IccCurveTagType Class

Summary

Contains the curveType tag type data.

Syntax

C++

public class IccCurveTagType : IccTagTypeBase

  
Public Class IccCurveTagType  
   Inherits IccTagTypeBase

public ref class IccCurveTagType : public IccTagTypeBase

Remarks

The signature for this tag type is IccTagTypeBase.CurveTypeSignature.

Example

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

using Leadtools; 
using Leadtools.ColorConversion; 
 
public void IccCurveTagTypeExample() 
{ 
   // load an Icc Profile 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "EmptyIcc.icc"); 
   IccProfileExtended iccProfile = new IccProfileExtended(fileName); 
 
   // preparing curve data, it consists of domain and range values 
   // if we have 1 value, it should be in the u8Fixed8Number format, 
   // and if we have more than 1 value, their type should be uInt16Number (ushort), 
   // in this example we will use 1 value, look at the VB example for more 
   // than 1 value curve data example 
   // for more information about domain and range values refere to  
   // ICC.1:2004-10 specification page 39. 
   double myDoubleValue = 1.5; 
   ushort[] curveData = new ushort[1]; 
   curveData[0] = IccTools.FromDoubleToU8Fixed8Number(myDoubleValue); 
 
   // to read the value back from the curve data use the following function 
   myDoubleValue = IccTools.FromU8Fixed8NumberToDouble(curveData[0]); 
 
   // create the new iccCurveType 
   IccCurve iccCurve = new IccCurve(curveData); 
 
   // define the tag type 
   IccCurveTagType iccCurveTagType = new IccCurveTagType(iccCurve); 
 
   // add the new tag to the ICC Profile 
   iccProfile.AddTag(iccCurveTagType, IccTag.GrayTRCTag, IccTagTypeBase.CurveTypeSignature); 
 
   // generate the new profile id 
   iccProfile.GenerateProfileId(); 
 
   // update the icc array with the new changes 
   iccProfile.UpdateDataArray(); 
 
   // write the Icc Profile into a new file 
   string IccfileName = Path.Combine(LEAD_VARS.ImagesDir, "IccCurveTagTypeCS.icc"); 
   iccProfile.GenerateIccFile(IccfileName);
