Photoshop Scripting: How to convert psd image in base64 in jsx to send it on server

i working on photoshop plugin. want convert photoshop psd file in base64 can send on server. following code not running. gives evalscript error.

<pre>

var filepath = app.activedocument.path + '/' + name + '.png';

  //get file buffer
  var f= new file(filepath);
  f.open();
  f.encoding = 'binary';
  var buffer = f.read(f.length);
  f.close();

  //file buffer base64
  var base64 = base64encode(buffer);

  return base64;

</pre>

i guess base64encode() function not exists. don't see definition in code , photoshop script core bit old , think doesn't has built-in function that.

 

you google old school method base64 conversion. like: base64.js/base64.js @ master · davidchambers/base64.js · github  should modifications.

 

or if have html panel. can send data javascript panel, use native built-in chrome function conversion (.atob) , send data back.

 

for sending use html panel , make ajax request or something. or use "socket" class in jsx (tcp/ip connection)

 

or if have public ip or if want use in lan can use connection sdk.
