Specified by:

getMapImage in interface MapData

Parameters:

centerPhi - the phi center location of the map.

centerTheta - the theta center location of the map.

Returns:

The map image.

getRGBColor

public Color getRGBColor(double phi,
                         double theta)

Description copied from interface: MapData

Gets the RGB map color at a given location.

Specified by:

getRGBColor in interface MapData

Parameters:

phi - the phi location.

theta - the theta location.

Returns:

the RGB map color.

findRectPosition

public Point findRectPosition(double oldPhi,
                              double oldTheta,
                              double newPhi,
                              double newTheta,
                              double rho,

                              int low_edge)

Converts spherical coordinates to rectangular coordinates. Returns integer x and y display coordinates for spherical location.

Parameters:

newPhi - the new phi coordinate

newTheta - the new theta coordinate

rho - diameter of planet (in km)

half_map - half the map's width (in pixels)

low_edge - lower edge of map (in pixels)

Returns:

pixel offset value for map
