使用照相机盖拍摄的图像的未压缩尺寸

Question

我要掌握我的服务器图像，从设备的相机拍摄的图像，但事实的重量很大，质量非常好，质量非常好。我想知道是否有某种参数要宣布质量或至少文件的重量较低。

Camera.getPicture().then(function(imageURI) {
  $scope.imagen = imageURI;
  $scope.lastPhoto = imageURI;
  $scope.mostrar_form = true;
  $scope.mostrar_boton_view = false;
  google.maps.event.addDomListener(window, 'load', initialize);  
  initialize();
  document.getElementById('buton_refresh').click(); 
  $( "#buton_refresh" ).trigger( "click" );
}, function() {
  $scope.mostrar_boton_view = true;
  $ionicHistory.goBack();
}, {
  quality: 50,
  destinationType: Camera.DestinationType.FILE_URI,
  allowEdit: true,
  encodingType: Camera.EncodingType.JPEG,
  popoverOptions: CameraPopoverOptions,
  saveToPhotoAlbum: true,
  correctOrientation: true
})

功能上传图像：

$scope.publicarView = function(){
var server = URL_BASE+'addView/'+sessionService.get("user_id")+"/"+$scope.data.content+"/null/"+$scope.latitud+"/"+$scope.longitud+"/"+1;
var trustAllHosts = true;
var ftOptions = new FileUploadOptions();
ftOptions.fileKey = 'file';
ftOptions.fileName = $scope.imagen.substr($scope.imagen.lastIndexOf('/') + 1);
ftOptions.mimeType = 'image/jpeg';
ftOptions.httpMethod = 'POST';
console.log(ftOptions);
$cordovaFileTransfer.upload(encodeURI(server), $scope.imagen, ftOptions, trustAllHosts)
.then(function(result) {
  console.log(result)
}, function(err) {
  // Error
  console.log(err);
}, function (progress) {
  });
}

Cordova相机插件可以与以下参数一起使用：

var options = {
    quality: 50,
    destinationType: Camera.DestinationType.NATIVE_URL,
    sourceType: Camera.PictureSourceType.CAMERA,
    allowEdit: false,
    encodingType: Camera.EncodingType.JPEG,
    targetWidth: 700,
    targetHeight: 700,
    popoverOptions: CameraPopoverOptions,
    saveToPhotoAlbum: false,
    correctOrientation: true
};

以下参数对大小有影响：

quality: 50,
targetWidth: 700,
targetHeight: 700,

请参阅此处的官方文档：https://github.com/apache/cordova-plugin-camera

为了示例，我的代码拍照看起来像;

var options = {
        quality: 50,
        destinationType: Camera.DestinationType.NATIVE_URL,
        sourceType: Camera.PictureSourceType.CAMERA,
        allowEdit: false,
        encodingType: Camera.EncodingType.JPEG,
        targetWidth: 700,
        targetHeight: 700,
        popoverOptions: CameraPopoverOptions,
        saveToPhotoAlbum: false,
        correctOrientation: true
    };
    $cordovaCamera.getPicture(options).then(function(imageData) {
        d.resolve( { "img" : imageData });
    }, function(err) {
        d.reject(err);
    });
