写的一个小玩具,用来把一张图分割成九宫图,满足发图就想发九张的强迫症

package pictureDivide;import java.awt.image.BufferedImage;import java.io.File;import java.io.IOException;import javax.imageio.ImageIO;public class NineZoneDiv{ public static void main(String[] args){ //imageIO或者fileIO能够读取图像 //BufferedImage创建一个实际的图像缓冲区,可以直接操作像素 //bufferedImage.getSbuImage返回由指定矩形区域定义的子图像。 //返回的 BufferedImage 与源图像共享相同的数据数组。 String scrImageFile = "poi.jpg"; String targetDir = "nineZornPoi"; BufferedImage img = null; BufferedImage scrImage = null; try { scrImage = ImageIO.read(new File(scrImageFile)); } catch (IOException e) { // TODO Auto-generated catch block e.PRintStackTrace(); } int scrHeight = scrImage.getHeight(); int divHeight = scrHeight / 3; int scrWidth = scrImage.getWidth(); int divWidth = scrWidth / 3; System.out.println("width" + scrWidth); System.out.println("height" + scrHeight); String fileName = null; for(int i = 0; i < 3; i++){ for(int j = 0; j < 3; j++){ img = scrImage.getSubimage(j * divWidth, i * divHeight, divWidth, divHeight); fileName = targetDir +"_" + i + "_" + j + ".jpg"; //文件名 File file = new File(fileName); try { ImageIO.write(img, "JPEG", file); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } System.out.println("save" + i + j); } } System.out.println("succes"); }}
