Java获取图片的尺寸

souven

用Java实现获取一张图片的尺寸，示例用下：

1. import java.awt.image.BufferedImage;
   
2. import java.io.File;
   
3. import java.io.IOException;
   
4. import javax.imageio.ImageIO;
   
5. 
   
6. public class img {
   
7. 
   
8.         /**
   
9.          * example of getting the information(width,height) of a image
   
10.          * @throws IOException
    
11.          */
    
12.         public static void main(String[] args) throws IOException {
    
13.                 String imgPath = "D:\\1.jpg"; //the path of the image file
    
14.                 BufferedImage bufferedImage = ImageIO.read(new File(imgPath));
    
15.                 int width = bufferedImage.getWidth();
    
16.                 int height = bufferedImage.getHeight();
    
17.                 //the variables width,height is what we want
    
18.         }
    
19. 
    
20. }

代码过于简单，此帖甚虚，欢迎拍砖。
