IccXyzNumber Structure

Summary

Contains three fixed signed quantities used to encode CIEXYZ tristimulus values.

Syntax

C++/CLI

Python

public struct IccXyzNumber

public value class IccXyzNumber : public System.ValueType

class IccXyzNumber:

Remarks

All Xyz numbers (other than those specifying luminance) shall be linearly scaled such that Y is specified over the range of 0 to 1.0.

Example

using Leadtools; 
using Leadtools.ColorConversion; 
 
 
public void IccXyzTagTypeExample() 
{ 
   // load an Icc Profile 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "ReadFromImageCS.icc"); 
   IccProfileExtended iccProfile = new IccProfileExtended(fileName); 
 
   // define the array of XYZ numbers 
   IccXyzNumber[] data = new IccXyzNumber[1]; 
   data[0] = new IccXyzNumber( 
      IccTools.FromDoubleTo2bFixed2bNumber(1.0), 
      IccTools.FromDoubleTo2bFixed2bNumber(2.0), 
      IccTools.FromDoubleTo2bFixed2bNumber(3.0)); 
 
   // define the tag type 
   IccXyzTagType xyzTagType = new IccXyzTagType(data); 
 
   // add the new tag to the ICC Profile 
   iccProfile.AddTag(xyzTagType, IccTag.RedMatrixColumnTag, IccTagTypeBase.XyzTypeSignature); 
 
   // 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, "IccXyzTagTypeCS.icc"); 
   iccProfile.GenerateIccFile(IccfileName); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
