Add image rotation

[mrAceT]

Hello,

I've started using (and updating) imgViewer2

And it works great for my needs.

I would really like to add a button to rotate the image in increments of 90 degrees, but I can't get it to work..

I've found this little snippet of code, and I'm sure it would help me, but my experience in this area is limited. Is there anyone here that could help me out?

PS: if so, I'll promise to share my improvements :)

L.rotateImageLayer = function(url, bounds, options) {
            return new L.RotateImageLayer(url, bounds, options);
          };
// A quick extension to allow image layer rotation.
          L.rotateImageLayer = L.ImageOverlay.extend({
            options: {rotation: 90},
            _animateZoom: function(e){
              L.ImageOverlay.prototype._animateZoom.call(this, e);
              var img = this._image;
              img.style[L.DomUtil.TRANSFORM] += ' rotate(' + this.options.rotation + 'deg)';
            },
            _reset: function(){
              L.ImageOverlay.prototype._reset.call(this);
              var img = this._image;
              img.style[L.DomUtil.TRANSFORM] += ' rotate(' + this.options.rotation + 'deg)';
            }
          });
