如何用java将图片裁剪成圆圈？

import java.awt.*;
import java.awt.geom.*;
import java.awt.image.*;
import java.io.*;
import javax.imageio.*;

public class ImageCrop {
    public static void main(String[] args) {
        try {
            // 读取原始图片
            BufferedImage originalImage = ImageIO.read(new File("original.jpg"));

            // 创建一个透明的 BufferedImage，用于绘制圆形图片
            BufferedImage circleImage = new BufferedImage(originalImage.getWidth(), originalImage.getHeight(), BufferedImage.TYPE_INT_ARGB);

            // 获取 Graphics2D 对象，用于绘制图形
            Graphics2D g2d = circleImage.createGraphics();

            // 设置抗锯齿
            g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);

            // 创建一个圆形剪切区域
            Ellipse2D.Double clip = new Ellipse2D.Double(0, 0, originalImage.getWidth(), originalImage.getHeight());

            // 将剪切区域应用于 Graphics2D 对象
            g2d.setClip(clip);

            // 绘制原始图片到圆形剪切区域
            g2d.drawImage(originalImage, 0, 0, null);

            // 释放资源
            g2d.dispose();

            // 保存圆形图片
            ImageIO.write(circleImage, "PNG", new File("circle.png"));

            System.out.println("图片裁剪完成！");
        } catch (IOException e) {
            e.printStackTrace();
        }
    }
}
