This file contains the headers for AbstractProjection.
A base class for all projections in Marble.
bool screenCoordinates(const qreal lon, const qreal lat, const ViewportParams *viewport, qreal &x, qreal &y) const
Get the screen coordinates corresponding to geographical coordinates in the map.
A base class for the Gnomonic and Orthographic (Globe) projections in Marble.
bool isClippedToSphere() const override
Defines whether a projection is supposed to be clipped to a certain radius.
GeoDataLatLonAltBox latLonAltBox(const QRect &screenRect, const ViewportParams *viewport) const override
Returns a GeoDataLatLonAltBox bounding box of the given screenrect inside the given viewport.
bool mapCoversViewport(const ViewportParams *viewport) const override
Returns whether the projected data fully obstructs the current viewport.
bool repeatableX() const override
Returns whether the projection allows for wrapping in x direction (along the longitude scale).
QPainterPath mapShape(const ViewportParams *viewport) const override
Returns the shape/outline of a map projection.
bool traversablePoles() const override
Returns whether the projection allows to navigate seamlessly "over" the pole.
Binds a QML item to a specific geodetic location in screen coordinates.
