Member Function Documentation

defaultTolerance()

double QgsTolerance::defaultTolerance ( QgsMapLayer *  layer, const QgsMapSettings &  mapSettings  )

static

Static function to get default tolerance value for a layer.

The value is read from settings and transformed if necessary.

Returns

value of default tolerance in layer units

Definition at line 92 of file qgstolerance.cpp.

toleranceInMapUnits()

double QgsTolerance::toleranceInMapUnits ( double  tolerance, QgsMapLayer *  layer, const QgsMapSettings &  mapSettings, Qgis::MapToolUnit  units = Qgis::MapToolUnit::Layer  )

static

Static function to translate tolerance value into layer units.

Parameters

tolerance	tolerance value to be translated
layer	reference layer
mapSettings	settings of the map
units	type of units to be translated

Returns

value of tolerance in layer units

Definition at line 57 of file qgstolerance.cpp.

toleranceInProjectUnits()

double QgsTolerance::toleranceInProjectUnits ( double  tolerance, QgsMapLayer *  layer, const QgsMapSettings &  mapSettings, Qgis::MapToolUnit  units  )

static

Static function to translate tolerance value into map units.

Parameters

tolerance	tolerance value to be translated
layer	source layer necessary in case tolerance is in layer units
mapSettings	settings of the map
units	type of units to be translated

Returns

value of tolerance in map units

Definition at line 42 of file qgstolerance.cpp.

vertexSearchRadius() [1/2]

double QgsTolerance::vertexSearchRadius ( const QgsMapSettings &  mapSettings )

static

Static function to get vertex tolerance value.

The value is read from settings and transformed if necessary.

Returns

value of vertex tolerance in map units (not layer units)

Definition at line 76 of file qgstolerance.cpp.

vertexSearchRadius() [2/2]

double QgsTolerance::vertexSearchRadius ( QgsMapLayer *  layer, const QgsMapSettings &  mapSettings  )

static

Static function to get vertex tolerance value for a layer.

The value is read from settings and transformed if necessary.

Returns

value of vertex tolerance in layer units

Definition at line 85 of file qgstolerance.cpp.
