如何在Java中获得缩放Shape的新高度

I am scalling a shape for a specific point as follows :

我按照以下方式为特定点绘制形状:

                AffineTransform t = shape.getAffineTransform();

                AffineTransform translatAffine =AffineTransform.getTranslateInstance(-cx, -cy);
                AffineTransform scaleAffine= AffineTransform.getScaleInstance(sx,sy);
                scaleAffine.concatenate(translatAffine); 
                translatAffine = scaleAffine;

                scaleAffine =AffineTransform.getTranslateInstance(cx, cy);
                scaleAffine.concatenate(translatAffine);
                translatAffine = scaleAffine;                   

                scaleAffine= new AffineTransform(t);
                translatAffine.concatenate(scaleAffine); 
                shape.setAffineTransform(translatAffine);

When I try to get the new height with shape.getHeight(), I get the initial height

当我尝试使用shape.getHeight()获取新高度时,我得到初始高度

I found a work a round by getting the affineTransform and calculating the new height. I added the follwing line to the code above

通过获取affineTransform并计算新的高度,我找到了一个工作。我在上面的代码中添加了以下行

System.out.println("The new height :"+ shape.getHeight() *  shape.getAffineTransform().getScaleX());
