Can JavaScript load raw bytes to use in HTML 5 Canvas?

Question

Say I had a file like... http://my.website.com/myfile.raw and this file was just raw bytes, representing an intensity image. Is it possible to grab this data and read the bytes in JavaScript? And then using it with HTML 5 canvas (e.g., putImageData) to draw an image?

Or is there some other way to do this in the browser without Java or Flash?

Answer 2

maybe

function draw() {
    var ctx = document.getElementById('canvas').getContext('2d');
    var img = new Image();
    img.onload = function(){
      ctx.drawImage(img,0,0);
      imageData = ctx.getImageData(0, 0, image.width, image.height)
      //now you can do something with imageData...
    }
    img.src = 'http://my.website.com/myfile.raw';
  }
