Blue Property

Summary

Gets the color leveling information for the Blue channel when the Type property is set to AutoColorLevelCommandType.Level.

Syntax

Objective-C

C++/CLI

Java

Python

public ColorLevelCommandData Blue { get; }

@property (nonatomic, strong, readonly) LTColorLevelCommandData *blue;

public ColorLevelCommandData getBlue();

public: 
property ColorLevelCommandData^ Blue { 
   ColorLevelCommandData^ get(); 
}

Blue # get  (AutoColorLevelCommand)

Property Value

The color leveling information for the Blue channel. If AutoColorLevelCommandFlags.NoProcess is not set in Flag property, you can set the value of this property as null. If AutoColorLevelCommandFlags.NoProcess is set in Flag property, then this property cannot be null.

Remarks

If Flag property is set to either AutoColorLevelCommandType.Contrast or AutoColorLevelCommandType.Intensity, then the value of this property is unchanged. The AutoColorLevelCommand command updates the value of this property.
