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.
