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; 
 
using Leadtools.Codecs; 
 
public string outputIccProfile = Path.Combine(LEAD_VARS.ImagesDir, "ColorConversion", "GetIccProfileTag", "IccXyzTagType.icc"); 
 
public void IccXyzTagTypeExample() 
{ 
   // load an ICC profile 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "ColorConversion", "InputProfile.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 
   iccProfile.GenerateIccFile(outputIccProfile); 
}
