Field Detail

xs

protected float[] xs

The array of x pixel coordinates.

ys

protected float[] ys

The array of y pixel coordinates.

Constructor Detail

PolygonGeometry.XY

protected PolygonGeometry.XY()

To satify the Offset constructor complaint.

PolygonGeometry.XY

public PolygonGeometry.XY(float[] xypoints)

Create an OMPoly from a list of xy pairs. If you want the poly to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:

xypoints - array of x/y points, arranged x, y, x, y, etc.

PolygonGeometry.XY

public PolygonGeometry.XY(float[] xPoints,
                          float[] yPoints)

Create an x/y OMPoly. If you want the poly to be connected, you need to ensure that the first and last coordinate pairs are the same.

Parameters:

xPoints - float[] of x coordinates

yPoints - float[] of y coordinates

Method Detail

setLocation

public void setLocation(float[] xypoints)

Set an OMPoly from a list of xy pixel pairs. If you want the poly to be connected, you need to ensure that the first and last coordinate pairs are the same. This is for RENDERTYPE_XY polys.

Parameters:

xypoints - array of x/y points, arranged x, y, x, y, etc.

setLocation

public void setLocation(float[] xPoints,
                        float[] yPoints)

Set an OMPoly from a x/y coordinates. If you want the poly to be connected, you need to ensure that the first and last coordinate pairs are the same. This is for RENDERTYPE_XY polys.

Parameters:

xPoints - float[] of x coordinates

yPoints - float[] of y coordinates

setXs

public void setXs(float[] x)

Set the array of x points.

getXs

public float[] getXs()

Get the array of x points.

setYs

public void setYs(float[] y)

Set the array of y points.

getYs

public float[] getYs()

Get the array of y points.

generate

public boolean generate(Projection proj)

Description copied from class: BasicGeometry

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

Specified by:

generate in class BasicGeometry

Parameters:

proj - Projection

Returns:

boolean true if successful, false if not.

BasicGeometry.regenerate(com.bbn.openmap.proj.Projection)

createShape

protected java.awt.geom.GeneralPath createShape()

Description copied from class: PolygonGeometry

Since OMPoly has the option to not create a Shape, this method is here to create it if it is asked for. The OMPoly needs to be generated.

Specified by:

createShape in class PolygonGeometry

getRenderType

public int getRenderType()

Description copied from class: BasicGeometry

Return the render type.

Specified by:

getRenderType in interface OMGeometry

Specified by:

getRenderType in class BasicGeometry

Returns:

the rendertype of the object - RENDERTYPE_LATLON, RENDERTYPE_XY, RENDERTYPE_OFFSET and RENDERTYPE_UNKNOWN.
