How to Add Custom Metadata to a TIFF Image

This example demonstrates how to insert a custom tag into an EXIF package.

C#


    using (Metadata metadata = new Metadata("input.tiff"))
    {
        IExif root = metadata.GetRootPackage() as IExif;
        if (root != null)
        {
            //  Assign the EXIF package if it is missing.
            if (root.ExifPackage == null)
            {
                root.ExifPackage = new ExifPackage();
            }

            //  Insert a recognized property.
            root.ExifPackage.Set(new TiffAsciiTag(TiffTagID.Artist, "test artist"));

            //  Include a fully custom property that is not part of the EXIF specification.
            //  Be aware that the chosen ID may conflict with IDs used by some third-party tools.
            root.ExifPackage.Set(new TiffAsciiTag((TiffTagID)65523, "custom"));

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