The Qgis class provides global constants for use throughout the application.
Definition qgis.h:54
MeshElevationMode
Mesh layer elevation modes.
Definition qgis.h:3461
@ FromVertices
Elevation should be taken from mesh vertices.
ProfileSurfaceSymbology
Surface symbology type for elevation profile plots.
Definition qgis.h:3606
@ Line
The elevation surface will be rendered using a line symbol.
QgsRange which stores a range of double values.
Definition qgsrange.h:231
A fill symbol type, for rendering Polygon and MultiPolygon geometries.
A line symbol type, for rendering LineString and MultiLineString geometries.
Base class for storage of map layer elevation properties.
virtual QgsMapLayerElevationProperties * clone() const =0
Creates a clone of the properties.
virtual QString htmlSummary() const
Returns a HTML formatted summary of the properties.
virtual QDomElement writeXml(QDomElement &element, QDomDocument &doc, const QgsReadWriteContext &context)=0
Writes the properties to a DOM element, to be used later with readXml().
virtual bool readXml(const QDomElement &element, const QgsReadWriteContext &context)=0
Reads the elevation properties from a DOM element previously written by writeXml().
virtual bool hasElevation() const
Returns true if the layer has an elevation or z component.
Base class for all map layer types.
Definition qgsmaplayer.h:75
Mesh layer specific subclass of QgsMapLayerElevationProperties.
The class is used as a container of context for various read/write operations on other objects.
