如何使用JavaFX实现Android scaleType="centerCrop"

我有我的图像视图：

ImageView myImage = new ImageView("https://example.com/image/my_image.png");

//maybe
//myImage.scaleType = "centerCrop";

感谢@TravisF的帖子，我实现了最后一个解决方案，使图像始终具有相同的高度、宽度和位置（中心）

double newMeasure = (userImage.getImage().getWidth() < userImage.getImage().getHeight()) ? userImage.getImage().getWidth() : userImage.getImage().getHeight();
double x = (userImage.getImage().getWidth() - newMeasure) / 2;
double y = (userImage.getImage().getHeight() - newMeasure) / 2;

Rectangle2D rect = new Rectangle2D(x, y, newMeasure, newMeasure);
userImage.setViewport(rect);
userImage.setFitWidth(150);
userImage.setFitHeight(150);
userImage.setSmooth(true);
