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 Leadtools.ImageProcessing.Color.ChangeIntensityCommand class object with explicit parameters. Supported in Silverlight, Windows Phone 7

Syntax
