Java横向、纵向合并图片代码

分享到:

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();
}
	}
}
