public class TIFFTagSet extends Object
A class representing a set of TIFF tags. Each tag in the set must have a unique number (this is a limitation of the TIFF specification itself).This class and its subclasses are responsible for mapping between raw tag numbers and
TIFFTagobjects, which contain additional information about each tag, such as the tag's name, legal data types, and mnemonic names for some or all of its data values.- Since:
