send image from websocket server .NET to client (HTML5)

Question

I'm currently implementing websocket communication betweeb the server (VB .NET) and the client(web page)

I succeeded in sending text from server to the client and display the text using JavaScript and canvas,

Now I want to send an image from the server to be displayed in the HTML5 canvas,

The websocket server implementation I use is Fleck

any suggestion? I lack binary/bmp knowledge

From a quick look at the Fleck source, you can send binary data using

string imgFilePath = ...
socket.send(System.IO.File.ReadAllBytes(imgFilePath));

(where socket will be a member variable you store in the OnOpen delegate of the IWebSocketConnection passed to your server's Start method)

Note that not all browsers support reading binary frames yet. Recent versions of Chrome support it; I'm not sure if any others do yet.

I think it will work, do you know how to receive it at the client side(JavaScript)? I assume it's to convert the binary to image
