解释 JavaFX 中二维图形的平滑属性
smooth 属性指定是否使用抗锯齿提示。可以使用 javafx.scene.shape.Shape 类的 setSmooth() 方法将值设为该属性。
此方法接受一个布尔值,如果传递 true,则形状的边缘将被平滑化。
示例
import javafx.application.Application;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.scene.shape.Polygon;
import javafx.scene.shape.StrokeLineJoin;
import javafx.scene.text.Font;
import javafx.scene.text.FontPosture;
import javafx.scene.text.FontWeight;
import javafx.scene.text.Text;
import javafx.stage.Stage;
public class SmoothExample extends Application {
public void start(Stage stage) {
Font font = Font.font("verdana", FontWeight.BOLD, FontPosture.REGULAR, 12);
Text label2 = new Text("Smooth: true");
label2.setFont(font);
label2.setX(80.0);
label2.setY(250.0);
Polygon shape1 = new Polygon(100.0, 75.0, 50.0, 200.0, 200.0, 200.0);
shape1.setStroke(Color.BLUE);
shape1.setStrokeWidth(20);
shape1.setStrokeLineJoin(StrokeLineJoin.MITER);
shape1.setSmooth(true);
Text label3 = new Text("Smooth: false");
label3.setFont(font);
label3.setX(370.0);
label3.setY(250.0);
Polygon shape2 = new Polygon(450.0, 75.0, 350.0, 200.0, 500.0, 200.0);
shape2.setStroke(Color.BLUE);
shape2.setStrokeWidth(20.0);
shape2.setStrokeLineJoin(StrokeLineJoin.MITER);
shape2.setSmooth(false);
//Creating a Group object
Group root = new Group(label2, label3, shape1, shape2);
//Creating a scene object
Scene scene = new Scene(root, 595, 310);
//Setting title to the Stage
stage.setTitle("Smooth Example");
//Adding scene to the stage
stage.setScene(scene);
//Displaying the contents of the stage
stage.show();
}
public static void main(String args[]){
launch(args);
}
}输出
