ASCII Art Java example

A funny Java example to create an ASCII art graphic. The concept is simple, get the image’s rgb color in “integer mode”, later, replace the color’s integer with ascii text.

P.S This example is credited for this post

package com.mkyong.service;
import java.awt.*;
import java.awt.image.BufferedImage;
import java.io.IOException;
public class ASCIIArtService {
    public static void main(String[] args) throws IOException {
        int width = 100;
        int height = 30;
        //BufferedImage image = ImageIO.read(new File("/Users/mkyong/Desktop/logo.jpg"));
        BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_RGB);
        Graphics g = image.getGraphics();
        g.setFont(new Font("SansSerif", Font.BOLD, 24));
        Graphics2D graphics = (Graphics2D) g;
        graphics.setRenderingHint(RenderingHints.KEY_TEXT_ANTIALIASING,
                RenderingHints.VALUE_TEXT_ANTIALIAS_ON);
        graphics.drawString("JAVA", 10, 20);
        //save this image
        //ImageIO.write(image, "png", new File("/users/mkyong/ascii-art.png"));
        for (int y = 0; y < height; y++) {
            StringBuilder sb = new StringBuilder();
            for (int x = 0; x < width; x++) {
                sb.append(image.getRGB(x, y) == -16777216 ? " " : "$");
            if (sb.toString().trim().isEmpty()) {
                continue;
            System.out.println(sb);

Output
