HolePunchRemoveCommandEventArgs Constructor (HolePunchRemoveCommandEventArgs)

Summary

Initializes a new HolePunchRemoveCommand class object with explicit parameters.

Syntax

WinRT C#

C++

public HolePunchRemoveCommandEventArgs(  
   Leadtools.RasterImage image, 
   Leadtools.RasterRegion region, 
   Leadtools.LeadRect boundingRectangle, 
   int holeIndex, 
   int holeTotalCount, 
   int whiteCount, 
   int blackCount 
)

Public Function New( _ 
   ByVal image As Leadtools.RasterImage, _ 
   ByVal region As Leadtools.RasterRegion, _ 
   ByVal boundingRectangle As Leadtools.LeadRect, _ 
   ByVal holeIndex As Integer, _ 
   ByVal holeTotalCount As Integer, _ 
   ByVal whiteCount As Integer, _ 
   ByVal blackCount As Integer _ 
)

public HolePunchRemoveCommandEventArgs(  
   Leadtools.RasterImage image, 
   Leadtools.RasterRegion region, 
   Leadtools.LeadRect boundingRectangle, 
   int holeIndex, 
   int holeTotalCount, 
   int whiteCount, 
   int blackCount 
)

function HolePunchRemoveCommandEventArgs(  
   image , 
   region , 
   boundingRectangle , 
   holeIndex , 
   holeTotalCount , 
   whiteCount , 
   blackCount  
)

public: 
HolePunchRemoveCommandEventArgs(  
   Leadtools.RasterImage^ image, 
   Leadtools.RasterRegion^ region, 
   Leadtools.LeadRect boundingRectangle, 
   int holeIndex, 
   int holeTotalCount, 
   int whiteCount, 
   int blackCount 
)

Parameters

image
RasterImage object that contains the affected image

region
LEADTOOLS RasterRegion representing one of the holes of the hole punch pattern. It is the programmer's responsibility to dispose of this region when it is no longer needed.

boundingRectangle
The bounding rectangle of one of the holes in a hole punch pattern.

holeIndex
Index of the hole within a hole punch pattern. The holes are numbered from 1 to n, where n is the total number of holes in the hole punch pattern.

holeTotalCount
The total number of holes that make up the hole punch pattern. This value will not change for a particular call to HolePunchRemoveCommand.

whiteCount
Total number of white pixels in one of the holes of a hole punch pattern.

blackCount
Total number of black pixels in one of the holes of a hole punch pattern.

Example

Run the HolePunchRemoveCommand on an image.
