javafx直线类Line

Line

Line继承与Shape，而Shape继承与Node，对于Node的子类，都可以设置基本的监听器，鼠标事件和键盘事件，当然样式设置也是有的。

代码

public class JacobLine extends Application{
	public static void main(String[] args) {launch();}
    public void start(Stage primaryStage) throws Exception {
    	Pane pane = createPane();
        primaryStage.setScene(new Scene(pane));
        primaryStage.setWidth(900);
        primaryStage.setHeight(900);
        primaryStage.setTitle("Line ");
        primaryStage.show();
    }
	private Pane createPane() {
		Pane pane=new Pane();
		Line line = null;
		for(int radi=0;radi<360;radi+=1) {
			line=new Line();
			line.setStartX(400f);
			line.setStartY(0f);
			line.setEndX(400.0f);
			line.setEndY(800.0f);
			line.setRotate(radi/Math.PI*180);
			line.setLayoutX(100*Math.cos(radi));
			line.setLayoutY(100*Math.sin(radi));
			pane.getChildren().add(line);
		}
		for(int i=0;i<pane.getChildren().size();i+=1) {
			if(i%2==0) {
				((Line)(pane.getChildren().get(i))).setStroke(Color.color(i/360,0.5, 0.5));
			}else {
				((Line)(pane.getChildren().get(i))).setStroke(Color.color(1-i/360,0.5, 0.3));
			}
		}
		pane.setLayoutY(30);
		pane.setLayoutX(50);
		return pane;
	}

}

通过设置平移和旋转的角度可以的到许多有趣的图形

（默认顺时针旋转）

不旋转

//	line.setRotate(radi/Math.PI*180);
	line.setLayoutX(100*Math.cos(radi));
	line.setLayoutY(100*Math.sin(radi));

得到一个柱体

设置透明度

	line.setOpacity(0.5);

将颜色关掉，便于观察

我感觉在质数点出现奇异形状较高

	line.setRotate(radi);

	line.setRotate(180-radi);

	line.setRotate(radi*0.01);

	line.setRotate(radi*0.1);

	line.setRotate(radi*0.2);

	line.setRotate(radi*0.25);

	line.setRotate(radi*0.3);

	line.setRotate(radi*0.5);

	line.setRotate(radi);

	line.setRotate(2*radi);

	line.setRotate(radi*3);

	line.setRotate(radi*4);

		line.setRotate(radi*7);

	line.setRotate(radi*8);

	line.setRotate(radi*9);

	line.setRotate(radi*13);

	line.setRotate(radi*15);

	line.setRotate(radi*16);

	line.setRotate(radi*17);

	line.setRotate(radi*19);

	line.setRotate(radi*31);

	line.setRotate(radi*120);

	line.setRotate(radi*133);

	line.setRotate(radi*313);

（和上图一样，并不是截错了）

	line.setRotate(radi*317);
