ChangeIntensityCommand Constructor(Int32)
See Also  Example



brightness
Amount to change the intensity. The intensity ranges from -1000 to 1000. A positive value increases (or lightens) the brightness of the image. A negative values decreases (or darkens) the brightness of the image.
Initializes a new ChangeIntensityCommand class object with explicit parameters.

Syntax

Visual Basic (Declaration) 
Public Function New( _
   ByVal brightness As Integer _
)
Visual Basic (Usage)Copy Code
Dim brightness As Integer
 
Dim instance As ChangeIntensityCommand(brightness)
C# 
public ChangeIntensityCommand( 
   int brightness
)
C++/CLI 
public:
ChangeIntensityCommand( 
   int brightness
)

Parameters

brightness
Amount to change the intensity. The intensity ranges from -1000 to 1000. A positive value increases (or lightens) the brightness of the image. A negative values decreases (or darkens) the brightness of the image.

Example

Run the ChangeIntensityCommand on an image and increase its intensity.
