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.
