What is text origin in JavaFX?
In addition to the local coordinate system for positioning its nodes, JavaFX provides an additional coordinate system for the text node.
The textOrigin property specifies the origin of the coordinates of the text node in the parent coordinate system. You can set values to this property using the setTextOrigin() method. This method accepts one of the constants of the enum named VPos. This enum contains 4 constants namely: BASELINE, BOTTOM, CENTER and, TOP.
Example
import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.InputStream;
import java.util.Scanner;
import javafx.application.Application;
import javafx.geometry.VPos;
import javafx.scene.Group;
import javafx.scene.Scene;
import javafx.scene.paint.Color;
import javafx.stage.Stage;
import javafx.scene.text.Text;
public class TextOriginExample extends Application {
public void start(Stage stage) throws FileNotFoundException {
//Reading the contents of a text file.
InputStream inputStream = new FileInputStream("D:\sample_text.txt");
Scanner sc = new Scanner(inputStream);
StringBuffer sb = new StringBuffer();
while(sc.hasNext()) {
sb.append(" "+sc.nextLine()+"\n");
}
//Creating a text object
Text text = new Text(10.0, 25.0, sb.toString());
//Wrapping the text
text.setWrappingWidth(565);
//Setting the vertical positioning
text.setTextOrigin(VPos.TOP);
//Setting the stage
Group root = new Group(text);
Scene scene = new Scene(root, 595, 150, Color.BEIGE);
stage.setTitle("Text Origin (TOP)");
stage.setScene(scene);
stage.show();
}
public static void main(String args[]){
launch(args);
}
}sample.txt

Tutorials Point originated from the idea that there exists a class of readers who respond better to online content and prefer to learn new skills at their own pace from the comforts of their drawing rooms. The journey commenced with a single tutorial on HTML in 2006 and elated by the response it generated, we worked our way to adding fresh tutorials to our repository which now proudly flaunts a wealth of tutorials and allied articles on topics ranging from programming languages to web designing to academics and much more.
Output
In the same way, if you change the alignment value you will get the outputs accordingly as −
