class Driver from PS inherits PlotterDriver from PlotMgt
---Purpose: This class defines a PS (Adobe PostScript) plotter Driver.
--- All necessary information about methods (purpose, level, category, etc.)
--- can be found in CDL files from the inheritance tree (PlotMgt_PlotterDriver,
--- Aspect_Driver).

-- - returns the DPU coordinates (DX,DY)
-- corresponding to the pixel position (PX,PY), or
-- - returns the pixel position (PX,PY) corresponding to
-- the DPU coordinates (DX,DY).
-- The DPU value is specified in millimeters by default.
-- Warning
-- The pixel size is 325mm/1152 by default and can be
-- changed with the SetPixelSize function.
