Start the camera application and return information about captured image files.
navigator.device.capture.captureImage(
CaptureCB captureSuccess, CaptureErrorCB captureError, [CaptureImageOptions options]
);
Starts an asynchronous operation to capture images using the device's camera application. The operation allows users to capture more than one image in a single session.
The capture operation ends either when the user closes the camera application, or the maximum number of recordings specified by CaptureAudioOptions.limit is reached. If no limit value is specified, it defaults to one (1), and the capture operation terminates after the user captures a single image.
When the capture operation finishes, it invokes the CaptureCB callback with an array of MediaFile objects describing each captured image file. If the user terminates the operation before capturing an image, the CaptureErrorCB callback executes with a CaptureError object featuring a CaptureError.CAPTURE_NO_MEDIA_FILES error code.
Invoking the native camera application while your device is connected via Zune does not work, and the error callback executes.
// capture callback
var captureSuccess = function(mediaFiles) {
var i, path, len;
for (i = 0, len = mediaFiles.length; i < len; i += 1) {
path = mediaFiles[i].fullPath;
// do something interesting with the file
}
};
// capture error callback
var captureError = function(error) {
navigator.notification.alert('Error code: ' + error.code, null, 'Capture Error');
};
// start image capture
navigator.device.capture.captureImage(captureSuccess, captureError, {limit:2});
