- All Implemented Interfaces:
- java.lang.Cloneable, OMGeometry, OMGraphicConstants, java.io.Serializable
- public class OMEllipse
- extends OMCircle
The OMEllipse is a lat/lon ellipse, made up of a center lat/lon
point, and some length described for the x and y axis. If you want
to create ellipses in X/Y space, use OMCircle. Ellipse arcs are not
available yet, and this class doesn't really work with the
EditableOMCircle. You can use EditableOMCircles to move and delete
OMEllipses, but you can't change the axis dimensions.

OMEllipse
public OMEllipse(LatLonPoint centerPoint,
double majorAxisSpan,
double minorAxisSpan,
Length units,
double rotateAngle)
setAxis
public void setAxis(double majorAxis,
double minorAxis,
Length units)
- Set the axis lengths of the ellipse.
- Parameters:
majorAxis
- x direction of ellipse.minorAxis
- y direction of ellipse.units
- com.bbn.openmap.proj.Length object describing
units of axis values.
setCenter
public void setCenter(LatLonPoint llp)
- Description copied from class:
OMArc
- Set the latitude and longitude of the center point. This is
meaningful only if the rendertype is RENDERTYPE_LATLON or
RENDERTYPE_OFFSET.
- Overrides:
setCenter
in class OMArc
- Parameters:
llp
- LatLonPoint of center.
getMajorAxis
public double getMajorAxis()
- Get the x axis value.
getMinorAxis
public double getMinorAxis()
- Get the y axis value.
getLatLonPoints
public float[] getLatLonPoints()
- Get the float[] of points that make up the ellipse. In radians,
lat, lon, lat, lon, etc. May be null if generate hasn't been
called.
createLatLonPoints
public float[] createLatLonPoints()
- Given that the center point and the axis are set, calculate the
new lat/lon points all around the ellipse from the center.
generate
public boolean generate(Projection proj)
- Description copied from class:
OMArc
- Prepare the arc for rendering.
- Specified by:
generate
in interface OMGeometry
- Overrides:
generate
in class OMArc
- Parameters:
proj
- Projection
- Returns:
- true if generate was successful
