Flip Images using HTML5 Canvas
You can flip an Image using HTML5 like this:
// flip x axis ctx.scale(-1, 1); ctx.drawImage(img, x, y); // flip it back again ctx.scale(-1, 1);
You can flip along the y axis in the same way. I'm note sure how fast this transformation is, in practice so you might need to cache it if you are doing realtime graphics.
