PointList points,
Point therefPoint)
- Calculates the label offset from the reference point given the label bounds and a points
list.
- Parameters:
bounds
- the Rectangle
that is the bounding box of the labelpoints
- the PointList
that the label offset is relative totherefPoint
- the Point
that is the reference point that the offset is based on, or
null
- Returns:
- a
Point
which represents a value offset from the refPoint
point
oriented based on the nearest line segment, or null
if no such point can be
