AbstractProjection Class Reference

from PyKDE4.marble import *

Namespace: Marble

Detailed Description

Abstract class:
This class can be used as a base class for new classes, but can not be instantiated directly.

A base class for all projections in Marble.

Method Documentation

__init__ (   self )

Construct a new AbstractProjection.

bool exceedsLatitudeRange (  self,
Marble.GeoDataCoordinates  coords
)
bool exceedsLatitudeRange (  self,
Marble.GeoDataLineString  lineString
)
bool geoCoordinates (  self,
int  x,
int  y,
Marble.ViewportParams  viewport,
float  lon,
float  lat,
Marble.GeoDataCoordinates.Unit  unit=Marble.GeoDataCoordinates.Degree
)
Abstract method:
This method is abstract and can be overridden but not called directly.

Get the earth coordinates corresponding to a pixel in the map.

Parameters:
x  the x coordinate of the pixel
y  the y coordinate of the pixel
viewport  the viewport parameters
lon  the longitude angle is returned through this parameter
lat  the latitude angle is returned through this parameter
unit  the unit of the angles for lon and lat.

Returns:
true if the pixel (x, y) is within the globe
false if the pixel (x, y) is outside the globe, i.e. in space.
