GammaCorrectCommand Constructor(Int32)
See Also  Example



gamma
Integer that represents the gamma value. It can be any number greater than 0.
Because this is an unsigned integer (Integer with values greater than 0), it is 100 times the actual gamma value. For example, use 235 to set a gamma value of 2.35.
Initializes a new GammaCorrectCommand class object with explicit parameters.

Syntax

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

Parameters

gamma
Integer that represents the gamma value. It can be any number greater than 0.
Because this is an unsigned integer (Integer with values greater than 0), it is 100 times the actual gamma value. For example, use 235 to set a gamma value of 2.35.

Example

Run the GammaCorrectCommand on an image and apply gamma correction.

   ' Prepare the command
   'Set a gamma value of 2.5.
   Dim command As GammaCorrectCommand = New GammaCorrectCommand(250)
