ASCII Art Java example
摘要: 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.

ASCIIArtService.java

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);

What is -1677216?
The color code, in this case all colors "-1677216" are replaced with empty " ". This is the idea to generate the ASCII art graphic. Try load an image, and print out the rgb color, you will noticed that different color has different code.
