PunchCommand Constructor(Int32,Int32,LeadPoint,RasterColor,PunchCommandFlags)

Summary

Initializes a new PunchCommand class object with explicit parameters.

Syntax

C#
VB
WinRT C#
C++
Public Function New( _ 
   ByVal value As Integer, _ 
   ByVal stress As Integer, _ 
   ByVal centerPoint As Leadtools.LeadPoint, _ 
   ByVal fillColor As Leadtools.RasterColor, _ 
   ByVal flags As Leadtools.Imageprocessing.Specialeffects.PunchCommandFlags _ 
) 
function PunchCommand(  
   value , 
   stress , 
   centerPoint , 
   fillColor , 
   flags  
) 

Parameters

value
Amount of stretching where :

Positive values: pinch the image toward its center. Negative values: expand the image away from its center. Valid values range from -500 to 500.

stress
Amount of punching intensity. This value is ignored when the value parameter is less than 0. Valid values range from 0 to 1000.

centerPoint
The point around which the image will be pinched or punched.

fillColor
Specifies the fill color for any exposed areas.

flags
Flags that indicate how to handle exposed areas, both centrally and peripherally.

Example

Run the PunchCommand on an image.
