Our LDAP server returns the thumbnail in the following binary format. How can I save the stream as an image on the computer using NodeJS?

I tried the following solution, but the saved file thumbnail.jpeg cannot be opened as an image:

var fs = require('fs');

fs.writeFile('thumbnail.jpeg', {my binary stream}, 'binary',
  function(err){
    if (err) throw err;
    console.log('File saved.')     
  })

please see http://stackoverflow.com/questions/5294470/node-js-writing-image-to-local-server the answer by Drasill should get you there the fastest. – sakurashinken Aug 18 '15 at 22:25
looks like you've converted the binary data to utf8 string and saving it. Try saving the original buffer data. – hassansin Aug 19 '15 at 00:46
@hassansin Thanks! You are right. I got the the original buffer data and it works :-) – G Chen Aug 19 '15 at 17:23

@GChen can you post an update on what exactly you did ? I'm also stopped at this point. – Harshad Ranganathan Jan 08 '16 at 14:02
