IccResponseCurveSet16TagType Class

Summary

Contains the responseCurveSet1Type tag type data.

Syntax

C++

public class IccResponseCurveSet16TagType : IccTagTypeBase

  
Public Class IccResponseCurveSet16TagType  
   Inherits Leadtools.Colorconversion.IccTagTypeBase

public ref class IccResponseCurveSet16TagType : public Leadtools.Colorconversion.IccTagTypeBase

Remarks

The signature for this tag type is IccTagTypeBase.ResponseCurveSet16TypeSignature.
The purpose of this tag type is to provide a mechanism to relate physical colorant amounts with the normalized device codes produced by lut8Type, lut16Type, lutAToBType or lutBToAType tags so that corrections can be made for variation in the device without having to produce a new profile.

Example

This example method can be used in creating an "responseCurveSet16Type" mentioned in the ICC.1:2004-10 specification.
