Java: Read Exif Metadata Using metadata-extractor

In this post, I will show you the code snippet for extracting jpeg image exif metadata using metadata-extractor.

Code

package com.dukesoftware.image;

import com.drew.imaging.ImageMetadataReader;
import com.drew.imaging.ImageProcessingException;
import com.drew.metadata.Directory;
import com.drew.metadata.Metadata;
import com.drew.metadata.Tag;
import java.io.File;
import java.io.IOException;

public class MetaDataExtractor {

    public static void main(String[] args) throws IOException {
        printMetaData(new File("c:/temp/metadata_eample.jpg"));
    }

    private static void printMetaData(File file) throws IOException {
        try {
            Metadata drewmetadata = ImageMetadataReader.readMetadata(file);
            for (Directory directory : drewmetadata.getDirectories()) {
                System.out.println("==="+directory.getClass().getName()+"===");
                for (Tag tag : directory.getTags()) {
                    System.out.println(tag.getTagName()+ ": " + tag.getDescription());
                }
                System.out.println();
            }
        } catch (ImageProcessingException ipx) {
            
        }
    }

}
