'Declaration
 
Public Function New( _
   ByVal colors() As ColorReplaceCommandColor, _

public ColorReplaceCommand( 
   ColorReplaceCommandColor[] colors,
   int hue,
   int saturation,
   int brightness
)

function ColorReplaceCommand( 
   colors ,
   hue ,
   saturation ,
   brightness 
)

public:
ColorReplaceCommand( 
   array<ColorReplaceCommandColor^>^ colors,
   int hue,
   int saturation,
   int brightness
)

Parameters

colors: An array of ColorReplaceCommandColor classes that provides information about the replacement color used by this class.
hue: Angular amount to change the hue, in hundredths of degrees. Valid values range from -18000 to 18000. This value is divided internally by 100.
saturation: Amount to change saturation, in tenths of a percent. Valid values range from -1000 to 1000. This value is divided internally by 10. Negative values decrease the saturation of colors. Positive values increase the saturation. The saturation level is increased or decreased by a percentage of its present saturation level. For example, an increase of 20 of the current saturation level "L" will raise the new saturation level "L1" to a value L = 0.20 * L. Likewise, increasing the saturation level 100 doubles the saturation level (L1 = L + 1.0 * L). Decreasing the saturation level 100 will set the new saturation level to 0. The saturation is set to 1000 (maximum value) if the new value exceeds 1000).
brightness: Amount to change the brightness, in tenths of a percent. Valid values range from -1000 to 1000. This value is divided internally by 10. Positive values increase (or lighten) the brightness of the image. Negative values decrease (or darken) the brightness of the image.
