FunctionalLightCommand Constructor(Int32,LeadPoint,FunctionalLightCommandFlags)

Summary

Initializes a new FunctionalLightCommand class object with explicit parameters.

Syntax

WinRT C#

C++

public FunctionalLightCommand(  
   int redAmplitude, 
   Leadtools.LeadPoint origin, 
   Leadtools.Imageprocessing.Specialeffects.FunctionalLightCommandFlags flags 
)

Public Function New( _ 
   ByVal redAmplitude As Integer, _ 
   ByVal origin As Leadtools.LeadPoint, _ 
   ByVal flags As Leadtools.Imageprocessing.Specialeffects.FunctionalLightCommandFlags _ 
)

public FunctionalLightCommand(  
   int redAmplitude, 
   Leadtools.LeadPoint origin, 
   Leadtools.Imageprocessing.Specialeffects.FunctionalLightCommandFlags flags 
)

function FunctionalLightCommand(  
   redAmplitude , 
   origin , 
   flags  
)

public: 
FunctionalLightCommand(  
   int redAmplitude, 
   Leadtools.LeadPoint origin, 
   Leadtools.Imageprocessing.Specialeffects.FunctionalLightCommandFlags flags 
)

Parameters

redAmplitude
If the image is grayscale, this parameter represents the amplitude of the master channel. If the image is color and the FunctionalLightCommandFlags.Multiply or FunctionalLightCommandFlags.LinearQuadratic flags are set, this parameter represents the amplitude of each channel. If the image is color and the FunctionalLightCommandFlags.Addition flag is used, this represents the amplitude of the red channel. This value is an integer with a value greater than or equal to 0. This value will be multiplied with the results of the selected function (sine, cosine, user buffer , _). The results of the multiplications are then added to the pixel values. These functions as well as the real buffer values are from -1 to 1. Possible values for the redAmplitude parameter are from 0-100.

origin
Represents the coordinates of the origin, in pixels. This parameter is used if the FunctionalLightCommandFlags.Trigonometry flag and the FunctionalLightCommandFlags.Circles flags are set, or if the FunctionalLightCommandFlags.LinearQuadratic flag is set.

flags
Flags that indicate the to use. For a list of available flags, FunctionalLightCommandFlags

Example

Run the FunctionalLightCommand on an image.
