使用Java合并图片

在做自动化测试的时候,有时候需要对屏幕进行截图,还需要图片进行合并,合并的代码如下:

package com.jingshou.image;

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

public class ImageTest {
	public static String path = "pic\\";	

	public static void main(String[] args) throws IOException {
		File file1 = new File(path, "1.jpg");
		File file2 = new File(path, "2.jpg");
		mergeImage(file1, file2);
	}
	public static void mergeImage(File file1, File file2) throws IOException {		
		BufferedImage image1 = ImageIO.read(file1);
		BufferedImage image2 = ImageIO.read(file2);

		BufferedImage combined = new BufferedImage(image1.getWidth() * 2, image1.getHeight(), BufferedImage.TYPE_INT_RGB);

		// paint both images, preserving the alpha channels
		Graphics g = combined.getGraphics();
		g.drawImage(image1, 0, 0, null);
		g.drawImage(image2, image1.getWidth(), 0, null);
		
		// Save as new image
		ImageIO.write(combined, "JPG", new File(path, "3.jpg"));
	}

}

 不管是不是尺寸相同,都可以合并,只是尺寸相同的图片合并出来效果好一点

有什么办法可以找出合并的图片的位置吗？一张大图片，一张小图片，合并后再找出小图片的位置。
