito).
Si può fare quello che vuoi con l'immagine codificata o URI, ad esempio:
* Il rendering dell'immagine in un `<img>` tag, come nell'esempio qui sotto
* Salvare i dati localmente ( `LocalStorage` , [Lawnchair][1], ecc.)
* Inviare i dati a un server remoto
[1]: http://brianleroux.github.com/lawnchair/
**Nota**: risoluzione foto sui più recenti dispositivi è abbastanza buona. Foto selezionate dalla galleria del dispositivo non è percepiranno di qualità inferiore, anche se viene specificato un parametro di `quality`. Per evitare problemi di memoria comune, impostare `Camera.destinationType` `FILE_URI` piuttosto che `DATA_URL`.
### Piattaforme supportate
* Amazon fuoco OS
* Android
* BlackBerry 10
* Browser
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 e 8
* Windows 8
### Preferenze (iOS)
* **CameraUsesGeolocation** (boolean, default è false). Per l'acquisizione di immagini JPEG, impostato su true per ottenere dati di geolocalizzazione nell'intestazione EXIF. Questo innescherà una richiesta per le autorizzazioni di geolocalizzazione, se impostato su true.
<preference name="CameraUsesGeolocation" value="false" />
### Amazon fuoco OS stranezze
Amazon fuoco OS utilizza intenti a lanciare l'attività della fotocamera sul dispositivo per catturare immagini e sui telefoni con poca memoria, l'attività di Cordova può essere ucciso. In questo scenario, l'immagine potrebbe non apparire quando viene ripristinata l'attività di cordova.
### Stranezze Android
Android utilizza intenti a lanciare l'attività della fotocamera sul dispositivo per catturare immagini e sui telefoni con poca memoria, l'attività di Cordova può essere ucciso. In questo scenario, l'immagine potrebbe non apparire quando viene ripristinata l'attività di Cordova.
### Stranezze browser
Può restituire solo la foto come immagine con codifica base64.
### Firefox OS stranezze
Fotocamera plugin è attualmente implementato mediante [Web Activities][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS stranezze
Compreso un JavaScript `alert()` in una delle funzioni di callback può causare problemi. Avvolgere l'avviso all'interno di un `setTimeout()` per consentire la selezione immagine iOS o muffin per chiudere completamente la prima che viene visualizzato l'avviso:
setTimeout(function() {
// do your thing here!
}, 0);
### Windows Phone 7 stranezze
Richiamando l'applicazione nativa fotocamera mentre il dispositivo è collegato tramite Zune non funziona e innesca un callback di errore.
### Tizen stranezze
Tizen supporta solo a `destinationType` di `Camera.DestinationType.FILE_URI` e un `sourceType` di `Camera.PictureSourceType.PHOTOLIBRARY`.
### Esempio
Scattare una foto e recuperarla come un'immagine con codifica base64:
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);
}
Scattare una foto e recuperare il percorso del file dell'immagine:
navigator.camera.getPicture(onSuccess, onFail, { quality: 50,
destinationType: Camera.DestinationType.FILE_URI });
function onSuccess(imageURI) {
var image = document.getElementById('myImage');
image.src = imageURI;

VIDEO: 1, // allow selection of video only, WILL ALWAYS RETURN FILE_URI
ALLMEDIA : 2 // allow selection from all media types
};
* **correctOrientation**: ruotare l'immagine per correggere l'orientamento del dispositivo durante l'acquisizione. *(Booleano)*

### iOS stranezze
* Impostare `quality` inferiore al 50 per evitare errori di memoria su alcuni dispositivi.
* Quando si utilizza `destinationType.FILE_URI` , foto vengono salvati nella directory temporanea dell'applicazione. Il contenuto della directory temporanea dell'applicazione viene eliminato quando l'applicazione termina.
### Tizen stranezze
* opzioni non supportate
* restituisce sempre un URI del FILE
### Windows Phone 7 e 8 stranezze
* Ignora il `allowEdit` parametro.
* Ignora il `correctOrientation` parametro.
* Ignora il `cameraDirection` parametro.
* Ignora il `saveToPhotoAlbum` parametro. IMPORTANTE: Tutte le immagini scattate con la fotocamera di cordova wp7/8 API vengono sempre copiate rotolo fotocamera del telefono cellulare. A seconda delle impostazioni dell'utente, questo potrebbe anche significare che l'immagine viene caricato in automatico a loro OneDrive. Questo potenzialmente potrebbe significare che l'immagine è disponibile a un pubblico più ampio di app destinate. Se questo un blocco dell'applicazione, sarà necessario implementare il CameraCaptureTask come documentato su msdn: <http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394006.aspx> si può anche commentare o up-voto la questione correlata nel [tracciatore di problemi][3]
* Ignora la `mediaType` proprietà di `cameraOptions` come il SDK di Windows Phone non fornisce un modo per scegliere il video da PHOTOLIBRARY.

# cordova-plugin-camera
このプラグインは、写真を撮るため、システムのイメージ ライブラリからイメージを選択するために API を提供します、グローバル `navigator.camera` オブジェクトを定義します。
オブジェクトは、グローバル スコープの `ナビゲーター` に添付、それがないまで `deviceready` イベントの後。
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
## インストール
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
カメラを使用して写真を取るか、デバイスの画像ギャラリーから写真を取得します。 イメージが渡されます成功時のコールバックを base64 エンコードされた `文字列`、または、URI としてイメージ ファイル。 メソッド自体はファイル選択ポップ オーバーの位置を変更するために使用できる `CameraPopoverHandle` オブジェクトを返します。
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### 解説
`camera.getPicture` 関数は、ユーザーの写真をスナップすることができますデバイスのデフォルト カメラ アプリケーションを開きます。 `Camera.sourceType``Camera.PictureSourceType.CAMERA` と等しい場合既定では、この現象が発生します。 ユーザーは写真をスナップ、カメラ アプリケーションを閉じるし、アプリケーションが復元されます。
`Camera.sourceType` `Camera.PictureSourceType.PHOTOLIBRARY` または `Camera.PictureSourceType.SAVEDPHOTOALBUM` の場合、ダイアログ ボックスはユーザーを既存のイメージを選択することができますが表示されます。 `camera.getPicture` 関数は、デバイスの向きが変更されたとき、たとえば、イメージの選択ダイアログには、位置を変更するために使用することができます、`CameraPopoverHandle` オブジェクトを返します。
戻り値が `cameraSuccess` コールバック関数の指定 `cameraOptions` に応じて、次の形式のいずれかに送信されます。
* A `String` 写真の base64 でエンコードされたイメージを含んでいます。
* A `String` (既定値) のローカル記憶域上のイメージ ファイルの場所を表します。
自由に変更、エンコードされたイメージ、または URI などを行うことができます。
* イメージをレンダリングする `<img>` 以下の例のように、タグ
* ローカル データの保存 ( `LocalStorage` 、 [Lawnchair][1]など)。
* リモート サーバーにデータを投稿します。
[1]: http://brianleroux.github.com/lawnchair/
**注**: 新しいデバイス上の写真の解像度はかなり良いです。 デバイスのギャラリーから選択した写真は `quality` パラメーターが指定されて場合でも下方の品質に縮小されません。 一般的なメモリの問題を避けるために `DATA_URL` ではなく `FILE_URI``Camera.destinationType` を設定します。.
### サポートされているプラットフォーム
* アマゾン火 OS
* アンドロイド
* ブラックベリー 10
* ブラウザー
* Firefox の OS
* iOS
* Tizen

# cordova-plugin-camera
이 플러그인 시스템의 이미지 라이브러리에서 이미지를 선택 및 사진 촬영을 위한 API를 제공 하는 글로벌 `navigator.camera` 개체를 정의 합니다.
개체 `navigator` 글로벌 범위 첨부 아니에요 때까지 사용할 수 있는 `deviceready` 이벤트 후.
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
## 설치
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
카메라를 사용 하 여 사진을 걸립니다 또는 소자의 이미지 갤러리에서 사진을 검색 합니다. 이미지는 성공 콜백에 전달 base64 인코딩된 `문자열` 또는 URI로 이미지 파일에 대 한. 방법 자체는 파일 선택 popover 위치를 사용할 수 있는 `CameraPopoverHandle` 개체를 반환 합니다.
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### 설명
`Camera.getPicture` 함수 스냅 사진을 사용자가 소자의 기본 카메라 응용 프로그램을 엽니다. 이 문제는 `Camera.sourceType` `Camera.PictureSourceType.CAMERA` 경우 기본적으로 발생 합니다. 일단 사용자 스냅 사진, 카메라 응용 프로그램 종료 하 고 응용 프로그램 복원 됩니다.
`Camera.sourceType``Camera.PictureSourceType.PHOTOLIBRARY` 또는 `Camera.PictureSourceType.SAVEDPHOTOALBUM`, 대화 상자가 사용자가 기존 이미지를 선택할 수 있도록 표시 됩니다. `camera.getPicture` 함수는 장치 방향 변경 될 때 이미지 선택 대화 상자, 예를 들어, 위치를 변경 하려면 사용할 수 있는 `CameraPopoverHandle` 개체를 반환 합니다.
반환 값은 `cameraSuccess` 콜백 함수 지정된 `cameraOptions`에 따라 다음 형식 중 하나에 전송 됩니다.
* A `String` base64 인코딩된 사진 이미지를 포함 합니다.
* A `String` 로컬 저장소 (기본값)의 이미지 파일 위치를 나타내는.
할 수 있는 당신이 원하는대로 인코딩된 이미지 또는 URI, 예를 들면:
* 렌더링 이미지는 `<img>` 아래 예제와 같이 태그
* 로컬로 데이터를 저장 ( `LocalStorage` , [Lawnchair][1], 등.)
* 원격 서버에 데이터 게시
[1]: http://brianleroux.github.com/lawnchair/
**참고**: 더 새로운 장치에 사진 해상도 아주 좋은. 소자의 갤러리에서 선택 된 사진 `품질` 매개 변수를 지정 하는 경우에 낮은 품질에 관하여 하지는. 일반적인 메모리 문제를 피하기 위해 `DATA_URL` 보다 `FILE_URI` `Camera.destinationType` 설정.

# cordova-plugin-camera
Ten plugin definiuje obiekt globalny `navigator.camera`, który dostarcza API do robienia zdjęć i wybór zdjęć z biblioteki obrazów systemu.
Mimo, że obiekt jest dołączony do globalnego zakresu `navigator`, to nie dostępne dopiero po zdarzeniu `deviceready`.
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
## Instalacja
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
Ma zdjęcia za pomocą aparatu, lub pobiera zdjęcia z urządzenia Galeria zdjęć. Obraz jest przekazywany do wywołania zwrotnego sukces jako kodowane algorytmem base64 `ciąg`, lub identyfikator URI dla pliku obrazu. Sama metoda zwraca obiekt `CameraPopoverHandle`, który może służyć do zmiany położenia pliku wyboru popover.
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### Opis
Funkcja `camera.getPicture` otwiera urządzenia domyślnej aplikacji aparat fotograficzny ów pozwala użytkownik wobec chwycić zębami kino. To zachowanie występuje domyślnie, gdy `Camera.sourceType` jest równa `Camera.PictureSourceType.CAMERA`. Gdy użytkownik zaskoczy zdjęcie, ten aparat fotograficzny applicationâ zamyka i aplikacji jest przywracany.
Jeśli `Camera.sourceType` jest równe `Camera.PictureSourceType.PHOTOLIBRARY` lub `Camera.PictureSourceType.SAVEDPHOTOALBUM`, wtedy zostanie wyświetlone okno dialogowe pozwalające użytkownikowi na wybór istniejącego obrazu. Funkcja `camera.getPicture` zwraca obiekt `CameraPopoverHandle`, który obsługuje zmianę położenia okna wyboru obrazu, np. po zmianie orientacji urządzenia.
Zwracana wartość jest wysyłany do funkcji wywołania zwrotnego `cameraSuccess`, w jednym z następujących formatów, w zależności od określonego `cameraOptions`:
* `String` zawierający obraz zakodowany przy pomocy base64.
* `String` reprezentujący lokalizację pliku obrazu w lokalnym magazynie (domyślnie).
Może rób, co chcesz z zakodowany obraz lub identyfikatora URI, na przykład:
* Przedstawić obraz w tagu `<img>`, jak w przykładzie poniżej
* Zapisać lokalnie dane (`LocalStorage`, [Lawnchair][1], etc.)
* Wysłać dane na zdalny serwer
[1]: http://brianleroux.github.com/lawnchair/
**Uwaga**: zdjęcie rozdzielczości na nowsze urządzenia jest bardzo dobry. Zdjęcia wybrane z galerii urządzenia są nie przeskalowanych w dół do niższej jakości, nawet jeśli określono parametr `quality`. Aby uniknąć typowych problemów z pamięci, zestaw `Camera.destinationType` `FILE_URI` zamiast `DATA_URL`.
### Obsługiwane platformy
* Amazon Fire OS
* Android
* BlackBerry 10
* Przeglądarka
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 i 8
* Windows 8
### Preferencje (iOS)
* **CameraUsesGeolocation** (boolean, wartość domyślna to false). Do przechwytywania JPEG, zestaw do true, aby uzyskać danych geolokalizacyjnych w nagłówku EXIF. To spowoduje wniosek o geolokalizacji uprawnienia, jeśli zestaw na wartość true.
<preference name="CameraUsesGeolocation" value="false" />
### Amazon ogień OS dziwactwa
Amazon ogień OS używa intencje do rozpoczęcia działalności aparatu na urządzenie do przechwytywania obrazów, i na telefony z pamięci, Cordova aktywność może zostać zabity. W tym scenariuszu obraz mogą nie być wyświetlane po przywróceniu aktywności cordova.
### Dziwactwa Androida
Android używa intencje do rozpoczęcia działalności aparatu na urządzenie do przechwytywania obrazów, i na telefony z pamięci, Cordova aktywność może zostać zabity. W tym scenariuszu obraz mogą nie być wyświetlane po przywróceniu aktywności Cordova.
### Quirks przeglądarki
Może zwracać tylko zdjęcia jako obraz w formacie algorytmem base64.
### Firefox OS dziwactwa
Aparat plugin jest obecnie implementowane za pomocą [Działania sieci Web][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### Dziwactwa iOS
W jednej z funkcji wywołania zwrotnego w tym JavaScript `alert()` może powodować problemy. Owinąć w `setTimeout()` umożliwia wybór obrazu iOS lub popover całkowicie zamknąć zanim wyświetli alert alert:
setTimeout(function() {
// do your thing here!
}, 0);
### Dziwactwa Windows Phone 7
Wywoływanie aparat native aplikacji, podczas gdy urządzenie jest podłączone przez Zune nie działa i powoduje błąd wywołania zwrotnego.
### Dziwactwa Tizen
Tizen obsługuje tylko `destinationType` z `Camera.DestinationType.FILE_URI` i `sourceType` z `Camera.PictureSourceType.PHOTOLIBRARY`.
### Przykład
Zrób zdjęcie i pobrać go jako kodowane algorytmem base64 obrazu:
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);
}
Zrób zdjęcie i pobrać lokalizacji pliku obrazu:
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);
}
## CameraOptions
Opcjonalne parametry, aby dostosować ustawienia aparatu.
{ quality : 75,
destinationType : Camera.DestinationType.DATA_URL,
sourceType : Camera.PictureSourceType.CAMERA,
allowEdit : true,
encodingType: Camera.EncodingType.JPEG,
targetWidth: 100,
targetHeight: 100,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false };
### Opcje
* **quality**: Jakość zapisywanego obrazu, wyrażona w przedziale 0-100, gdzie 100 zazwyczaj jest maksymalną rozdzielczością bez strat w czasie kompresji pliku. Wartością domyślną jest 50. *(Liczba)* (Pamiętaj, że informacja o rozdzielczości aparatu jest niedostępna.)
* **destinationType**: Wybierz format zwracanej wartości. Wartością domyślną jest FILE_URI. Zdefiniowane w `navigator.camera.DestinationType` *(numer)*
Camera.DestinationType = {
DATA_URL : 0, // Return image as base64-encoded string
FILE_URI : 1, // Return image file URI
NATIVE_URI : 2 // Return image native URI (e.g., assets-library:// on iOS or content:// on Android)

};
* **targetWidth**: Szerokość w pikselach skalowanego obrazu. Musi być użyte z **targetHeight**. Współczynnik proporcji pozostaje stały. *(Liczba)*
* **targetHeight**: Wysokość w pikselach skalowanego obrazu. Musi być użyte z **targetWidth**. Współczynnik proporcji pozostaje stały. *(Liczba)*
* **mediaType**: Ustawia typ nośnika, z którego będzie wybrany. Działa tylko wtedy, gdy `PictureSourceType` jest `PHOTOLIBRARY` lub `SAVEDPHOTOALBUM`. Zdefiniowane w `nagivator.camera.MediaType` *(Liczba)*
Camera.MediaType = {
PICTURE: 0, // allow selection of still pictures only. DEFAULT. Will return format specified via DestinationType
VIDEO: 1, // allow selection of video only, WILL ALWAYS RETURN FILE_URI
ALLMEDIA : 2 // allow selection from all media types
};
* **correctOrientation**: Obraca obraz aby skorygować orientację urządzenia podczas przechwytywania. *(Boolean)*
* **saveToPhotoAlbum**: Po przechwyceniu zapisuje na urządzeniu obraz w albumie na zdjęcia. *(Boolean)*
* **popoverOptions**: Opcja tylko dla platformy iOS, która określa położenie wyskakującego okna na iPadzie. Zdefiniowane w `CameraPopoverOptions`.
* **cameraDirection**: Wybierz aparat do korzystania (lub z powrotem przodem). Wartością domyślną jest z powrotem. Zdefiniowane w `navigator.camera.Direction` *(numer)*
Camera.Direction = {
BACK : 0, // Use the back-facing camera
FRONT : 1 // Use the front-facing camera
};
### Amazon ogień OS dziwactwa
* Jakakolwiek wartość w `cameraDirection` skutkuje użyciem tylnej kamery.
* Parametr `allowEdit` jest ignorowany.
* Oba parametry `Camera.PictureSourceType.PHOTOLIBRARY` oraz `Camera.PictureSourceType.SAVEDPHOTOALBUM` wyświetlają ten sam album ze zdjęciami.
### Dziwactwa Androida
* Jakakolwiek wartość w `cameraDirection` skutkuje użyciem tylnej kamery.
* Parametr `allowEdit` jest ignorowany.
* Oba parametry `Camera.PictureSourceType.PHOTOLIBRARY` oraz `Camera.PictureSourceType.SAVEDPHOTOALBUM` wyświetlają ten sam album ze zdjęciami.
### Jeżyna 10 dziwactwa
* Parametr `quality` jest ignorowany.
* Parametr `allowEdit` jest ignorowany.
* Nie jest wspierane `Camera.MediaType`.
* Parametr `correctOrientation` jest ignorowany.
* Parametr `cameraDirection` jest ignorowany.
### Firefox OS dziwactwa
* Parametr `quality` jest ignorowany.
* `Camera.DestinationType`jest ignorowane i jest równa `1` (plik obrazu URI)
* Parametr `allowEdit` jest ignorowany.
* Ignoruje `PictureSourceType` parametr (użytkownik wybiera go w oknie dialogowym)
* Ignoruje`encodingType`
* Ignoruje `targetWidth` i`targetHeight`
* Nie jest wspierane `Camera.MediaType`.
* Parametr `correctOrientation` jest ignorowany.
* Parametr `cameraDirection` jest ignorowany.
### Dziwactwa iOS
* Ustaw `quality` poniżej 50 aby uniknąć błędów pamięci na niektórych urządzeniach.
* Podczas korzystania z `destinationType.FILE_URI` , zdjęcia są zapisywane w katalogu tymczasowego stosowania. Zawartość katalogu tymczasowego stosowania jest usuwany po zakończeniu aplikacji.
### Dziwactwa Tizen
* opcje nie są obsługiwane
* zawsze zwraca FILE URI
### Windows Phone 7 i 8 dziwactwa
* Parametr `allowEdit` jest ignorowany.
* Parametr `correctOrientation` jest ignorowany.
* Parametr `cameraDirection` jest ignorowany.
* Ignoruje `saveToPhotoAlbum` parametr. Ważne: Wszystkie zdjęcia zrobione aparatem wp7/8 cordova API są zawsze kopiowane do telefonu w kamerze. W zależności od ustawień użytkownika może to też oznaczać że obraz jest automatycznie przesłane do ich OneDrive. Potencjalnie może to oznaczać, że obraz jest dostępne dla szerszego grona odbiorców niż Twoja aplikacja przeznaczona. Jeśli ten bloker aplikacji, trzeba będzie wdrożenie CameraCaptureTask, opisane na msdn: <http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394006.aspx> można także komentarz lub górę głosowanie powiązanych kwestii w [śledzenia błędów][3]
* Ignoruje `mediaType` Właściwość `cameraOptions` jako SDK Windows Phone nie umożliwiają wybór filmów z PHOTOLIBRARY.

# cordova-plugin-camera
Этот плагин предоставляет API для съемки и для выбора изображения из библиотеки изображений системы.
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
Снимает фотографию с помощью камеры, или получает фотографию из галереи изображений устройства. Изображение передается на функцию обратного вызова успешного завершения как `String` в base64-кодировке, или как URI указывающего на файл изображения. Метод возвращает объект `CameraPopoverHandle`, который может использоваться для перемещения инструмента выбора файла.
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### Описание
Функция `camera.getPicture` открывает приложение камеры устройства, которое позволяет снимать фотографии. Это происходит по умолчанию, когда `Camera.sourceType` равно `Camera.PictureSourceType.CAMERA` . Как только пользователь делает снимок,приложение камеры закрывается и приложение восстанавливается.
Если `Camera.sourceType` является `Camera.PictureSourceType.PHOTOLIBRARY` или `Camera.PictureSourceType.SAVEDPHOTOALBUM` , то показывается диалоговое окно, которое позволяет пользователям выбрать существующее изображение. Функция `camera.getPicture` возвращает объект `CameraPopoverHandle` объект, который может использоваться для перемещения диалога выбора изображения, например, при изменении ориентации устройства.
Возвращаемое значение отправляется в функцию обратного вызова `cameraSuccess` в одном из следующих форматов, в зависимости от параметра `cameraOptions` :
* A объект `String` содержащий фото изображение в base64-кодировке.
* Объект `String` представляющий расположение файла изображения на локальном хранилище (по умолчанию).
Вы можете сделать все, что угодно вы хотите с закодированным изображением или URI, например:
* Отобразить изображение с помощью тега `<img>`, как показано в примере ниже
* Сохранять данные локально (`LocalStorage`, [Lawnchair][1], и т.д.)
* Отправлять данные на удаленный сервер
[1]: http://brianleroux.github.com/lawnchair/
**Примечание**: разрешение фото на более новых устройствах является достаточно хорошим. Фотографии из галереи устройства не масштабируются к более низкому качеству, даже если указан параметр `quality`. Чтобы избежать общих проблем с памятью, установите `Camera.destinationType` в `FILE_URI` вместо `DATA_URL`.
### Поддерживаемые платформы
* Amazon Fire OS
* Android
* BlackBerry 10
* Обозреватель
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 и 8
* Windows 8
### Предпочтения (iOS)
* **CameraUsesGeolocation** (логическое значение, по умолчанию false). Для захвата изображения JPEG, значение true, чтобы получить данные геопозиционирования в заголовке EXIF. Это вызовет запрос на разрешения геолокации, если задано значение true.
<preference name="CameraUsesGeolocation" value="false" />
### Особенности Amazon Fire OS
Amazon Fire OS используют намерения для запуска активности камеры на устройстве для съемки фотографий, и на устройствах с низким объемам памяти, активность Cordova может быть завершена. В этом случае изображение может не появиться при восстановлении активности Cordova.
### Особенности Android
Android используют намерения для запуска активности камеры на устройстве для съемки фотографий, и на устройствах с низким объемам памяти, активность Cordova может быть завершена. В этом случае изображение может не появиться при восстановлении активности Cordova.
### Браузер причуды
Может возвращать только фотографии как изображения в кодировке base64.
### Особенности Firefox OS
Плагин Camera на данный момент реализован с использованием [Web Activities][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### Особенности iOS
Включение функции JavaScript `alert()` в любой из функций обратного вызова функции может вызвать проблемы. Оберните вызов alert в `setTimeout()` для позволения окну выбора изображений iOS полностью закрыться перед отображение оповещения:
setTimeout(function() {/ / ваши вещи!}, 0);
### Особенности Windows Phone 7
Вызов встроенного приложения камеры, в то время как устройство подключено к Zune не работает, и инициирует обратный вызов для ошибки.
### Особенности Tizen
Tizen поддерживает только значение `destinationType` равное `Camera.DestinationType.FILE_URI` и значение `sourceType` равное `Camera.PictureSourceType.PHOTOLIBRARY`.
### Пример
Сделайте фотографию и получите его как изображение в base64-кодировке:
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);
}
Сделайте фотографию и получить расположение файла с изображением:
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);
}
## CameraOptions
Необязательные параметры для настройки параметров камеры.
{ quality : 75,
destinationType : Camera.DestinationType.DATA_URL,
sourceType : Camera.PictureSourceType.CAMERA,
allowEdit : true,
encodingType: Camera.EncodingType.JPEG,

Camera.EncodingType = {
JPEG: 0, // возвращает изображение в формате JPEG
PNG: 1 // возвращает рисунок в формате PNG
};
* **targetWidth**: ширина изображения в пикселах к которой необходимо осуществить масштабирование. Это значение должно использоваться совместно с **targetHeight**. Пропорции изображения останутся неизменными. *(Число)*
* **targetHeight**: высота изображения в пикселах к которой необходимо осуществить масштабирование. Это значение должно использоваться совместно с **targetWidth**. Пропорции изображения останутся неизменными. *(Число)*
* **тип носителя**: Установите источник получения изображения, из которого надо выбрать изображение. Работает только если `PictureSourceType` равно `PHOTOLIBRARY` или `SAVEDPHOTOALBUM` . Определяется в `nagivator.camera.MediaType` *(число)*
Camera.MediaType = {
PICTURE: 0, / / разрешить выбор только сохраненных изображений. DEFAULT. Will return format specified via DestinationType
VIDEO: 1, // allow selection of video only, WILL ALWAYS RETURN FILE_URI
ALLMEDIA : 2 // allow selection from all media types
};
* **correctOrientation**: вращает изображение, чтобы внести исправления к ориентации устройства во время захвата. *(Логический)*
* **saveToPhotoAlbum**: сохранить изображение в фотоальбом на устройстве после захвата. *(Логическое)*
* **popoverOptions**: только для iOS параметры, которые определяют местоположение инструмента в iPad. Определены в`CameraPopoverOptions`.
* **cameraDirection**: выбрать камеру для использования (передней или задней стороне). Значение по умолчанию — обратно. Определяется в `navigator.camera.Direction` *(число)*
Camera.Direction = {
BACK : 0, // Use the back-facing camera
FRONT : 1 // Use the front-facing camera
};
### Особенности Amazon Fire OS
* Любое значение `cameraDirection` возвращает фотографию сделанную задней камерой.
* Игнорирует параметр `allowEdit`.
* Оба параметра `Camera.PictureSourceType.PHOTOLIBRARY` и `Camera.PictureSourceType.SAVEDPHOTOALBUM` отображают один и тот же фотоальбом.
### Особенности Android
* Любое значение `cameraDirection` возвращает фотографию сделанную задней камерой.
* Игнорирует параметр `allowEdit`.
* Оба параметра `Camera.PictureSourceType.PHOTOLIBRARY` и `Camera.PictureSourceType.SAVEDPHOTOALBUM` отображают один и тот же фотоальбом.
### Особенности BlackBerry 10
* Игнорирует `quality` параметр.
* Игнорирует параметр `allowEdit`.
* `Camera.MediaType` не поддерживается.
* Игнорирует параметр `correctOrientation`.
* Игнорирует параметр `cameraDirection`.
### Особенности Firefox OS
* Игнорирует `quality` параметр.
* Значение `Camera.DestinationType` игнорируется и равно `1` (URI для файла изображения)
* Игнорирует параметр `allowEdit`.
* Игнорирует параметр `PictureSourceType` (пользователь выбирает его в диалоговом окне)
* Игнорирует параметр `encodingType`
* Игнорирует `targetWidth` и `targetHeight`
* `Camera.MediaType` не поддерживается.
* Игнорирует параметр `correctOrientation`.
* Игнорирует параметр `cameraDirection`.
### Особенности iOS
* Установите `quality` ниже 50, для того чтобы избежать ошибок памяти на некоторых устройствах.
* При использовании `destinationType.FILE_URI` , фотографии сохраняются во временном каталоге приложения. Содержимое приложения временного каталога удаляется при завершении приложения.
### Особенности Tizen
* options, не поддерживается
* всегда возвращает URI файла
### Особенности Windows Phone 7 и 8
* Игнорирует параметр `allowEdit`.
* Игнорирует параметр `correctOrientation`.
* Игнорирует параметр `cameraDirection`.
* Игнорирует `saveToPhotoAlbum` параметр. Важно: Все изображения, снятые камерой wp7/8 cordova API всегда копируются в рулон камеры телефона. В зависимости от параметров пользователя это также может означать, что изображение автоматически загружены на их OneDrive. Потенциально это может означать, что этот образ доступен для более широкой аудитории, чем ваше приложение предназначено. Если этот блокатор для вашего приложения, вам нужно будет осуществить CameraCaptureTask, как описано на сайте msdn: <http://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394006.aspx> вы можете также комментарий или вверх голосование связанный с этим вопрос [отслеживания][3]
* Игнорирует свойство `mediaType` объекта `cameraOptions` так как Windows Phone SDK не предоставляет способ выбрать видео из PHOTOLIBRARY.

# cordova-plugin-camera
這個外掛程式定義了一個全球 `navigator.camera` 物件,它提供了 API拍照從系統的圖像庫中選擇圖像。
雖然該物件附加到全球範圍內 `導航器`,它不可用直到 `deviceready` 事件之後。
document.addEventListener("deviceready", onDeviceReady, false);
function onDeviceReady() {
console.log(navigator.camera);
}
## 安裝
cordova plugin add cordova-plugin-camera
## navigator.camera.getPicture
需要一張照片,使用相機,或從設備的圖像庫檢索一張照片。 圖像被傳遞給成功回檔的 base64 編碼 `String`,或作為 URI 為影像檔。 該方法本身返回一個 `CameraPopoverHandle` 物件,它可以用來重新置放檔選擇氣泡框。
navigator.camera.getPicture( cameraSuccess, cameraError, cameraOptions );
### 說明
`camera.getPicture` 函數打開該設備的預設攝像頭應用程式,允許使用者拍照。 `Camera.sourceType` 等於 `Camera.PictureSourceType.CAMERA` 時,預設情況下,發生此行為。 一旦使用者打斷了他的照片,相機應用程式關閉,且應用程式還原。
如果 `Camera.sourceType``Camera.PictureSourceType.PHOTOLIBRARY``Camera.PictureSourceType.SAVEDPHOTOALBUM`,然後顯示一個對話方塊,允許使用者選擇一個現有的圖像。 `camera.getPicture` 函數返回一個 `CameraPopoverHandle` 物件,它可以用於重新置放圖像選擇的對話方塊,例如,當設備的方向變化。
傳回值是發送到 `cameraSuccess` 回呼函數中,在以下的格式,具體取決於指定的 `cameraOptions` 之一:
* A `String` 包含的 base64 編碼的照片圖像。
* A `String` 表示在本機存放區 (預設值) 上的影像檔位置。
你可以做任何你想要的編碼的圖像或 URI例如
* 呈現在圖像 `<img>` 標記,如下面的示例所示
* 保存本地的資料 `LocalStorage` [Lawnchair][1],等等.)
* 將資料發佈到遠端伺服器
[1]: http://brianleroux.github.com/lawnchair/
**注** 在更新設備上的照片解析度是很好。 選擇從設備的庫的照片是不壓縮螢幕使其以較低的品質,即使指定了一個 `quality` 參數。 要避免常見的記憶體問題,請將 `Camera.destinationType` 設置為 `FILE_URI`,而不是 `DATA_URL`.
### 支援的平臺
* 亞馬遜火 OS
* Android 系統
* 黑莓 10
* 瀏覽器
* 火狐瀏覽器的作業系統
* iOS
*
* Windows Phone 7 和 8
* Windows 8
### 首選項 iOS
* **CameraUsesGeolocation**(布林值,預設值為 false。 用於捕獲 jpeg 檔,設置為 true以在 EXIF 頭資訊中獲取地理定位資料。 這將觸發請求的地理位置的許可權,如果設置為 true。
<preference name="CameraUsesGeolocation" value="false" />
### 亞馬遜火 OS 怪癖
亞馬遜火 OS 使用意圖啟動相機活動設備來捕捉圖像上, 和手機上記憶體不足,科爾多瓦活動可能被殺害。 在這種情況下,可能不會顯示圖像時恢復了科爾多瓦活動。
### Android 的怪癖
Android 使用意圖以啟動相機活動設備來捕捉圖像上, 和手機上記憶體不足,科爾多瓦活動可能被殺害。 在這種情況下,可能不會顯示圖像時恢復了科爾多瓦活動。
### 瀏覽器的怪癖
可以只返回照片作為 base64 編碼的圖像。
### 火狐瀏覽器作業系統的怪癖
觀景窗外掛程式目前實施使用 [Web 活動][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS 的怪癖
包括 JavaScript `alert ()` 中的回呼函數會導致問題。 包裝內 `setTimeout()` 允許 iOS 圖像選取器或氣泡框以完全關閉之前,警報將顯示警報:
setTimeout(function() {
// do your thing here!
}, 0);
### Windows Phone 7 的怪癖
調用本機攝像頭應用程式,而通過 Zune 所連接的設備不能工作,並且觸發錯誤回檔。
### 泰怪癖
泰只支援 `destinationType``Camera.DestinationType.FILE_URI``Camera.PictureSourceType.PHOTOLIBRARY``sourceType`.
### 示例
拍一張照片,並檢索它作為一個 base64 編碼的圖像:
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);
}
拍一張照片和檢索圖像的檔位置:
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);
}
## CameraOptions
要自訂相機設置的可選參數。
{ quality : 75,
destinationType : Camera.DestinationType.DATA_URL,
sourceType : Camera.PictureSourceType.CAMERA,
allowEdit : true,
encodingType: Camera.EncodingType.JPEG,
targetWidth: 100,
targetHeight: 100,
popoverOptions: CameraPopoverOptions,
saveToPhotoAlbum: false };
### 選項
* **品質** 保存的圖像,表示為範圍 0-100100是通常全解析度無損失從檔案壓縮的品質。 預設值為 50。 *(人數)*(請注意相機的解析度有關的資訊是不可用)。
* **可** 選擇傳回值的格式。預設值是 FILE_URI。定義在 `navigator.camera.DestinationType` *(人數)*
Camera.DestinationType = {
DATA_URL : 0, // Return image as base64-encoded string
FILE_URI : 1, // Return image file URI
NATIVE_URI : 2 // Return image native URI (e.g., assets-library:// on iOS or content:// on Android)
};
* **時** 設置圖片的來源。預設值是觀景窗。定義在 `navigator.camera.PictureSourceType` *(人數)*
Camera.PictureSourceType = {
PHOTOLIBRARY : 0,
CAMERA : 1,
SAVEDPHOTOALBUM : 2
};
* **allowEdit** 允許簡單編輯前選擇圖像。*(布林)*
* **encodingType** 選擇返回的影像檔的編碼。預設值為 JPEG。定義在 `navigator.camera.EncodingType` *(人數)*
Camera.EncodingType = {
JPEG : 0, // Return JPEG encoded image
PNG : 1 // Return PNG encoded image
};
* **targetWidth** 向尺度圖像的圖元寬度。必須用**targetHeight**。縱橫比保持不變。*(人數)*
* **targetHeight** 以圖元為單位向尺度圖像的高度。必須用**targetWidth**。縱橫比保持不變。*(人數)*
* **媒體類型** 設置的媒體,從選擇類型。 時才起作用 `PictureSourceType``PHOTOLIBRARY``SAVEDPHOTOALBUM` 。 定義在 `nagivator.camera.MediaType` *(人數)*
Camera.MediaType = {
PICTURE: 0, // allow selection of still pictures only. 預設情況。 Will return format specified via DestinationType
VIDEO: 1, // allow selection of video only, WILL ALWAYS RETURN FILE_URI
ALLMEDIA : 2 // allow selection from all media types
};
* **correctOrientation** 旋轉圖像,該設備時捕獲的定向的正確。*(布林)*
* **saveToPhotoAlbum** 將圖像保存到相冊在設備上捕獲後。*(布林)*
* **popoverOptions** 只有 iOS 在 iPad 中指定氣泡框位置的選項。在中定義`CameraPopoverOptions`.
* **cameraDirection** 選擇相機以使用 (前面或後面-面向)。預設值是背。定義在 `navigator.camera.Direction` *(人數)*
Camera.Direction = {
BACK : 0, // Use the back-facing camera
FRONT : 1 // Use the front-facing camera
};
### 亞馬遜火 OS 怪癖
* 任何 `cameraDirection` 值回朝的照片中的結果。
* 忽略 `allowEdit` 參數。
* `Camera.PictureSourceType.PHOTOLIBRARY``Camera.PictureSourceType.SAVEDPHOTOALBUM` 都顯示相同的相冊。
### Android 的怪癖
* 任何 `cameraDirection` 值結果在背面的照片。
* 忽略 `allowEdit` 參數。
* `Camera.PictureSourceType.PHOTOLIBRARY``Camera.PictureSourceType.SAVEDPHOTOALBUM` 都顯示相同的寫真集。
### 黑莓 10 的怪癖
* 忽略 `quality` 參數。
* 忽略 `allowEdit` 參數。
* `Camera.MediaType`不受支援。
* 忽略 `correctOrientation` 參數。
* 忽略 `cameraDirection` 參數。
### 火狐瀏覽器作業系統的怪癖
* 忽略 `quality` 參數。
* `Camera.DestinationType`將被忽略並且等於 `1` (影像檔的 URI
* 忽略 `allowEdit` 參數。
* 忽略 `PictureSourceType` 參數 (使用者選擇它在對話方塊視窗中)
* 忽略`encodingType`
* 忽略了 `targetWidth``targetHeight`
* `Camera.MediaType`不受支援。
* 忽略 `correctOrientation` 參數。
* 忽略 `cameraDirection` 參數。
### iOS 的怪癖
* 設置 `quality` 低於 50避免在某些設備上的記憶體不足錯誤。
* 當使用 `destinationType.FILE_URI` ,照片都保存在應用程式的臨時目錄。應用程式結束時,將刪除該應用程式的臨時目錄中的內容。
### 泰怪癖
* 不支援的選項
* 總是返回一個檔的 URI
### Windows Phone 7 和 8 的怪癖
* 忽略 `allowEdit` 參數。
* 忽略 `correctOrientation` 參數。
* 忽略 `cameraDirection` 參數。
* 忽略 `saveToPhotoAlbum` 參數。 重要: 使用 wp7/8 科爾多瓦攝像頭 API 拍攝的所有圖像總是都複製到手機的相機膠捲。 根據使用者的設置,這可能也意味著圖像是自動上傳到他們另。 這有可能意味著的圖像,可以比你的應用程式的目的更多的觀眾。 如果此阻滯劑您的應用程式,您將需要實現 CameraCaptureTask 在 msdn 上記載: [HTTP://msdn.microsoft.com/en-us/library/windowsphone/develop/hh394006.aspx][3]你可能還評論或在[問題追蹤器][4]的向上投票的相關的問題
* 忽略了 `mediaType` 屬性的 `cameraOptions` 作為 Windows Phone SDK 並不提供從 PHOTOLIBRARY 中選擇視頻的方法。

## CameraError
onError 的回呼函數提供了一條錯誤訊息。
function(message) {
// Show a helpful message
}
### 參數
* **message** 消息提供的設備的本機代碼。*String*
## cameraSuccess
提供的圖像資料的 onSuccess 回呼函數。
function(imageData) {
// Do something with the image
}
### 參數
* **imageData** Base64 編碼進行編碼的圖像資料,*或*影像檔的 URI取決於 `cameraOptions` 效果。*String*
### 示例
// Show image
//
function cameraCallback(imageData) {
var image = document.getElementById('myImage');
image.src = "data:image/jpeg;base64," + imageData;
}
## CameraPopoverHandle
`navigator.camera.getPicture` 創建的氣泡框對話方塊的控制碼.
### 方法
* **setPosition** 設置氣泡框的位置。
### 支援的平臺
* iOS
### setPosition
設置氣泡框的位置。
**參數**
* `cameraPopoverOptions` `CameraPopoverOptions` ,指定新的位置
### 示例
var cameraPopoverHandle = navigator.camera.getPicture(onSuccess, onFail,
{ destinationType: Camera.DestinationType.FILE_URI,
sourceType: Camera.PictureSourceType.PHOTOLIBRARY,
popoverOptions: new CameraPopoverOptions(300, 300, 100, 100, Camera.PopoverArrowDirection.ARROW_ANY)
});
// Reposition the popover if the orientation changes.
window.onorientationchange = function() {
var cameraPopoverOptions = new CameraPopoverOptions(0, 0, 100, 100, Camera.PopoverArrowDirection.ARROW_ANY);
cameraPopoverHandle.setPosition(cameraPopoverOptions);
}
## CameraPopoverOptions
iOS 僅指定氣泡框的錨元素的位置和箭頭方向,從 iPad 庫或專輯選擇圖像時的參數。
{ x : 0,
y : 32,
width : 320,
height : 480,
arrowDir : Camera.PopoverArrowDirection.ARROW_ANY
};
### CameraPopoverOptions
* **x** x 螢幕元素到其錨定氣泡框上的圖元座標。*(人數)*
* **y** 螢幕元素到其錨定氣泡框上的 y 圖元座標。*(人數)*
* **width** 寬度以圖元為單位),到其錨定氣泡框上的螢幕元素。*(人數)*
* **height** 高度以圖元為單位),到其錨定氣泡框上的螢幕元素。*(人數)*
* **arrowDir** 氣泡框上的箭頭應指向的方向。定義在 `Camera.PopoverArrowDirection` *(人數)*
Camera.PopoverArrowDirection = {
ARROW_UP : 1, // matches iOS UIPopoverArrowDirection constants
ARROW_DOWN : 2,
ARROW_LEFT : 4,
ARROW_RIGHT : 8,
ARROW_ANY : 15
};
請注意氣泡框的大小可能會更改箭頭的方向和螢幕的方向進行調整。 請確保帳戶方向更改時指定錨元素位置。
## navigator.camera.cleanup
刪除中間從臨時存儲攝像機所拍攝的照片。
navigator.camera.cleanup( cameraSuccess, cameraError );
### 描述
刪除保留在臨時存儲在調用 `camera.getPicture` 後的中間的影像檔。 適用只有當 `Camera.sourceType` 的值等於 `Camera.PictureSourceType.CAMERA``Camera.destinationType` 等於 `Camera.DestinationType.FILE_URI`.
### 支援的平臺
* iOS
### 示例
navigator.camera.cleanup(onSuccess, onFail);
function onSuccess() {
console.log("Camera cleanup success.")
}
function onFail(message) {
alert('Failed because: ' + message);
}
