public GammaCorrectCommand( 
   int gamma
)

'Declaration
 
Public Function New( _
   ByVal gamma As Integer _
)

'Usage
 
Dim gamma As Integer
 
Dim instance As New GammaCorrectCommand(gamma)

public GammaCorrectCommand( 
   int gamma
)

- (id)initWithGamma:(unsigned int)gamma;

public GammaCorrectCommand(int gamma)

function GammaCorrectCommand( 
   gamma 
)

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.
