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 91 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
tolerancetolerance value to be translated
layerreference layer
mapSettingssettings of the map
unitstype of units to be translated
Returns
value of tolerance in layer units

Definition at line 56 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
tolerancetolerance value to be translated
layersource layer necessary in case tolerance is in layer units
mapSettingssettings of the map
unitstype of units to be translated
Returns
value of tolerance in map units

Definition at line 41 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 75 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 84 of file qgstolerance.cpp.
