How to add custom metadata to TIFF image

This code sample demonstrates how to add a custom tag to an EXIF package

Java


try (Metadata metadata = new Metadata("input.tiff")) {
    IExif root = (IExif) metadata.getRootPackage();

    //  Set the EXIF package if it's missing
    if (root.getExifPackage() == null) {
        root.setExifPackage(new ExifPackage());
    }

    //  Add a known property
    root.getExifPackage().set(new TiffAsciiTag(TiffTagID.Artist, "Artist's name"));

    //  Add a fully custom property (which is not described in the EXIF specification)
    //  Please note that the chosen ID may intersect with the IDs used by some third party tools
    root.getExifPackage().set(new TiffAsciiTag(TiffTagID.getByRawValue(65523), "Hidden data"));

    metadata.save("output.tiff");
}
