这可以很容易地在Java中进行，

int width = 100; 
    int height = 30; 

    //BufferedImage image = ImageIO.read(new File("/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("/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); 
    }

是Graphics2D的使用上固醇？ – Beyka
