IccChromaticityTagType Class

Summary
Contains the chromaticityType tag type data.
Syntax
C#
VB
C++
public class IccChromaticityTagType : IccTagTypeBase 
  
Public Class IccChromaticityTagType  
   Inherits IccTagTypeBase 
public ref class IccChromaticityTagType : public IccTagTypeBase  
Remarks
Example

This example method can be used in creating an "chromaticityType" mentioned in the ICC.1:2004-10 specification. This method fills an IccChromaticity type with the colorant encoding ITU-R BT.709.
