Description

Scales the co-ordinate system for all subsequent drawing operations. A scale factor of 1 is equivalent to calling SetGlobalMeasurementUnits(0) which sets the measurement units to be Points. A scale factor of (72 / 25.4) is equivalent to calling SetGlobalMeasurementUnits(1) which sets the measurement units to be millimetres.
