[Java] Java Read EXIF

Java 讀取數位相片EXIF檔的程式碼

package exif;


import com.drew.imaging.jpeg.JpegMetadataReader;
import com.drew.imaging.jpeg.JpegProcessingException;
import com.drew.metadata.Directory;
import com.drew.metadata.Metadata;
import com.drew.metadata.Tag;
import java.io.File;
import java.io.IOException;
import java.util.logging.Level;
import java.util.logging.Logger;

public class Exif {

    /**

     */
    public static void main(String[] args) {
        File jpegFile = new File("/Users/flowercatswets/Desktop/test/P1080033.JPG");  
    
    Metadata metadata = null;  
        try {
            metadata = JpegMetadataReader.readMetadata(jpegFile);
            print(metadata);
        } catch (JpegProcessingException ex) {
            Logger.getLogger(Exif.class.getName()).log(Level.SEVERE, null, ex);
        } catch (IOException ex) {
            Logger.getLogger(Exif.class.getName()).log(Level.SEVERE, null, ex);
        }
        
    }
    
     private static void print(Metadata metadata)
    {
        System.out.println("-------------------------------------");

      
        for (Directory directory : metadata.getDirectories()) {

          
            for (Tag tag : directory.getTags()) {
                System.out.println(tag);
                
               // String tagName= tag.getTagName();
                //String tagDes=tag.getDescription();
                
            }

            //
            // Each Directory may also contain error messages
            //
            if (directory.hasErrors()) {
                for (String error : directory.getErrors()) {
                    System.err.println("ERROR: " + error);
                }
            }
        }
    }
    
}

但是要先去拉一個專案的code下來

https://github.com/drewnoakes/metadata-extractor

Netbean滙不進這一個專案，所以我把裡面的Source資料夾下的程式碼COPY到

專案中，讓import可以正常，接下來找一張相片。

執行一下輸出結果
