打印控制台字符图像

public static void main(String[] args) {
    BufferedImage image = new BufferedImage(200, 50, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g = image.createGraphics();
    g.setFont(new Font("楷体", Font.BOLD, 30));
    g.drawString("天气真好", 2, image.getHeight() - 20);
    int[] p = image.getRGB(0, 0,
            image.getWidth(),
            image.getHeight(),
            new int[image.getWidth() * image.getHeight()],
            0, image.getWidth());
    char[] cs = {'这', '是', '字', '符'};
    int ics = 0;

    for (int i = 0; i < image.getHeight(); i++) {
        for (int j = 0; j < image.getWidth(); j++) {
            int off = i * image.getWidth() + j;
            if (p[off] != 0) {
                System.out.print(cs[ics]);
                ics = (ics + 1) % 4;
            } else {
                System.out.print("\u3000");
            }
            if (j == image.getWidth() - 1) {
                System.out.println();
            }
        }
    }
}
