WNT_DDriver.cxx

// File:        WNT_DDriver.cxx
// Created:     Mon Mar 17 17:28:42 1997
// Author:      EugenyPLOTNIKOV
// Modified:    MAR-98 MAY-98 (EUG & DCB) - study S3553
// DCB: 15-05-98 Changing the parent of WNT_DDriver from Aspect_Driver
//               to Aspect_PlotterDriver
// DCB: SEP-98  Avoid memory crash when color indices do not follow
//              each other or do not begin with '1'
// DCB: OCT-98  Changing the implementation of the constructors to
//              the standard for plotter drivers (constructor takes
//              the file name as a Standard_CString).
//              Changing the implementation of _dd_fill_buff() to fill
//              the EMF file description according to documentation:
//              <APP_Name\0Picture_Name\0\0> - see CreateEnhMetaFile() API.
//              It is possible now to create two files: EMF and PRN.
