Field Detail

COORDMODE_ORIGIN

public static final int COORDMODE_ORIGIN
Translation offsets. The xy points are relative to the position of fixed latlon point.

Constant Field Values

COORDMODE_PREVIOUS

public static final int COORDMODE_PREVIOUS
Delta offsets. Each xy point in the array is relative to the previous point, and the first point is relative to the fixed latlon point.

See Also:
Constant Field Values

lat

protected float lat
The latitude of the starting point of the poly. Stored as radians!


lon

protected float lon
The longitude of the starting point of the poly. Stored as radians!


coordMode

protected int coordMode
Type of offset.

COORDMODE_ORIGIN, COORDMODE_PREVIOUS
Constructor Detail

PolygonGeometry.Offset

public PolygonGeometry.Offset(float latPoint,
                              float lonPoint,
                              int[] xypoints,
                              int cMode)
Create an x/y OMPoly at an offset from lat/lon. If you want the poly to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:
latPoint - latitude in decimal degrees
lonPoint - longitude in decimal degrees
xypoints - int[] of x,y pairs
cMode - offset coordinate mode

PolygonGeometry.Offset

public PolygonGeometry.Offset(float latPoint,
                              float lonPoint,
                              int[] xPoints,
                              int[] yPoints,
                              int cMode)
Create an x/y OMPoly at an offset from lat/lon. If you want the poly to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:
latPoint - latitude in decimal degrees
lonPoint - longitude in decimal degrees
xPoints - int[] of x coordinates
yPoints - int[] of y coordinates
cMode - offset coordinate mode

setLocation

public void setLocation(float latPoint,
                        float lonPoint,
                        int units,
                        int[] xypoints)
Set the location based on a latitude, longitude, and some xy points. The coordinate mode and the polygon setting are the same as in the constructor used.

Parameters:
latPoint - latitude in decimal degrees.
lonPoint - longitude in decimal degrees.
units - radians or decimal degrees. Use OMGraphic.RADIANS or OMGraphic.DECIMAL_DEGREES
xypoints - array of x/y points, arranged x, y, x, y, etc.

setLocation

                        int[] xPoints,
                        int[] yPoints)
Set the location based on a latitude, longitude, and some xy points. The coordinate mode and the polygon setting are the same as in the constructor used.

Parameters:
latPoint - latitude in decimal degrees
lonPoint - longitude in decimal degrees
units - radians or decimal degrees. Use OMGraphic.RADIANS or OMGraphic.DECIMAL_DEGREES
xPoints - int[] of x coordinates
yPoints - int[] of y coordinates

setCoordMode

public void setCoordMode(int coordMode)
Type of offset.

COORDMODE_ORIGIN, COORDMODE_PREVIOUS

getCoordMode

public int getCoordMode()
Type of offset.

See Also:
COORDMODE_ORIGIN, COORDMODE_PREVIOUS

setLat

public void setLat(float lat)
Set the latitude of the offset point, in decimal degrees.


getLat

public float getLat()
Get the latitude of the offset point, in decimal degrees.


setLon

public void setLon(float lon)
Set the longitude of the offset point, in decimal degrees.


getLon

public float getLon()
Get the longitude of the offset point, in decimal degrees.


generate

public boolean generate(Projection proj)
Description copied from interface: OMGeometry
Prepare the geometry for rendering. This must be done before calling render()! If a vector graphic has lat-lon components, then we project these vertices into x-y space. For raster graphics we prepare in a different fashion.

If the generate is unsuccessful, it's usually because of some oversight, (for instance if proj is null), and if debugging is enabled, a message may be output to the controlling terminal.

Specified by:
generate in interface OMGeometry
Overrides:
generate in class PolygonGeometry.XY
Parameters:
proj - Projection
Returns:
boolean true if successful, false if not.
See Also:
OMGeometry.regenerate(com.bbn.openmap.proj.Projection)

getRenderType

public int getRenderType()
Description copied from interface: OMGeometry
Return the render type.

Specified by:
getRenderType in interface OMGeometry
Overrides:
getRenderType in class PolygonGeometry.XY
Returns:
the rendertype of the object - RENDERTYPE_LATLON, RENDERTYPE_XY, RENDERTYPE_OFFSET and RENDERTYPE_UNKNOWN.
