Java_图片转字符

把高达头像转换成字符[-V-]

调节双循环里y与x的增量改变字符输出的细节、高和长

 public class ImgToStr {
     public static void main(String args []){
         //图片路径
         ImgToStr.createAsciiPic("D:\\StrLogo\\GUTy6x2.png");
     }

     public static void createAsciiPic(final String path) {
         //final String base = "@#&$%*o!;.";// 字符串由复杂到简单
         final String base = "/lVXvi*!;.'";
         try {
             final BufferedImage image = ImageIO.read(new File(path));
             System.out.println("W:"+image.getWidth()+" H:"+image.getHeight());
             for (int y = 0; y < image.getHeight(); y += 6) {
                 for (int x = 0; x < image.getWidth(); x+= 2) {
                     final int pixel = image.getRGB(x, y);
                     final int r = (pixel & 0xff0000) >> 16, g = (pixel & 0xff00) >> 8, b = pixel & 0xff;
                     final float gray = 0.299f * r + 0.578f * g + 0.114f * b;
                     final int index = Math.round(gray * (base.length() + 1) / 255);
                     System.out.print(index >= base.length() ? " " : String.valueOf(base.charAt(index)));
                 }
                 System.out.println();
             }
         } catch (final IOException e) {
             e.printStackTrace();
         }
     }
 }
