IccViewCondition Structure

Summary

Contains viewing conditions data assumed for the media for which the profile is defined.

Syntax

C++/CLI

Python

public struct IccViewCondition

public value class IccViewCondition : public System.ValueType

class IccViewCondition:

Remarks

The viewing condition described in this tag is the actual viewing condition assumed for the media for which the profile is defined, specified in CIE 'absolute' units. Note that the luminanceTag must be the same as the Y value given in this tag.

Example

using Leadtools; 
using Leadtools.ColorConversion; 
 
 
public void IccViewingConditionsTagTypeExample() 
{ 
   // load an Icc Profile 
   string fileName = Path.Combine(LEAD_VARS.ImagesDir, "ReadFromImageCS.icc"); 
   IccProfileExtended iccProfile = new IccProfileExtended(fileName); 
 
   // define the absolute illuminant values 
   IccXyzNumber absIlluminant = new IccXyzNumber( 
      IccTools.FromDoubleTo2bFixed2bNumber(1.0), 
      IccTools.FromDoubleTo2bFixed2bNumber(2.0), 
      IccTools.FromDoubleTo2bFixed2bNumber(3.0)); 
 
   // define the absolute surround values 
   IccXyzNumber absSurround = new IccXyzNumber( 
      IccTools.FromDoubleTo2bFixed2bNumber(4.0), 
      IccTools.FromDoubleTo2bFixed2bNumber(5.0), 
      IccTools.FromDoubleTo2bFixed2bNumber(6.0)); 
 
   // create the IccViewCondition class 
   IccViewCondition viewCond = new IccViewCondition(absIlluminant, absSurround, IccStandardIlluminantType.IccIlluminantD50); 
 
   // define the tag type 
   IccViewingConditionsTagType viewCondTagType = new IccViewingConditionsTagType(viewCond); 
 
   // add the new tag to the ICC Profile 
   iccProfile.AddTag(viewCondTagType, IccTag.ViewingConditionsTag, IccTagTypeBase.ViewingConditionsTypeSignature); 
 
   // 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, "IccViewingConditionsTagTypeCS.icc"); 
   iccProfile.GenerateIccFile(IccfileName); 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\LEADTOOLS22\Resources\Images"; 
}
