Member Function Documentation

◆ calculateZRange()

QgsDoubleRange QgsMeshLayerElevationProperties::calculateZRange ( QgsMapLayer layer) const
overridevirtual

Attempts to calculate the overall elevation or z range for the specified layer, using the settings defined by this elevation properties object.

May return an infinite range if the extent could not be calculated.

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 164 of file qgsmeshlayerelevationproperties.cpp.

◆ clone()

QgsMeshLayerElevationProperties * QgsMeshLayerElevationProperties::clone ( ) const
overridevirtual

Creates a clone of the properties.

Since
QGIS 3.26

Implements QgsMapLayerElevationProperties.

Definition at line 137 of file qgsmeshlayerelevationproperties.cpp.

◆ elevationLimit()

double QgsMeshLayerElevationProperties::elevationLimit ( ) const

Returns the elevation limit, which is used when profileSymbology() is Qgis::ProfileSurfaceSymbology::FillBelow or Qgis::ProfileSurfaceSymbology::FillAbove to limit the fill to a specific elevation range.

By default this is NaN, which indicates that there is no elevation limit.

See also
