Linetyp_attributes

  Defaultwerte siehe Hauptdoku "Farben, Linientypen, Strichstärken".


// Modify or create new line-Attribute:
  DL_InitAttRec ((int)AttributIndex,(int)color,(int)linetyp,(int)thick);
    // color:   2=red, 3=green, 4=blue
    // linetyp: 0=____, 1=_._, 2=__ __ 3=--
    // thick:   1-6
    
    // Defaults see File <tempDir>/ltyp.rc

  // Example: Attribut 20 = blue, long dash, thickness 3:
  DL_InitAttRec (20, 4, 2, 3);

  // use this att for line:
  Line      ln1={{0.,  0., 0.},{10., 5., 0.}};
  GR_Disp_ln (&ln1, 20);
  
  
  // restore defaultRecords from file <tempDir>/ltyp.rc
  DL_InitAttTab ();
