A geometry is the spatial representation of a feature.
Base class for all map layer types.
Generates and renders elevation profile plots.
Encapsulates a QGIS project, including sets of map layers and their styles, layouts,...
This class implements a visual Qt Quick Item that does elevation profile rendering according to the c...
QgsGeometry profileCurve() const
Returns the profile curve geometry.
void activeJobCountChanged(int count)
Emitted when the number of active background jobs changes.
void crsChanged()
Emitted when the CRS linked to the profile curve geometry changes.
QgsCoordinateReferenceSystem crs() const
Returns the crs associated with map coordinates.
void profileCurveChanged()
