Working with metadata in AVIF images Leave feedback

AVIF (AV1 Image File Format) stores images compressed with the AV1 codec in a HEIF container. Like other modern image formats, AVIF files can carry EXIF and XMP metadata. The AvifRootPackage class implements both the IExif and IXmp interfaces.

1. Load an AVIF image
2. Get the root metadata package
3. Read the XMP package with getXmpPackage and the EXIF package with getExifPackage. Both can be null if the image has no such metadata.

try (Metadata metadata = new Metadata(Constants.InputAvif)) {
    AvifRootPackage root = metadata.getRootPackageGeneric();

    if (root.getXmpPackage() != null && root.getXmpPackage().getSchemes().getXmpDynamicMedia() != null) {
        System.out.println(String.format("XmpDynamicMedia Artist: %s", root.getXmpPackage().getSchemes().getXmpDynamicMedia().getArtist()));
    }

    if (root.getExifPackage() != null) {
        System.out.println(String.format("ExifPackage Artist: %s", root.getExifPackage().getArtist()));
    }
}

For more details on reading and updating XMP metadata, please refer to the following guide: Working with XMP metadata.

Please find more code samples in the Working with EXIF metadata section.
