Interface LabelPlacement

All Known Implementing Classes:

LabelPlacement_Impl

public interface LabelPlacement

Used to position a label relative to a point or a line string. For a point, you can specify the anchor point of the label and a linear displacement from the point (so that you can also plot a graphic symbol at the point). For a line-string placement, you can specify a perpendicular offset (so you can draw a stroke on the line). MORE PARAMETERS ARE PROBABLY NEEDED HERE.

Method Summary

LinePlacement	getLinePlacement() For a LinePlacement, a perpendicular offset can be specified, to allow the line itself to be plotted also.
PointPlacement	getPointPlacement() 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.
void	setLinePlacement(LinePlacement linePlacement) sets
void	setPointPlacement(PointPlacement pointPlacement) Sets the PointPlacement for the Label.

Method Detail

getPointPlacement

public PointPlacement getPointPlacement()

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.

Returns:

the pointplacement for the label

setPointPlacement

public void setPointPlacement(PointPlacement pointPlacement)

Sets the PointPlacement for the Label.

Parameters:

pointPlacement - the pointplacement for the label

getLinePlacement

public LinePlacement getLinePlacement()

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.

Returns:

the lineplacement for the label

setLinePlacement

public void setLinePlacement(LinePlacement linePlacement)

sets

Parameters:

linePlacement - the lineplacement for the label
