DotRemoveCommand(  
   DotRemoveCommandFlags flags, 
   int minimumDotWidth, 
   int minimumDotHeight, 
   int maximumDotWidth, 
   int maximumDotHeight 
)

Parameters

flags
Flag that determines the behavior of the dot removal process.

minimumDotWidth
The minimum width of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

minimumDotHeight
The minimum height of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

maximumDotWidth
The maximum width of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

maximumDotHeight
The maximum height of a dot to be removed. If the DotRemoveCommandFlags.UseDpi flag is set, units are in thousandths of an inch, otherwise units are in pixels.

Example

Run the DotRemoveCommand on an image.

   // Prepare the command 
   DotRemoveCommand command = new DotRemoveCommand(DotRemoveCommandFlags.UseSize | DotRemoveCommandFlags.SingleRegion, 1, 1, 10, 10); 
   command.DotRemove += new EventHandler<DotRemoveCommandEventArgs>(DotRemoveEvent_S2); 
   command.Run(image); 
 
}
