public InvertedTextCommandEventArgs( 
   RasterImage image,
   RasterRegion region,
   LeadRect boundingRectangle,
   int whiteCount,
   int blackCount
)

'Declaration
 
Public Function New( _
   ByVal image As RasterImage, _
   ByVal region As RasterRegion, _
   ByVal boundingRectangle As LeadRect, _
   ByVal whiteCount As Integer, _
   ByVal blackCount As Integer _
)

'Usage
 
Dim image As RasterImage
Dim region As RasterRegion
Dim boundingRectangle As LeadRect
Dim whiteCount As Integer
Dim blackCount As Integer
 
Dim instance As New InvertedTextCommandEventArgs(image, region, boundingRectangle, whiteCount, blackCount)

public InvertedTextCommandEventArgs( 
   RasterImage image,
   RasterRegion region,
   LeadRect boundingRectangle,
   int whiteCount,
   int blackCount
)

function InvertedTextCommandEventArgs( 
   image ,
   region ,
   boundingRectangle ,
   whiteCount ,
   blackCount 
)

public:
InvertedTextCommandEventArgs( 
   RasterImage^ image,
   RasterRegion^ region,
   LeadRect boundingRectangle,
   int whiteCount,
   int blackCount
)

Parameters

image: RasterImage object that references the affected image.
region: LEADTOOLS Leadtools.RasterRegion representing the inverted text to be removed. Dispose of this region when it is no longer needed.
boundingRectangle: The bounding rectangle of the inverted text region being processed.
whiteCount: Total number of white pixels in the inverted text region being processed.
blackCount: Total number of black pixels in the inverted text region being processed.
