- class qgis.core.QgsProcessingParameterScale¶
Bases:
QgsProcessingParameterNumber
A double numeric parameter for map scale values.
QgsProcessingParameterScale
should be evaluated by callingQgsProcessingAlgorithm.parameterAsDouble()
, which will return a numeric value representing the scale denominator.Added in version 3.8.
