Field Detail

COORDMODE_ORIGIN

public static final int COORDMODE_ORIGIN

Translation offsets. The xy points are relative to the position of fixed latlon point.

See Also:

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

                        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.

                        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.

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.
