Interface TextPlacement
- All Known Subinterfaces:
- LinePlacement, PointPlacement
public interface TextPlacement
Abstract base class for the two different classes that specify the placement of text
in a style, namely PointPlacement
and LinePlacement
.
For a PointPlacement
, the anchor point of the label and a linear displacement
from the point can be specified, to allow a graphic symbol to be plotted directly at
the point. This might be useful to label a city, for example. For a LinePlacement
,
a perpendicular offset can be specified, to allow the line itself to be plotted also. This
might be useful for labelling a road or a river, for example.
