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.
