# org.apache.cordova.camera
Dieses Plugin stellt eine API für Aufnahmen und für die Auswahl der Bilder aus dem System-Image-Library.
cordova plugin add org.apache.cordova.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 eine base64-codierte übergeben `String` , oder als den URI für die Image-Datei. 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 standardmäßig, wenn `Camera.sourceType` gleich `Camera.PictureSourceType.CAMERA` . Sobald der Benutzer die Fotoschnäpper, die Kameraanwendung geschlossen wird und die Anwendung wird wiederhergestellt.
Wenn `Camera.sourceType` ist `Camera.PictureSourceType.PHOTOLIBRARY` oder `Camera.PictureSourceType.SAVEDPHOTOALBUM` , dann ein Dialog-Displays, die Benutzern ermöglicht, ein vorhandenes Bild auszuwählen. Die `camera.getPicture` Funktion gibt ein `CameraPopoverHandle` -Objekt, das verwendet werden kann, um den Bild-Auswahl-Dialog, zum Beispiel beim ändert sich der Orientierung des Geräts neu positionieren.
Der Rückgabewert wird gesendet, um die `cameraSuccess` Callback-Funktion in einem der folgenden Formate, je nach dem angegebenen `cameraOptions` :
* 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 auch wenn ein `quality` -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
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 und 8
* Windows 8
### 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 Macken
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.

### 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 eine `destinationType` der `Camera.DestinationType.FILE_URI` und eine `sourceType` von`Camera.PictureSourceType.PHOTOLIBRARY`.

});
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);
}

# org.apache.cordova.camera
Este plugin proporciona una API para tomar fotografías y por elegir imágenes de biblioteca de imágenes del sistema.
cordova plugin add org.apache.cordova.camera
## navigator.camera.getPicture
Toma una foto con la cámara, o recupera una foto de Galería de imágenes del dispositivo. La imagen se pasa a la devolución de llamada de éxito como un codificado en base64 `String` , o como el URI para el archivo de imagen. 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` :
* A `String` que contiene la imagen codificada en base64.
* A `String` que representa la ubicación del archivo de imagen de almacenamiento local (por defecto).
Puedes hacer lo que quieras con la imagen codificada o URI, por ejemplo:
* Utilidad de la imagen en un `<img>` etiqueta, 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 fuego OS
* Android
* BlackBerry 10
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 y 8
* Windows 8
### 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.
### 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() {
// do your thing here!
}, 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

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);
}
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 image = document.getElementById('myImage');
image.src = imageURI;
}

# org.apache.cordova.camera
Ce plugin fournit une API pour la prise de photos et de choisir des images de la bibliothèque d'images du système.
cordova plugin add org.apache.cordova.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 passée au callback "succès" comme une `String` encodée en base64 ou l'URI du fichier de l'image. La méthode elle-même renvoie un objet `CameraPopoverHandle` qui permet de repositionner la boite de dialogue de selection d'image.
navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );
### Description
La fonction `camera.getPicture` ouvre l'application 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 a pris la photo, l'application "camera" se ferme et l'application est restaurée.
Si `Camera.sourceType` est `Camera.PictureSourceType.PHOTOLIBRARY` ou `Camera.PictureSourceType.SAVEDPHOTOALBUM`, alors une boîte de dialogue s'affiche pour permettre aux utilisateurs de sélectionner une image existante. La fonction `camera.getPicture` retourne un objet `CameraPopoverHandle` 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 fonction callback `cameraSuccess`, dans l'un des formats suivants, selon spécifié par `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 encodée ou l'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. Les photos sélectionnées de la Galerie de l'appareil ne sont pas réduites avec une baisse de la qualité, même si un paramètre de `qualité` est spécifié. Pour éviter les problèmes de mémoire, définissez `Camera.destinationType` à `FILE_URI` plutôt que `DATA_URL`.
### Plates-formes prises en charge
* Amazon Fire OS
* Android
* BlackBerry 10
* Firefox OS
* iOS
* Paciarelli
* Windows Phone 7 et 8
* Windows 8
### 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.
### Spécificités 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.
### 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() {/ / votre code ici!}, 0) ;
### Spécificités Windows Phone 7
Invoquant l'application native caméra alors que l'appareil est connecté via Zune ne fonctionne pas et déclenche un rappel de l'erreur.
### Spécificités Tizen
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 = "data:image/jpeg;base64," + imageData;
}
function onFail(message) {
alert('Failed because: ' + 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('Failed because: ' + message);
}

# org.apache.cordova.camera
This plugin provides an API for taking pictures and for choosing images from
the system's image library.
cordova plugin add org.apache.cordova.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
- Firefox OS
- iOS
- Tizen
- Windows Phone 7 and 8
- Windows 8
### 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.
### 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. _(Number)_ (Note that information about the camera's resolution is unavailable.)
- __destinationType__: Choose the format of the return value. 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. 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. 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). Defined in `navigator.camera.Direction` _(Number)_
Camera.Direction = {
BACK : 0, // Use the back-facing camera
FRONT : 1 // Use the front-facing camera
};
### Amazon Fire OSQuirks
- 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.
- Ignores the `allowEdit` parameter.
- `Camera.PictureSourceType.PHOTOLIBRARY` and `Camera.PictureSourceType.SAVEDPHOTOALBUM` both display the same photo album.
### BlackBerry 10 Quirks
- Ignores the `quality` parameter.
- Ignores the `sourceType` 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. You may delete the contents of this directory using the `navigator.fileMgr` APIs if storage space is a concern.
### 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)

# org.apache.cordova.camera
Questo plugin fornisce un'API per scattare foto e per aver scelto immagini dalla libreria di immagini del sistema.
cordova plugin add org.apache.cordova.camera
## navigator.camera.getPicture
Prende una foto utilizzando la fotocamera, o recupera una foto dalla galleria di immagini del dispositivo. L'immagine viene passata al metodo di callback successo come una codifica base64 `String` , o come l'URI per il file di immagine. Il metodo stesso restituisce un `CameraPopoverHandle` che può essere utilizzato per riposizionare il Muffin di selezione file.
navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );
### Descrizione
il `camera.getPicture` funzione 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` , quindi un display finestra di dialogo che consente agli utenti di selezionare un'immagine esistente. La `camera.getPicture` la funzione restituisce un `CameraPopoverHandle` oggetto, che può essere utilizzato per riposizionare la finestra di selezione immagine, ad esempio, quando l'orientamento del dispositivo.
Il valore restituito viene inviato alla `cameraSuccess` funzione di callback, in uno dei seguenti formati, a seconda che l'oggetto specificato `cameraOptions` :
* 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 un `quality` è specificato il parametro. Per evitare problemi di memoria comune, impostare `Camera.destinationType` a `FILE_URI` piuttosto che`DATA_URL`.
### Piattaforme supportate
* Amazon fuoco OS
* Android
* BlackBerry 10
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 e 8
* Windows 8
### 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.
### Firefox OS stranezze
Fotocamera plugin è attualmente implementato mediante [Attività Web][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS stranezze
Compreso un JavaScript `alert()` in entrambi il callback funzioni possono 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() {/ / fai la tua cosa qui!}, 0);
### Windows Phone 7 capricci
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 un `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;
}

# org.apache.cordova.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。
cordova plugin add org.apache.cordova.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。 イメージは base64 エンコードとして成功時のコールバックに渡される `String` 、またはイメージ ファイルの URI。 メソッド自体を返します、 `CameraPopoverHandle` オブジェクト 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することができます。
navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );
### 説明
`camera.getPicture`関数はデバイスのデフォルトのカメラ アプリケーションの写真をスナップするユーザーことができますを開きます。 既定では、この現象が発生したときに `Camera.sourceType` に等しい `Camera.PictureSourceType.CAMERA` 。 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。
場合 `Camera.sourceType` は、 `Camera.PictureSourceType.PHOTOLIBRARY` または `Camera.PictureSourceType.SAVEDPHOTOALBUM` 、その後、ダイアログが表示されますユーザーを既存のイメージを選択することができます。 `camera.getPicture`関数を返す、 `CameraPopoverHandle` オブジェクトは、たとえば、イメージの選択ダイアログには、デバイスの向きが変更されたときの位置を変更するために使用することができます。
戻り値に送信されます、 `cameraSuccess` の指定によって、次の形式のいずれかのコールバック関数 `cameraOptions` :
* 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が下方の品質に縮小しない場合でも、 `quality` パラメーターを指定します。 一般的なメモリの問題を回避する設定 `Camera.destinationType``FILE_URI` よりもむしろ`DATA_URL`.

# org.apache.cordova.camera
Wtyczka dostarcza API do robienia zdjęć i wybór zdjęć z biblioteki obrazu systemu.
cordova plugin add org.apache.cordova.camera
## navigator.camera.getPicture
Pobiera zdjęcia za pomocą aparatu lub z galerii zdjęć w urządzeniu. Obraz jest przekazywany do funkcji zwrotnej success jako `String` kodowany za pomocą base64 lub jako URI do pliku. Sama metoda zwraca obiekt `CameraPopoverHandle`, który może służyć do zmiany położenia wyskakującego okna wyboru pliku.
navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );
### Opis
Funkcja `camera.getPicture` otwiera na urządzeniu domyślną aplikację aparatu, która pozwala użytkownikowi zrobić zdjęcie. To zachowanie występuje domyślnie, gdy `Camera.sourceType` jest równe `Camera.PictureSourceType.CAMERA`. Gdy użytkownik wykona zdjęcie, aplikacja aparatu zakończy działanie i nastąpi powrót do głównej aplikacji.
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 wysyłana do funkcji zwrotnej `cameraSuccess` w jednym z następujących formatów, w zależności od określonego parametru `cameraOptions`:
* Jako `String` zawierający obraz zakodowany przy użyciu base64.
* Jako `String` reprezentujący lokację pliku obrazu w lokalnym magazynie (domyślnie).
Z zakodowanym obrazem lub URI możesz zrobić co zechcesz, na przykład:
* Przedstawia obraz w tagu `<img>`, jak w przykładzie poniżej
* Zapisuje dane lokalnie (`LocalStorage`, [Lawnchair][1], etc.)
* Wysyła dane na zdalny serwer
[1]: http://brianleroux.github.com/lawnchair/
**Uwaga**: zdjęcie rozdzielczości na nowsze urządzenia jest bardzo dobry. Zdjęcia wybrane z galerii urządzenia nie są skalowane do niższej jakości, nawet jeśli określono parametr `quality`. Aby uniknąć typowych problemów z pamięcią lepiej ustawić`Camera.destinationType` na `FILE_URI` niż `DATA_URL`.
### Obsługiwane platformy
* Amazon ogień OS
* Android
* Jeżyna 10
* Firefox OS
* iOS
* Tizen
* Windows Phone 7 i 8
* Windows 8
### 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 takim scenariuszu obrazy mogą nie być wyświetlane po przywróceniu aktywności Cordovy.
### Android dziwactwach
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.
### Firefox OS dziwactwa
Aparat plugin jest obecnie implementowane za pomocą [Działania sieci Web][2].
[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS dziwactwa
Tym JavaScript `alert()` w jednej z wywołania zwrotnego funkcji może powodować problemy. Owinąć alert w `setTimeout()` umożliwia wybór obrazu iOS lub popover całkowicie zamknąć zanim wyświetli alert:
setTimeout(function() {
// do your thing here!
}, 0);
### Windows Phone 7 dziwactwa
Wywoływanie aparat native aplikacji, podczas gdy urządzenie jest podłączone przez Zune nie działa i powoduje błąd wywołania zwrotnego.
### Tizen dziwactwa
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. *(Liczba)* (Pamiętaj, że informacja o rozdzielczości aparatu jest niedostępna.)
* **destinationType**: Wybierz format zwracanej wartości. 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)
};

Camera.EncodingType = {
JPEG : 0, // Return JPEG encoded image
PNG : 1 // Return PNG encoded image
};
* **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, // umożliwia wybór tylko zdjęcia. DOMYŚLNIE. 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). Zdefiniowane w `navigator.camera.Direction` *(numer)*
Camera.Direction = {
BACK : 0, // Używa tylnej kamery
FRONT : 1 // Używa przedniej kamery
};
### Amazon ognia OSQuirks
* 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.
### Android dziwactwa
* Wszelkie `cameraDirection` wartość wyników w zdjęcie tyłu do kierunku jazdy.
* Ignoruje `allowEdit` parametr.
* `Camera.PictureSourceType.PHOTOLIBRARY`i `Camera.PictureSourceType.SAVEDPHOTOALBUM` wyświetlać ten sam album zdjęć.
### Jeżyna 10 dziwactwa
* Parametr `quality` jest ignorowany.
* Parametr `sourceType` jest ignorowany.
* Ignoruje `allowEdit` parametr.
* Nie jest wspierane `Camera.MediaType`.
* Parametr `correctOrientation` jest ignorowany.
* Parametr `cameraDirection` jest ignorowany.
### Firefox OS dziwactwa
* Ignoruje `quality` parametr.
* `Camera.DestinationType`jest ignorowane i jest równa `1` (plik obrazu URI)
* Ignoruje `allowEdit` parametr.
* Ignoruje `PictureSourceType` parametr (użytkownik wybiera go w oknie dialogowym)
* Ignoruje`encodingType`
* Ignoruje `targetWidth` i`targetHeight`
* `Camera.MediaType`nie jest obsługiwane.
* Ignoruje `correctOrientation` parametr.
* Ignoruje `cameraDirection` parametr.
### iOS dziwactwa
* Ustaw `quality` poniżej 50 aby uniknąć błędów pamięci na niektórych urządzeniach.
* Jeśli użyjesz `destinationType.FILE_URI` zdjęcia zostaną zapisane w katalogu tymczasowym aplikacji. Jeżeli masz problemy z miejscem, możesz usunąć zawartość tego katalogu używając API `navigator.fileMgr`.
### Osobliwości Tizen
* opcje nie są obsługiwane
* zawsze zwraca FILE URI
### Windows Phone 7 i 8 dziwactwa
* Ignoruje `allowEdit` parametr.
* Ignoruje `correctOrientation` parametr.
* Ignoruje `cameraDirection` parametr.
* Ignoruje `mediaType` Właściwość `cameraOptions` jako SDK Windows Phone nie umożliwiają wybór filmów z PHOTOLIBRARY.

# org.apache.cordova.camera
這個外掛程式提供了一個 API拍照從系統的圖像庫中選擇圖像。
cordova plugin add org.apache.cordova.camera
## navigator.camera.getPicture
需要使用的相機,一張照片或從設備的圖像庫檢索一張照片。 圖像作為 base64 編碼傳遞成功回檔到 `String` ,或作為影像檔的 URI。 該方法本身返回 `CameraPopoverHandle` 可以用於重新置放檔選擇彈出的物件。
navigator.camera.getPicture( cameraSuccess, cameraError, [ cameraOptions ] );
### 說明
`camera.getPicture`函數將打開該設備的預設攝像頭應用程式,使使用者能夠對齊圖片。 預設情況下,會發生此行為時 `Camera.sourceType` 等於 `Camera.PictureSourceType.CAMERA` 。 一旦使用者快照照片、 攝像頭應用程式關閉,並恢復該應用程式。
如果 `Camera.sourceType``Camera.PictureSourceType.PHOTOLIBRARY``Camera.PictureSourceType.SAVEDPHOTOALBUM` ,然後允許使用者選擇一個現有圖像對話方塊的顯示。 `camera.getPicture`函數返回 `CameraPopoverHandle` 物件,可用於設備方向更改時重新置放圖像選擇對話方塊,例如。
傳回值發送到 `cameraSuccess` 回呼函數,根據指定的以下格式之一 `cameraOptions`
* 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。
你可以做任何你想與編碼的圖像或 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** 在較新的設備上的照片解析度是相當好。 從設備的庫選擇了照片不到較低的品質,壓縮螢幕使即使 `quality` 指定參數。 為了避免常見的記憶體問題,設置 `Camera.destinationType``FILE_URI` 而不是`DATA_URL`.
### 支援的平臺
* 亞馬遜火 OS
* Android 系統
* 黑莓 10
* 火狐瀏覽器作業系統
* iOS
* Tizen
* Windows Phone 7 和 8
* Windows 8
### 亞馬遜火 OS 怪癖
亞馬遜火 OS 使用意向啟動捕獲圖像,在設備上的相機活動和與低記憶體手機,科爾多瓦活動可能被殺。 在此方案中,可能不會顯示圖像還原科爾多瓦活動時。
### Android 的怪癖
Android 使用意向啟動捕獲圖像,在設備上的相機活動和與低記憶體手機,科爾多瓦活動可能被殺。 在此方案中,可能不會顯示圖像還原科爾多瓦活動時。

[2]: https://hacks.mozilla.org/2013/01/introducing-web-activities/
### iOS 的怪癖
包括 JavaScript `alert()` 中任一回檔的函數可能會導致問題。 換行內的警報 `setTimeout()` ,允許 iOS 圖像選取器或彈出要完全關閉之前警報將顯示:
setTimeout(function() {/ / 做你的事!}0)
### Windows Phone 7 的怪癖
調用本機攝像頭應用程式,同時通過 Zune 連接設備不工作,並觸發錯誤回檔。
### Tizen 怪癖
Tizen 僅支援 `destinationType``Camera.DestinationType.FILE_URI``sourceType``Camera.PictureSourceType.PHOTOLIBRARY`.
### 示例
拍一張照片,並檢索它為 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
