FreeRadialBendCommand Constructor(int[],int,LeadPoint,RasterColor,FreeRadialBendCommandFlags)

Summary

Initializes a new FreeRadialBendCommand class object with explicit parameters.

Syntax
C#
VB
C++
  
Public Function New( _ 
   ByVal curve() As Integer, _ 
   ByVal scale As Integer, _ 
   ByVal centerPoint As LeadPoint, _ 
   ByVal fillColor As RasterColor, _ 
   ByVal flags As FreeRadialBendCommandFlags _ 
) 
public: 
FreeRadialBendCommand(  
   array<int>^ curve, 
   int scale, 
   LeadPoint centerPoint, 
   RasterColor fillColor, 
   FreeRadialBendCommandFlags flags 
) 

Parameters

curve
Array of integers that represent surface shape values. Valid values for each element in the Curve array range between -1000 and 1000. Positive values mean the curve is concave in and negative values mean the curve is concave out. The values in this array are internally divided by 1000.

scale
Factor used to multiply the various amplitude values in the Curve array. Each value in the Curve array is multiplied by this factor. For example, if you want to double the size of the amplitude values, use a Scale value of 2; to triple the amplitudes values, use a Scale value of 3, etc. The top practical limit for this parameter is the width and height of the Run method image. This parameter only accepts positive values.

centerPoint
Contains the surface center.

fillColor
Specifies the fill color for any exposed areas.

flags
Flags that indicate how to handle peripherally exposed areas and areas exposed inside the surface.

Example

Run the FreeRadialBendCommand on an image.
