Display image from blob using javascript and websockets

Question

I\'m currently working on a WebSocket application that is displaying images send by a C++ server. I\'ve seen a couple of topics around there but I can\'t seem to get rid of

Answer 1

Thanks, it's working great!!

So I figure I'd share my final javascript code:

var socket = new WebSocket('ws://'+host+':'+port, protocol);
socket.binaryType = 'arraybuffer';

try {
    socket.onopen = function() {
        document.getElementById('status').style.backgroundColor = '#40ff40';
        document.getElementById('status').textContent = 'Connection opened';
    }

    socket.onmessage = function(msg) {
        var arrayBuffer = msg.data;
        var bytes = new Uint8Array(arrayBuffer);

        var image = document.getElementById('image');
        image.src = 'data:image/png;base64,'+encode(bytes);
    }

    socket.onclose = function(){
        document.getElementById('status').style.backgroundColor = '#ff4040';
        document.getElementById('status').textContent = 'Connection closed';
    }
} catch(exception) {
    alert('Error:'+exception);
}

don't really understand why the blob version is so tricky but this did the trick!
