How do I convert a byte array to an image in Node.js? I have tried the code below. It creates an image but when I open it, I get an error message

Error interpreting JPEG image file.

I have converted the byte array from bitmap in Android and sent it to a Node server.

var mkdirp = require('mkdirp');

var fs = require('fs');

var bitmap = new Buffer(bytearray,'base64');

mkdirp(__dirname + "/images/",function(er)
{

  if(er) console.log(er);

  fs.writeFileSync(__dirname + "/images/"+profile._id+".jpeg",bitmap);

});
