DotRemoveCommandEventArgs Constructor (DotRemoveCommandEventArgs)








Leadtools.ImageProcessing.Core Namespace > DotRemoveCommandEventArgs Class : DotRemoveCommandEventArgs Constructor
RasterImage object that references the image to be modified.
LEADTOOLS RasterRegion representing the dot to be removed. It is the programmer's responsibility to dispose of this region when it is no longer needed.
The bounding rectangle of the dot being processed.
Total number of white pixels in the dot being processed.
Total number of black pixels in the dot being processed.
Initializes a new DotRemoveCommand with explicit parameters.
Syntax
'Declaration
 

Public Function New( _
   ByVal image As RasterImage, _
   ByVal region As RasterRegion, _
   ByVal boundingRectangle As LeadRect, _
