Rotating image using gestures after flipping is not working in winjs

Question

I first flipped an image and then rotated the image using gestures but the image is rotating in the opposite direction.

This is the code i used to flip the image

tempob.style.transform = m.scale(-1, 1, 1);// Horizontal flip
tempob.style.transform = m.scale(1, -1, 1);// vertical flip

Image rotates properly when not flipped while using gesture.

This is the code i used for manipulating gestures

 elt.style.transform = m.translate(e.offsetX, e.offsetY).
                        translate(e.translationX, e.translationY).
                        rotate(e.rotation * 180 / Math.PI).
                        scale(e.scale).
                        translate(-e.offsetX, -e.offsetY);

his code works properly according to the gestures when image is not flipped.

Thanks in advance
