Question

是否有Java库可以将文本写入图像,与PHP的GD库相同.

Answer 1

请尝试以下代码

import java.awt.Color;
import java.awt.Font;
import java.awt.Graphics;
import java.awt.image.BufferedImage;
import java.io.File;
import java.io.IOException;
import javax.imageio.ImageIO;

public class Testing {
    public static void main(String arg[]) throws IOException {
        String key = "Sample";
        BufferedImage bufferedImage = new BufferedImage(170, 30,
                BufferedImage.TYPE_INT_RGB);
        Graphics graphics = bufferedImage.getGraphics();
        graphics.setColor(Color.LIGHT_GRAY);
        graphics.fillRect(0, 0, 200, 50);
        graphics.setColor(Color.BLACK);
        graphics.setFont(new Font("Arial Black", Font.BOLD, 20));
        graphics.drawString(key, 10, 25);
        ImageIO.write(bufferedImage, "jpg", new File(
                "C:/Users/admin/desktop/image.jpg"));
        System.out.println("Image Created");
    }
}

当然.首先加载图像,可能使用的方法ImageIO.然后,使用Graphics表示图像本身的对象,调用该drawString方法.
