getPOrig

public IProjection getPOrig()

Specified by:

getPOrig in interface ICoordTrans

getPDest

public IProjection getPDest()

Specified by:

getPDest in interface ICoordTrans

convert

public Point2D convert(Point2D ptOrig,
                       Point2D ptDest)
                throws CoordTransRuntimeException

Specified by:

convert in interface ICoordTrans

Throws:

CoordTransRuntimeException

convert

public Rectangle2D convert(Rectangle2D rect)
                    throws CoordTransRuntimeException

Description copied from interface: ICoordTrans

Reprojects the input rectangle and returns the minimum rectangle containing the result of that reprojection (which was not necessarily a rectangle). Reprojecting the diagonal an assuming that the result is the diagonal of the rectangle to be returned is wrong Reprojecting the four corners and searching for min and max to create the resulting rectangle is not completely accurate but provides an acceptable approximation

Specified by:

convert in interface ICoordTrans

Returns:

Throws:

CoordTransRuntimeException

getInverted

public ICoordTrans getInverted()

Specified by:

getInverted in interface ICoordTrans
