QgsRange which stores a range of double values.
Definition: qgsrange.h:203
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 bool showByDefaultInElevationProfilePlots() const
Returns true if the layer should be visible by default in newly created elevation profile plots.
virtual QDomElement writeXml(QDomElement &element, QDomDocument &doc, const QgsReadWriteContext &context)=0

Attempts to calculate the overall elevation or z range for the specified layer, using the settings de...
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.
virtual bool isVisibleInZRange(const QgsDoubleRange &range) const
Returns true if the layer should be visible and rendered for the specified z range.
Base class for all map layer types.

Point cloud layer specific subclass of QgsMapLayerElevationProperties.
bool respectLayerColors() const
Returns true if layer coloring should be respected when rendering elevation profile plots.

double maximumScreenError() const
Returns the maximum screen error allowed when generating elevation profiles for the point cloud.
The class is used as a container of context for various read/write operations on other objects.
