This method is provided to support TIFF tags that you define. If no such tag exists in the image, this method will return a null reference (Nothing in Visual Basic).
To read all the tags stored in a file, use ReadTags(String,Int32)
You can use TagsSupported to determine whether a certain file format supports tags.
