Class PolyLabelReducerListener

java.lang.Object
  org.free.garminimg.utils.PolyLabelReducerListener

All Implemented Interfaces:

TransformedMapListener

public class PolyLabelReducerListener
extends java.lang.Object
implements TransformedMapListener

Usually, streets are split between more than one polyline. To avoid having a street name repeated more than once, you can use this filter.

Method Summary

void	addPoint(int type, int subType, int x, int y, Label label, boolean indexed) Will be called for every points.
void	addPoly(int type, int[] xPoints, int[] yPoints, int nbPoints, Label label, boolean line) Will be called for every polygons/lines.
void	clear()

Method Detail

addPoint

public void addPoint(int type,
                     int subType,
                     int x,
                     int y,
                     Label label,
                     boolean indexed)

Description copied from interface: TransformedMapListener

Will be called for every points.

Specified by:

addPoint in interface TransformedMapListener

Parameters:

type - Type of points (see ImgConstants.getPointDesc(int,int)).

subType - Sub type.

x - The X coordinate in pixels.

y - The Y coordinate in pixels.

label - The label attached to this point or null if there is none.

indexed - True if the point is indexed.

addPoly

public void addPoly(int type,
                    int[] xPoints,
                    int[] yPoints,
                    int nbPoints,
                    Label label,
                    boolean line)

Description copied from interface: TransformedMapListener

Will be called for every polygons/lines.

Specified by:

addPoly in interface TransformedMapListener

Parameters:

type - Type of polyline/gone (see ImgConstants.getPolyDesc(int,boolean)).

xPoints - The X coordinates in pixels. Don't keep a pointer on it for more than the duration of this call.

yPoints - Same as xPoints, but for y coordinates.

nbPoints - The number of points available.

label - The label attached to this poly or null if there is none.

line - True if it's a polyline, false if it's a polygon.

Specified by:

startMap in interface TransformedMapListener

Parameters:

file - The file.
