中心裁剪图像JavaFX

如何使用JavaFX完成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post，我已经实现了最后的解决方案，使图像始终具有相同的高度，widht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);
