cordova - Phone gap File type from DATA_URL -

how can file properties size, type data_url. using following code.

 function getimage() {      // retrieve image file location specified source      navigator.camera.getpicture(uploadphoto, null, {          quality: 50,          destinationtype: navigator.camera.destinationtype.data_url,          savetophotoalbum: true,          sourcetype: 2      });  }   function uploadphoto(data) {      // here want file type/ size  } 

is there way this?

i'm afraid can't directly, because picture returned base64 string. however, possible type , size.

type: can define type when setting options making picture cordova plugin. options set encodingtype. can set to:

camera.encodingtype = { jpeg : 0,               // return jpeg encoded image png : 1                 // return png encoded image };         

size: can calculated simple method this:

        var imagebytecount = function (imagestring) {         return encodeuri(imagestring)               .split(/%(?:u[0-9a-f]{2})?[0-9a-f]{2}|./).length -1;     } 

however, impossible other information of image. can return image file_uri or native_uri , load file file api of cordova. can more information file way.
