         * reason: The performance of 'URL.createObjectURL' is better than 'reader.readAsDataURL' ,

         * 'reader.readAsDataURL' will generate base64 code and auto GC.If we use 'URL.createObjectURL' here,
         * When the remote desktop is running long time and image chaning always,it will be out of memory.
