使用Java程序读取JPG Tif等格式图片的exif信息
package com.util;
import java.io.File;
import java.util.Iterator;
import com.drew.imaging.ImageProcessingException;
import com.drew.metadata.Directory;
import com.drew.metadata.Metadata;
import com.drew.metadata.MetadataException;
import com.drew.metadata.exif.ExifDirectory;
import com.drew.metadata.exif.ExifReader;
public class ExifUtil {
public static void main(String[] args) {
try {
ExifReader er =new ExifReader(new File("填照片路径"));//也就用inputstream 或者二进制流
Metadata exif = er.extract();
Iterator itr = exif.getDirectoryIterator();
while (itr.hasNext()) {
Directory directory = (Directory) itr.next();
System.out.println(directory.getString(ExifDirectory.TAG_EXIF_VERSION));
System.out.println(directory.getString(ExifDirectory.TAG_MAKE));
System.out.println(directory.getString(ExifDirectory.TAG_MODEL));
System.out.println(directory.getString(ExifDirectory.TAG_FNUMBER));
System.out.println(directory.getString(ExifDirectory.TAG_EXPOSURE_TIME));
System.out.println(directory.getString(ExifDirectory.TAG_ISO_EQUIVALENT));
System.out.println(directory.getString(ExifDirectory.TAG_SOFTWARE));
System.out.println(directory.getDate(ExifDirectory.TAG_DATETIME_DIGITIZED));
System.out.println(directory.getDate(ExifDirectory.TAG_DATETIME_ORIGINAL));
System.out.println(directory.getString(ExifDirectory.TAG_ORIENTATION));
System.out.println(directory.getString(ExifDirectory.TAG_EXIF_IMAGE_WIDTH));
System.out.println(directory.getString(ExifDirectory.TAG_EXIF_IMAGE_HEIGHT));
System.out.println(directory.getString(ExifDirectory.TAG_X_RESOLUTION));
System.out.println(directory.getString(ExifDirectory.TAG_Y_RESOLUTION));
System.out.println(directory.getString(ExifDirectory.TAG_EXPOSURE_BIAS));
}
} catch (ImageProcessingException e) {
e.printStackTrace();
} catch (MetadataException e) {
e.printStackTrace();
}
}
}
下面给一个实体类，可以方便存储exif信息
