Class: QgsMeshRendererVectorWindBarbSettings¶

Represents a mesh renderer settings for vector datasets displayed with wind barbs.

Note

The API is considered EXPERIMENTAL and can be changed without a notice

Added in version 3.38.

class qgis.core.QgsMeshRendererVectorWindBarbSettings[source]¶

Bases: object

class WindSpeedUnit(*values)¶

Bases: IntEnum

Wind speed units. Wind barbs use knots so we use this enum for preset conversion values

MetersPerSecond: Meters per second
KilometersPerHour: Kilometers per hour
Knots: Knots (Nautical miles per hour)
MilesPerHour: Miles per hour
FeetPerSecond: Feet per second
OtherUnit: Other unit

FeetPerSecond = 4¶

KilometersPerHour = 1¶

Knots = 2¶

MetersPerSecond = 0¶

MilesPerHour = 3¶

OtherUnit = 5¶

magnitudeMultiplier(self) → float[source]¶

Returns the multiplier for the magnitude to convert it to knots, according to the units set with setMagnitudeUnits() A custom multiplier can be set with setMagnitudeMultiplier() for the case when units are set to OtherUnit

Return type:: float

magnitudeUnits(self) → QgsMeshRendererVectorWindBarbSettings.WindSpeedUnit[source]¶

Returns the units that the data are in

Return type:: QgsMeshRendererVectorWindBarbSettings.WindSpeedUnit

readXml(self, elem: QDomElement)[source]¶

Reads configuration from the given DOM element

Parameters:: elem (QDomElement)

setMagnitudeMultiplier(self, magnitudeMultiplier: float)[source]¶

Sets a multiplier for the magnitude to convert it to knots

Parameters:: magnitudeMultiplier (float)

setMagnitudeUnits(self, units: QgsMeshRendererVectorWindBarbSettings.WindSpeedUnit)[source]¶

Sets the units that the data are in

Parameters:: units (QgsMeshRendererVectorWindBarbSettings.WindSpeedUnit)

setShaftLength(self, shaftLength: float)[source]¶

Sets the shaft length (in millimeters)

Parameters:: shaftLength (float)

setShaftLengthUnits(self, shaftLengthUnit: Qgis.RenderUnit)[source]¶

Sets the units for the shaft length.
