J'ai utilisé une bibliothèque pratique appelée extracteur de métadonnées lors de la création d'un processus pour lire Exif sur Java / Android. Comme l'extracteur de métadonnées est en lecture seule, supprimez, ajoutez ou modifiez les informations Exif à l'aide d'une autre bibliothèque ou implémentez-la vous-même.
String path = "c:\image\img0001.jpg "; //Chemin du fichier
File jpegFile = new File(path);
//Obtenir des méta-informations
Metadata metadata = ImageMetadataReader.readMetadata(jpegFile);
//Affichage complet des informations Exif
for (Directory directory : metadata.getDirectories()) {
for (Tag tag : directory.getTags()) {
System.out.println(tag);
}
}
Cliquez ici pour afficher les valeurs individuellement.
