class qgis.core.QgsMapUnitScale

Bases: sip.wrapper

Struct for storing maximum and minimum scales for measurements in map units

For measurements in map units, a minimum and a maximum scale can be defined. Outside this range, the measurements aren’t scaled anymore proportionally to the map scale.

computeMapUnitsPerPixel(self, c: QgsRenderContext) → float

Computes a map units per pixel scaling factor, respecting the minimum and maximum scales set for the object.

Parameters:c – render context
Returns:map units per pixel, limited between minimum and maximum scales
