Java AffineTransform getTranslateY()

PreviousNext

Java AffineTransform getTranslateY() Returns the Y coordinate of the translation element (m12) of the 3x3 affine transformation matrix.

Syntax

The method getTranslateY() from AffineTransform is declared as: 

public double getTranslateY()

Return

The method getTranslateY() returns a double value that is the Y coordinate of the translation element of the affine transformation matrix.

import java.awt.Container;
import java.awt.Graphics;
import java.awt.Graphics2D;
import java.awt.Shape;
import java.awt.geom.AffineTransform;
import java.awt.geom.Rectangle2D;

import javax.swing.JComponent;
import javax.swing.JFrame;

public class Main {
    public static void main(String[] args) {
        JFrame jf = new JFrame("Demo");
        Container cp = jf.getContentPane();
        MyCanvas tl = new MyCanvas();
        cp.add(tl);/* w w  w   .   d  e m o    2 s .    co   m */
        jf.setSize(300, 200);
        jf.setVisible(true);
    }
}

class MyCanvas extends JComponent {

    public void paint(Graphics g) {
        Shape shape = new Rectangle2D.Float(100, 50, 80, 80);

        Graphics2D g2 = (Graphics2D) g;

        AffineTransform at = new AffineTransform();
        at.setToQuadrantRotation(2, 0.5, 0.5);

        System.out.println(at.getTranslateY());

        g2.setTransform(at);
        g2.draw(shape);

    }
}
