我已经尝试过这个选择并且运行正常，但我的要求仅适用于一个盒子并选择完整的场景。

这是我在选择时遇到的错误。
答案 0 :(得分：0)
您确定要正确设置事件处理程序吗？如果您查看setOnMousePressed（here）的方法签名，您将看到您没有指定输入事件类型。
通常应该像这样添加事件处理程序：
img.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
System.out.println("X: " + event.getX() + " Y: " + event.getY());
}
});
答案 1 :(得分：0)
通过此
获取坐标 private int x,y,w,h;
public void getCordinates() {
img.setOnMousePressed(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
x = (int) event.getX();
y = (int) event.getY();
}
});
img.setOnMouseReleased(new EventHandler<MouseEvent>() {
@Override
public void handle(MouseEvent event) {
w = (int) (event.getX() - x);
h = (int) (event.getY() - y);
}
});
}
然后通过将此行添加到空格键操作侦听器
来获取裁剪后的图像 PixelReader reader = srcImage.getPixelReader();
WritableImage newImage = new WritableImage(reader, x, y, w, h);
此处srcImage是您要从中选择区域的图像，因此请将其替换为您在代码中加载的图像。而newImage是裁剪后的图像
