Java 獲取圖片屬性、獲取圖片EXIF屬性操作方法[metadata-extractor]

JSON 2019-07-27 18:49:02 17920

本站之前開發(fā)了圖片的一系列操作和查看工具，包括屬性查看，圖片轉(zhuǎn)換等等，依賴了別人的一些API，目前需要改成自己的API。

來查看這些上圖的圖片文件對應(yīng)的屬性：

依賴Jar包，metadata-extractor

github下載鏈接：https://github.com/drewnoakes/metadata-extractor/releases/tag/2.12.0

Maven 引入：

<dependency>
  <groupId>com.drewnoakes</groupId>
  <artifactId>metadata-extractor</artifactId>
  <version>2.12.0</version>
</dependency>

Gradle Groovy DSL

implementation 'com.drewnoakes:metadata-extractor:2.12.0'

Gradle Kotlin DSL

compile("com.drewnoakes:metadata-extractor:2.12.0")

其他查看這：https://search.maven.org/artifact/com.drewnoakes/metadata-extractor/2.12.0/jar

圖片屬性查看代碼

//獲取該圖片文件
        File file = new File("/Users/zhoubocheng/Downloads/IMG_2294.JPG");

        Metadata metadata = JpegMetadataReader.readMetadata(file);
        //輸出所有附加屬性數(shù)據(jù)
        for (Directory directory : metadata.getDirectories()) {
            System.out.println("屬性組：" + directory.getName());
            for (Tag tag : directory.getTags()) {
               String kv =  String.format("%s = %s",tag.getTagName(),tag.getDescription());
                System.out.println(kv);
            }
        }

查看圖片EXIF信息

注意需要手機或者相機等直接拍照的圖片，剪切圖，PS圖等等部分信息是缺失的。

//獲取EXIF信息，用直接相機或者手機拍出來的圖片來做獲取，剪切圖或者操作過裁剪大部分信息是讀取不到的
        System.out.println("++++++++++++++++++ EXIF ++++++++++++++++++++");

        ExifIFD0Directory exif = metadata.getFirstDirectoryOfType(ExifIFD0Directory.class);
        if(null != exif){
            //循環(huán)輸出
            exif.getTags().forEach(System.out::println);

            if(exif.containsTag(ExifIFD0Directory.TAG_MAKE)){
                System.out.println("Make:" + exif.getDescription(ExifIFD0Directory.TAG_MAKE));
            }
        }


        System.out.println("ExifSubIFDDirectory：");
        Directory exifSub = metadata.getFirstDirectoryOfType(ExifSubIFDDirectory.class);
        if(null != exifSub){
            //循環(huán)輸出
            exifSub.getTags().forEach(System.out::println);
        }

        System.out.println("ExifInteropDirectory：");
        Directory exifInterop = metadata.getFirstDirectoryOfType(ExifInteropDirectory.class);
        if(null != exifInterop){
            //循環(huán)輸出
            exifInterop.getTags().forEach(System.out::println);
        }

        System.out.println("ExifThumbnailDirectory：");
        Directory exifThumbnail = metadata.getFirstDirectoryOfType(ExifThumbnailDirectory.class);
        if(null != exifThumbnail){
            //循環(huán)輸出
            exifThumbnail.getTags().forEach(System.out::println);
        }
