反应konva放大和缩小鼠标指针位置上的鼠标滚动不正常

Question

我正在尝试使用react konva在一个omage上绘制矩形 我想在鼠标指针位置和鼠标滚轮事件放大/缩小图像时绘制一个矩形，但是问题是矩形是根据图像的位置绘制的，而不是舞台的，请帮助我解决这个问题

请参考我用于放大和缩小图像的代码

zoom=()=>{
    var oldScale = this.refs.layer.attrs.scaleX;
            mousePointTo = {
                x: this.props.x / oldScale - this.refs.layer.attrs.x / oldScale,
                y: this.props.y/ oldScale - this.refs.layer.attrs.y / oldScale,
            };  
           newScale = this.props.variation > 0 ? oldScale * this.props.scaleBy : oldScale / this.props.scaleBy; 
            newPos = {
                x: -(mousePointTo.x - this.props.x / newScale) * newScale,
                y: -(mousePointTo.y - this.props.y / newScale) * newScale
            }; 

            this.setState({newposx:newPos.x,newposy:newPos.y,newScale:newScale})
    }
