getAscent()


Determines the font ascent of the Font described by this FontMetrics object. The font ascent is the distance from the font's baseline to the top of most alphanumeric characters. Some characters in the Font might extend above the font ascent line.

Syntax:
public int getAscent()


Example:

import java.awt.Color;
import java.awt.Font;
import java.awt.FontMetrics;
import java.awt.Graphics;
/*  w  w w  .jav a2s. c o m*/
import javax.swing.JFrame;
import javax.swing.JPanel;

public class Main extends JPanel {

  public void paint(Graphics g) {
    int fontSize = 20;
    g.setFont(new Font("TimesRoman", Font.PLAIN, fontSize));        
    FontMetrics fm = g.getFontMetrics();

    int baseline = fm.getMaxAscent() +  (h - (fm.getAscent() + fm.getMaxDecent()))/2;
  
    int ascent  = fm.getMaxAscent();
    int descent = fm.getMaxDecent();
    int fontHeight = fm.getMaxAscent() + fm.getMaxDecent();
  }

  public static void main(String[] args) {
    JFrame frame = new JFrame();
    frame.getContentPane().add(new Main());

    frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    frame.setSize(200,200);
    frame.setVisible(true);
  }
}
