Constructor & Destructor Documentation

◆ QgsPointCloudLayerElevationProperties()

QgsPointCloudLayerElevationProperties::QgsPointCloudLayerElevationProperties ( QObject * parent )

Constructor for QgsPointCloudLayerElevationProperties, with the specified parent object.

Definition at line 21 of file qgspointcloudlayerelevationproperties.cpp.

Member Function Documentation

◆ calculateZRange()

QgsDoubleRange QgsPointCloudLayerElevationProperties::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 54 of file qgspointcloudlayerelevationproperties.cpp.

◆ hasElevation()

bool QgsPointCloudLayerElevationProperties::hasElevation ( ) const

overridevirtual

Returns true if the layer has an elevation or z component.

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 26 of file qgspointcloudlayerelevationproperties.cpp.

◆ isVisibleInZRange()

bool QgsPointCloudLayerElevationProperties::isVisibleInZRange ( const QgsDoubleRange & range ) const

overridevirtual

Returns true if the layer should be visible and rendered for the specified z range.

Reimplemented from QgsMapLayerElevationProperties.

Definition at line 48 of file qgspointcloudlayerelevationproperties.cpp.

◆ readXml()

bool QgsPointCloudLayerElevationProperties::readXml	(	const QDomElement &	element,
		const QgsReadWriteContext &	context
	)

overridevirtual

Reads the elevation properties from a DOM element previously written by writeXml().

See also: writeXml()

Implements QgsMapLayerElevationProperties.

Definition at line 40 of file qgspointcloudlayerelevationproperties.cpp.

◆ setZOffset()

void QgsPointCloudLayerElevationProperties::setZOffset ( double offset )

inline

Sets the z offset, which is a fixed offset amount which will be added to z values from the layer.

This can be used to correct or manually adjust for incorrect elevation values in a point cloud layer.

Note: Any scaling specified via zScale() is applied before any offset value specified via zOffset()

See also: zOffset()

Definition at line 73 of file qgspointcloudlayerelevationproperties.h.

◆ setZScale()

void QgsPointCloudLayerElevationProperties::setZScale ( double scale )

inline

Sets the z scale, which is a scaling factor which will be applied to z values from the layer.

This can be used to correct or manually adjust for incorrect elevation values in a point cloud layer, such as conversion of elevation values in feet to meters.

Note: Any scaling specified via zScale() is applied before any offset value specified via zOffset()

See also: zScale()

Definition at line 99 of file qgspointcloudlayerelevationproperties.h.

◆ writeXml()

QDomElement QgsPointCloudLayerElevationProperties::writeXml	(	QDomElement &	element,
		QDomDocument &	doc,
		const QgsReadWriteContext &	context
	)

overridevirtual

Writes the properties to a DOM element, to be used later with readXml().

See also: readXml()

Implements QgsMapLayerElevationProperties.

Definition at line 31 of file qgspointcloudlayerelevationproperties.cpp.

◆ zOffset()

double QgsPointCloudLayerElevationProperties::zOffset ( ) const

inline

Returns the z offset, which is a fixed offset amount which should be added to z values from the layer.

This can be used to correct or manually adjust for incorrect elevation values in a point cloud layer.

Note: Any scaling specified via zScale() is applied before any offset value specified via zOffset()

See also: setZOffset()

Definition at line 61 of file qgspointcloudlayerelevationproperties.h.

◆ zScale()

double QgsPointCloudLayerElevationProperties::zScale ( ) const

inline

Returns the z scale, which is a scaling factor which should be applied to z values from the layer.

This can be used to correct or manually adjust for incorrect elevation values in a point cloud layer, such as conversion of elevation values in feet to meters.

Note: Any scaling specified via zScale() is applied before any offset value specified via zOffset()

See also: setZScale()
