Java横向、纵向合并图片代码

进行图片对比时候想把两张有差异的图片放到一起。

将纵向合并的自己调整了下，源码如下：

import java.io.File;  import java.awt.image.BufferedImage;  import javax.imageio.ImageIO;    public class TestPic {   public static void main(String[] args) {    xPic();   }      public static void xPic(){//横向处理图片    try {     /* 1 读取第一张图片*/      File fileOne = new File("E:\\1.png");     BufferedImage imageFirst = ImageIO.read(fileOne);     int width = imageFirst.getWidth();// 图片宽度     int height = imageFirst.getHeight();// 图片高度     int[] imageArrayFirst = new int[width * height];// 从图片中读取RGB     imageArrayFirst = imageFirst.getRGB(0, 0, width, height, imageArrayFirst, 0, width);       /* 1 对第二张图片做相同的处理 */     File fileTwo = new File("E:\\2.png");     BufferedImage imageSecond = ImageIO.read(fileTwo);     int[] imageArraySecond = new int[width * height];     imageArraySecond = imageSecond.getRGB(0, 0, width, height, imageArraySecond, 0, width);          // 生成新图片      BufferedImage imageResult = new BufferedImage(width * 2 , height,BufferedImage.TYPE_INT_RGB);     imageResult.setRGB(0, 0, width, height, imageArrayFirst, 0, width);// 设置左半部分的RGB     imageResult.setRGB(width, 0, width, height, imageArraySecond, 0, width);// 设置右半部分的RGB     File outFile = new File("D:\\out.jpg");     ImageIO.write(imageResult, "jpg", outFile);// 写图片    } catch (Exception e) {     e.printStackTrace();    }   }      public static void yPic(){//纵向处理图片    try {     /* 1 读取第一张图片*/      File fileOne = new File("D:\\1.GIF");     BufferedImage imageFirst = ImageIO.read(fileOne);     int width = imageFirst.getWidth();// 图片宽度     int height = imageFirst.getHeight();// 图片高度     int[] imageArrayFirst = new int[width * height];// 从图片中读取RGB     imageArrayFirst = imageFirst.getRGB(0, 0, width, height, imageArrayFirst, 0, width);       /* 1 对第二张图片做相同的处理 */     File fileTwo = new File("D:\\1.GIF");     BufferedImage imageSecond = ImageIO.read(fileTwo);     int[] imageArraySecond = new int[width * height];     imageArraySecond = imageSecond.getRGB(0, 0, width, height, imageArraySecond, 0, width);          // 生成新图片      BufferedImage imageResult = new BufferedImage(width, height * 2,BufferedImage.TYPE_INT_RGB);     imageResult.setRGB(0, 0, width, height, imageArrayFirst, 0, width);// 设置左半部分的RGB     imageResult.setRGB(0, height, width, height, imageArraySecond, 0, width);// 设置右半部分的RGB     File outFile = new File("D:\\out.jpg");     ImageIO.write(imageResult, "jpg", outFile);// 写图片    } catch (Exception e) {     e.printStackTrace();    }   }    }
