How can I rotate the camera to portrait? #7

Hi, How can I rotate the camera to portrait for FaceDetection? Is it rotate the imageData?

        imageData.update = function() {
            var _imageDataCtx = imageDataCanvas.getContext("2d");
            _imageDataCtx.setTransform(1.0, 0, 0, 1, resolution.width, 0); // mirrored
            _imageDataCtx.rotate(90*Math.PI/180);

            _imageDataCtx.drawImage(webcamVideo, 0, 0, resolution.height, resolution.width);
        };

It seems not working perfectly.
