Summary

Initializes a new PunchCommand class object with explicit parameters.

Syntax
C#
VB
C++
  
Public Function New( _ 
   ByVal value As Integer, _ 
   ByVal stress As Integer, _ 
   ByVal centerPoint As LeadPoint, _ 
   ByVal fillColor As RasterColor, _ 
   ByVal flags As PunchCommandFlags _ 
) 
public: 
PunchCommand(  
   int value, 
   int stress, 
   LeadPoint centerPoint, 
   RasterColor fillColor, 
   PunchCommandFlags 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.

VB

public void PunchConstructorExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs();

   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   PunchCommand command = new PunchCommand(100, 100, new LeadPoint((image.Width / 2), (image.Height / 2)), new RasterColor(0, 0, 0), PunchCommandFlags.Repeat | PunchCommandFlags.WithoutRotate); 
   // punch the image. 
   command.Run(image); 
   codecs.Save(image, Path.Combine(LEAD_VARS.ImagesDir, "Result.jpg"), RasterImageFormat.Jpeg, 24);
