Starting with Pencil+ 2.06, it is possible to set the value of [Antialiasing] for Lines to 0.
It is possible to output lines without anti-aliasing by setting [OverSampling] to 1 and [Antialiasing] to 0.
*The [Brush Type] in [Brush Details] must be set to [Simple].
It is not possible to completely remove anti-aliasing if the brush type is set to a value other than [Simple].
