Summary

Initializes a new VignetteCommand with explicit parameters.

Syntax
C#
VB
C++
  
Public Function New( _ 
   ByVal origin As LeadPoint, _ 
   ByVal fading As Integer, _ 
   ByVal fadingRate As Integer, _ 
   ByVal width As Integer, _ 
   ByVal vignetteColor As RasterColor, _ 
   ByVal flags As VignetteCommandFlags _ 
) 
public: 
VignetteCommand(  
   LeadPoint origin, 
   int fading, 
   int fadingRate, 
   int width, 
   RasterColor vignetteColor, 
   VignetteCommandFlags flags 
) 

Parameters

origin
Center point for all vignette objects (circle, ellipse, rectangle, and square).

fading
Represents the percent of feathering in towards or outward from the vignette object. Negative values mean that the feathering will start outside the boundaries of the object and increase toward the object. Positive values mean that the feathering will start on the boundaries of the object and increase away from the object. Possible values range from -100 to 100.

fadingRate
Represents the value that indicates the fading rate. This value is used to controlling the fading process. It will be divided by 100 internally. The valid range is from 0 to 100.

width
Represents the value that indicates the dimension of the vignette object in pixels.

vignetteColor
Represents the value that specifies the vignette object color.

flags
Enumeration that specifies how to apply the Vignette effect.

Example

Run the VignetteCommand on an image.

C#
VB
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
 
public void VignetteConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")); 
 
   // Prepare the command 
   VignetteCommand command = new VignetteCommand(new LeadPoint((image.Width / 2), (image.Height / 2)), 50, 100, 20, 20, new RasterColor(0, 0, 0), VignetteCommandFlags.Ellipse | VignetteCommandFlags.Fillin); 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24); 
 
} 
 
static class LEAD_VARS 
{ 
   public const string ImagesDir = @"C:\Users\Public\Documents\LEADTOOLS Images"; 
} 
Imports Leadtools 
Imports Leadtools.Codecs 
Imports Leadtools.ImageProcessing.SpecialEffects

   Dim codecs As New RasterCodecs() 
   codecs.ThrowExceptionsOnInvalidImages = True 
 
   Dim leadImage As RasterImage = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "IMAGE1.CMP")) 
 
   ' Prepare the command 
   Dim command As VignetteCommand = New VignetteCommand(New LeadPoint(leadImage.Width \ 2, leadImage.Height \ 2), 50, 100, 20, 20, New RasterColor(0, 0, 0), VignetteCommandFlags.Ellipse Or VignetteCommandFlags.Fillin) 
   command.Run(leadImage) 
   codecs.Save(leadImage, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24) 
 
End Sub 
 
Public NotInheritable Class LEAD_VARS 
   Public Const ImagesDir As String = "C:\Users\Public\Documents\LEADTOOLS Images" 
End Class
