public ChangeIntensityCommand(int brightness)

function ChangeIntensityCommand( 
   brightness 
)

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.
