Member Enumeration Documentation

◆ WindSpeedUnit

enum class QgsMeshRendererVectorWindBarbSettings::WindSpeedUnit

strong

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

Enumerator
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.

◆ magnitudeMultiplier()

double QgsMeshRendererVectorWindBarbSettings::magnitudeMultiplier ( ) const

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.
