exif 디지털카메라로 찍은 jpeg 사진 meta정보 추출하기 - 2005년글

http://www.okjsp.net/seq/42447

위 사마귀는 몇 년전 여름에 찍은 사진이고 실험에 사용된 것입니다.

 

예전에 분명히 이 자료 찾다가 못 찾았는데 결국은 찾았네요.

 

암튼 열심히 부지런히 웹서핑해야됩니다. ㅋㅋㅋ

 

http://drewnoakes.com/code/exif/

 

위 사이트로 가서 metadata-extractor-2.2.2.jar - compiled classes 를 다운받도록 합니다.

 

그리고 http://drewnoakes.com/code/exif/sampleUsage.html 에서 sample 코드를 참고하도록 합니다.

 

import java.io.File;
import java.util.Iterator;
import com.drew.metadata.Tag;
import com.drew.metadata.Directory;
import com.drew.metadata.Metadata;
import com.drew.imaging.jpeg.JpegMetadataReader;
import com.drew.imaging.jpeg.JpegProcessingException;

public class DicaMetaData
{
 public static void main(String [] args) throws JpegProcessingException{

  File jpegFile = new File("DSCN1036.JPG");
  Metadata metadata = JpegMetadataReader.readMetadata(jpegFile);

  // iterate through metadata directories
  Iterator directories = metadata.getDirectoryIterator();
  while (directories.hasNext()) {
   Directory directory = (Directory)directories.next();
   // iterate through tags and print to System.out
   Iterator tags = directory.getTagIterator();
   while (tags.hasNext()) {
    Tag tag = (Tag)tags.next();
    // use Tag.toString()
    System.out.println(tag);
   }
  }
 }
    
}

 

실행하면
