Java reads EXIF information (size, shooting date, Mark) of the picture

1.Metadata-extractor is an open source project for processing image EXIF information, the latest code and:https://github.com/drewnoakes/metadata-extractor

2. The code for this demo project (contains the required jar package): Http://files.cnblogs.com/files/haha12/readPic.rar

The main code is as follows:

 Packagecom.test;ImportJava.io.File;Importjava.io.IOException;ImportJava.util.Iterator;ImportCom.drew.imaging.jpeg.JpegMetadataReader;Importcom.drew.imaging.jpeg.JpegProcessingException;Importcom.drew.metadata.Directory;ImportCom.drew.metadata.Metadata;ImportCom.drew.metadata.Tag; Public classReadpic {/*** Import tags, use metadata-extractor * *@paramargs*/     Public Static voidMain (string[] args) {readpic (); }    /*** Processing a single picture * *@returnvoid * @date 2015-7-25 pm 7:30:47*/    Private Static voidReadpic () {File jpegfile=NewFile ("D:\\002.jpg");        Metadata Metadata; Try{metadata=Jpegmetadatareader.readmetadata (Jpegfile); Iterator<Directory> it =metadata.getdirectories (). iterator ();  while(It.hasnext ()) {Directory exif=It.next (); Iterator<Tag> tags =exif.gettags (). iterator ();  while(Tags.hasnext ()) {tag tag=(TAG) tags.next ();                SYSTEM.OUT.PRINTLN (tag); }            }        } Catch(jpegprocessingexception e) {e.printstacktrace (); } Catch(IOException e) {e.printstacktrace (); }    }}

The console prints the following information:
