java实现合并图片的方法示例

package com.test;import java.io.File;import java.awt.image.BufferedImage;import javax.imageio.ImageIO;public class ImageCombineTest {  public static void main(String args[]) {    try {      // 读取第一张图片      File fileOne = new File("/Users/coolcloud/Pictures/Art/lena-2.jpg");      BufferedImage ImageOne = ImageIO.read(fileOne);      int width = ImageOne.getWidth();      // 图片宽度      int height = ImageOne.getHeight();      // 图片高度      // 从图片中读取RGB      int[] ImageArrayOne = new int[width * height];      ImageArrayOne = ImageOne.getRGB(0, 0, width, height, ImageArrayOne,      0, width);      // 对第二张图片做相同的处理      File fileTwo = new File("/Users/coolcloud/Pictures/Art/lena-2.jpg");      BufferedImage ImageTwo = ImageIO.read(fileTwo);      int[] ImageArrayTwo = new int[width * height];      ImageArrayTwo = ImageTwo.getRGB(0, 0, width, height, ImageArrayTwo,      0, width);      // 生成新图片      // BufferedImage ImageNew = new BufferedImage(width * 2, height,      // BufferedImage.TYPE_INT_RGB);      BufferedImage ImageNew = new BufferedImage(width*2, height*2,      BufferedImage.TYPE_INT_RGB);      ImageNew.setRGB(0, 0, width, height, ImageArrayOne, 0, width);      // 设置左半部分的RGB      // ImageNew.setRGB(width, 0, width, height, ImageArrayTwo, 0, width);// 设置右半部分的RGB      // ImageNew.setRGB(0, height, width, ImageOne.getHeight()+ImageTwo.getHeight(), ImageArrayTwo, 0, width);// 设置右半部分的RGB      ImageNew.setRGB(0, height, width, height, ImageArrayTwo, 0, width);      // 设置右半部分的RGB      File outFile = new File("/Users/coolcloud/Pictures/generatepic.jpg");      ImageIO.write(ImageNew, "png", outFile);      // 写图片    }    catch (Exception e) {      e.printStackTrace();    }  }}
