      this.compositeCtx = this.ctx;
      this.transparentCanvas = transparentCanvas.canvas;
      this.ctx = transparentCanvas.context;
      this.ctx.save();
      
      
      this.ctx.transform.apply(this.ctx, this.compositeCtx.mozCurrentTransform);
    }
    this.ctx.save();
    resetCtxToDefault(this.ctx);
