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(); } } } |
