How to change angle for tiltshift effect?

[9itish]

I tried to change angle of tiltshift but could not. This was the code

 Caman.Filter.register("tiltShift", function(opts) {
 var defaults, gradient;

defaults = {
center: {
  x: this.dimensions.width / 2,
  y: this.dimensions.height / 2
},
angle: 45,
focusWidth: 200,
startRadius: 3,
radiusFactor: 1.5,
steps: 3
};
opts = Util.extend(defaults, opts);
opts.angle *= Math.PI / 180;
gradient = getLinearGradientMap(this.dimensions.width, this.dimensions.height, opts.center.x,  opts.center.y, opts.angle, opts.focusWidth, true);
return this.processPlugin("compoundBlur", [gradient, opts.startRadius, opts.radiusFactor, opts.steps]);
 });

I passed this.tiltShift(600,400,300,200,0,200,true).render(); but none of the defaults changes. What is the correct way to pass parameters.

The parameters are passed as an object. See the defaults object in the plugin for everything you can change.

this.tiltShift({angle: 95, startRadius: 200});
