像Whatsapp一样存储图像

Question

我尝试从相机拍摄照片并将拍摄的照片复制到新目录并使用新名称。我正确地创建了我的目录，但是当将图像从相机文件夹复制到新文件夹时，它警告我该错误：ENCODING_ERR

这是我的代码：

             Image: any;
            takePicture() {
           var options = {

          quality: 100,
  destinationType: this.camera.DestinationType.DATA_URL,
  encodingType: this.camera.EncodingType.JPEG,
  mediaType: this.camera.MediaType.PICTURE,
  saveToPhotoAlbum: true,


};


  // Get the data of an image
  this.camera.getPicture(options).then((imageData) => {
    // imageData is either a base64 encoded string or a file URI
    // If it's base64 (DATA_URL):
    this.Image= "data:image/jpeg;base64," + imageData;
    this.currentName = this.Image.replace(/^.*[\\\/]/, '');
     this.correctPath = this.Image.substr(0, this.Image.lastIndexOf('/') + 
       1);

   }, (err) => {
    // Handle error
     });

  }
