Method Detail

export

String export(String format)

Return the string representation of projection in the format. Return null if can't export to format

Parameters:

format -

Returns:

getDatum

IDatum getDatum()

createPoint

Point2D createPoint(double x,
                    double y)

getAbrev

String getAbrev()

getFullCode

String getFullCode()

Devuelve getAbrev() mas los parametros de transformacion si los hay ej.: (EPSG:23030:proj@+proj...@...)

Returns:

getAbrev() o getAbrev()+parametros

drawGrid

void drawGrid(Graphics2D g,
              ViewPortData vp)

setGridColor

void setGridColor(Color c)

getGridColor

Color getGridColor()

getCT

ICoordTrans getCT(IProjection dest)

Crea un ICoordTrans para transformar coordenadas desde el IProjection actual al dest.

Parameters:

dest -

Returns:

toGeo

Point2D toGeo(Point2D pt)

fromGeo

Point2D fromGeo(Point2D gPt,
                Point2D mPt)

isProjected

boolean isProjected()

getScale

double getScale(double minX,
                double maxX,
                double width,
                double dpi)

First two parameters must be in meters. This should be changed (map units should be used) and then change the places where this method is used.

Parameters:

minX - in meters

maxX - in meters

width - in pixels (dots)

dpi - dots per inch

Returns:

Scale denominator ( the "X" in "1 : X" )

getExtent

Rectangle2D getExtent(Rectangle2D extent,
                      double scale,
                      double wImage,
                      double hImage,
                      double mapUnits,
                      double distanceUnits,
                      double dpi)
