IMAGINGJAVA-1121 Tiff XmpData and ExifData is not removed completely

Please use the following code to remove all Xmp and Exif metadata except Date Taken.:

 public void test_IMAGINGJAVA_1121()

{

    String dir = "D:\\1121\\";

    String fileName = dir + "TIF_1Page_LZW_Compression.tif";

    String outputFile = dir + "TIF_1Page_LZW_Compression_DeletedOptionalMetadata.tiff";

    TiffImage image = (TiffImage)Image.load(fileName);

    try

    {

        List<Integer> optionalTagsToRemove = new ArrayList<Integer>();

        Collections.addAll(optionalTagsToRemove,

            TiffTags.ImageDescription,

            TiffTags.Artist,

            TiffTags.DateTime,

            TiffTags.Software,

            TiffTags.Copyright,

            34377,       // Collection of Photoshop 'Image Resource Blocks'.

            33723        // IPTC (International Press Telecommunications Council) metadata.

        );

        removeExifAndXmpData(image, optionalTagsToRemove);

        setCreationDateTime(image, new Date());

        image.save(outputFile);

    }

    finally

    {

        image.close();

    }

}

}

/**
