How can I make the text edges in the images smooth? [closed]

How can I make the text edges in the images smooth?

Here's the image:

If you're thinking of anti aliasing, you can typecast Graphics to Graphics2D then use g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);. You can do this after you draw the lines.

The above solution from Kevin Hikaru Evans should works, maybe you missed something.

Graphics2D g2=(Graphics2D)g.create();
g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING,RenderingHints.VALUE_ANTIALIAS_ON);
g2.drawString("SCQSCQSCQ",x,y);

Try this (quickly, crudely) adapted example..

import java.awt.*;
import java.awt.image.BufferedImage;
import java.awt.font.*;
import java.awt.geom.*;
import javax.swing.*;
import javax.imageio.ImageIO;
import java.io.File;

class PictureText {

    public static BufferedImage getImage(Area textOutline) {
        Rectangle bounds = textOutline.getBounds();
        System.out.println(bounds);
        int width = (2*(int)bounds.getX())+(int)bounds.getWidth();
        int height = (2*(int)bounds.getY())+(int)bounds.getHeight();
        BufferedImage bi = new BufferedImage(
            width,
            height,
            BufferedImage.TYPE_INT_ARGB);

        Color outline = new Color(0,0,0,255);

        Graphics2D g = bi.createGraphics();
        g.setRenderingHint(
            RenderingHints.KEY_ANTIALIASING,
            RenderingHints.VALUE_ANTIALIAS_ON);

        g.setStroke(new BasicStroke(1.5f));
        g.setColor(outline);
        g.draw(textOutline);

        showImage(bi);

        return bi;
    }

    public static void showImage(Image image) {
        JLabel textLabel = new JLabel(
            new ImageIcon(image));
        textLabel.setBackground(Color.WHITE);
        textLabel.setOpaque(true);

        JPanel gui = new JPanel(new GridLayout(0,1,5,5));
        gui.add(textLabel);

        JOptionPane.showMessageDialog(null,gui);
    }

    public static void main(String[] args) throws Exception {

        AffineTransform shrinkTransform2 =
            AffineTransform.getScaleInstance(.5,.5);

        final BufferedImage originalImage = new BufferedImage(

        g0.setPaint(gp);

        int width = originalImage.getWidth();
        int height = originalImage.getHeight();

        final BufferedImage textImage = new BufferedImage(

        Graphics2D g = textImage.createGraphics();

        FontRenderContext frc = g.getFontRenderContext();

        Font font1 = new Font(
            //"Wide Latin"
            //"Pythagoras"
            "Denmark"
            ,0,48);
        GlyphVector gv1 = font1.createGlyphVector(
            frc, "The quick brown fox..");
        Shape shape1 = gv1.getOutline(0,0);
        int y = (int)shape1.getBounds().getHeight()+2;
        Shape shapea = gv1.getOutline(6,y);
        Area area1 = new Area(shapea);
        Area area2nd = area1.createTransformedArea(shrinkTransform2);
        Area area4th = area1.createTransformedArea(shrinkTransform4);

        ImageIO.write(getImage(area1),"png",new File("text-image.png"));
    }
