IccChromaticityTagType Class

Summary

Contains the chromaticityType tag type data.

Syntax

C++/CLI

Python

public class IccChromaticityTagType : IccTagTypeBase

public ref class IccChromaticityTagType : public IccTagTypeBase

class IccChromaticityTagType(IccTagTypeBase):

Remarks

The signature for this tag type is IccTagTypeBase.ChromaticityTypeSignature.

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.
