Setup

var i = 0,
        canvas, image = new Image(),
        toDataUrl = new Image(),
        drawCanvas = document.getElementById('canvas'),
        drawCtx = drawCanvas.getContext('2d'),
        i, size = 32;
    rx = 250, ry = 250, a = 10, t = Math.PI / 64, image.src = "http://c.dryicons.com/images/icon_sets/coquette_part_9_icons_set/png/32x32/speedometer.png";
    
    canvas = document.createElement('canvas'), canvas.width = size;
    canvas.height = size;
    ctx = canvas.getContext('2d');
    ctx.arc(size / 2, size / 2, size, 0, Math.PI * 2, true);
    ctx.globalAlpha = '0.2';
    ctx.fillStyle = "red";
    ctx.fill();
    
    toDataUrl.src = canvas.toDataURL("image/png");
