思路:
将原图,竖向划分为10个等份,前两个等份作为1个参考图,后8份作为1张样本图,所以总共需要分割9张图出来(第一张占两份),然后将第一张参考图和后面8张样本图合并成8个样本结果即可。
实现
新建普通java 项目,Java单类实现代码,复制到java项目中,用idea编辑器 主方法运行。(引入的Class 都是JDK中自有的)
import javax.imageio.ImageIO; import java.awt.image.BufferedImage; import java.io.File; import java.io.IOException; public class ImageUtil { public static BufferedImage cutIO(int x, int y, int width, int height, BufferedImage img) { int[] imgRgb = new int[width * height]; System.out.println(x+" "+y+" "+width+" "+height); img.getRGB(x, y, width, height, imgRgb, 0, width); BufferedImage newImage = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB); newImage.setRGB(0, 0, width, height, imgRgb, 0, width); return newImage; } public static void cut(int x, int y, int width, int height, BufferedImage img, Integer num) { BufferedImage newImage = cutIO(x,y,width,height,img); newImage.setRGB(0, 0, width, height, new int[width * height], 0, width); try { ImageIO.write(newImage, "PNG", new File("C:\\Users\\tarzan\\Desktop\\image\\"+num+".png")); } catch (IOException e) { e.printStackTrace(); } } public static void exec(String IMG) throws IOException { BufferedImage image = ImageIO.read(new File(IMG)); int w=image.getWidth(); int d=w/10; int h=image.getHeight(); BufferedImage first = cutIO(0,0,d*2,h,image);; for (int i = 1; i < 9; i++) { BufferedImage img= cutIO(d*(i+1),0,d,h,image); mergeImage(first,img,"C:\\Users\\tarzan\\Desktop\\image\\0_"+(i)+".png"); } } public static void mergeImage(String imgPath1,String imgPath2,String margeImgPath){ try { BufferedImage bi_1 = ImageIO.read(new File(imgPath1)); BufferedImage bi_2 = ImageIO.read(new File(imgPath2)); mergeImage(bi_1,bi_2,margeImgPath); } catch (IOException e) { e.printStackTrace(); } } public static void mergeImage(BufferedImage bi_1,BufferedImage bi_2,String margeImgPath){ try{ //假设图片1 和图片2 高度相同,左右合成 //new 一个新的图像 int w_1 = bi_1.getWidth(); int w_2 = bi_2.getWidth(); int h= bi_1.getHeight(); int w= w_1 + w_2; BufferedImage bi=new BufferedImage(w,h,BufferedImage.TYPE_4BYTE_ABGR); //像素一个一个复制过来 for(int y=0; y<h; y++){ for(int x=0;x<w_1;x++){ bi.setRGB(x,y,bi_1.getRGB(x,y)); } } for(int y=0;y<h;y++){ for(int x=0;x<w_2;x++){ bi.setRGB(w_1+x,y,bi_2.getRGB(x,y)); } } //输出文件 ImageIO.write(bi,"png",new File(margeImgPath)); }catch(IOException ex){ ex.printStackTrace(); } } public static void main(String[] args) throws IOException { exec("C:\\Users\\tarzan\\Desktop\\image\\test.png"); // mergeImage("C:\\Users\\tarzan\\Desktop\\image\\1.png","C:\\Users\\tarzan\\Desktop\\image\\2.png","C:\\Users\\tarzan\\Desktop\\image\\1_2.png"); } } |
