Inheritance diagram for gdcm::Tag:
Detailed Description
Class to represent a DICOM Data Element (Attribute) Tag (Group, Element). Basically an uint32_t which can also be expressed as two uint16_t (group and element).
- Note:
- DATA ELEMENT TAG: A unique identifier for a Data Element composed of an ordered pair of numbers (a Group Number followed by an Element Number). GROUP NUMBER: The first number in the ordered pair of numbers that makes up a Data Element Tag. ELEMENT NUMBER: The second number in the ordered pair of numbers that makes up a Data Element Tag.
