PTYPE

 Default value:  PTYPE = 0.0

 PTYPE controls whether graphics pixels are turned on, off, or
 toggled.  This can be used to selectively erase graphics, by
 drawing with PTYPE = 0.0 and redrawing with PTYPE = 1.0; or by
 drawing and redrawing with PTYPE = 2.0. This only works on the
 monitor screen and on bitmap hardcopy output.

 PTYPE = 0.0 - pixels are turned on ( draw )
 PTYPE = 1.0 - pixels are turned off ( erase )
 PTYPE = 2.0 - pixels are complemented, that is, 
               if currently on, turn off; 
               if currently off, turn on

LINTHK

 Default value:  LINTHK = 1.0 

 LINTHK controls the line thickness for bitmap hardcopy output
 and for PostScript hardcopy output.  It has no affect on what
 is displayed on a terminal screen or on a pen plotter.  

 The following line-thickening algorithm is for bitmap hardcopies
 only. The line width in pixels is set by LINTHK. The "brush"
 used is a square of LINTHK x LINTHK pixels.  The round brush
 option is enabled by making LINTHK negative and makes a
 difference only with widths of 4 pixels or more.  Compared to
 the square brush, the round brush gives a more consistent line
 width for lines of different angles.

XLWIND

 Default value:  %XLWIND = 0.0 

 XLWIND determines the left edge of the GPLOT window.  There are
 two forms:

 XLWIND  -- is the left edge of the GPLOT window,
             in world coordinate units
 %XLWIND -- is the left edge, window, expressed as a
             percentage of the width of the world window,
             that is, XLWIND=XMINHP+%XLWIND*(XMAXHP-XMINHP)/100

XUWIND

 Default value:  %XUWIND = 100.0 

 XUWIND determines the right edge of the GPLOT  window.  There
 are two forms:

 XUWIND  -- is the right edge of the GPLOT
             window, in world coordinate units
 %XUWIND -- is the right edge, expressed as a
             percentage of the width of the world window,
             that is, XUWIND=XMINHP+%XUWIND*(XMAXHP-XMINHP)/100  

YLWIND

 Default value:  %YLWIND = 0.0 

 YLWIND determines the lower edge of the GPLOT window. There are
 two forms:

 YLWIND  -- is the lower edge of the plot window, in 
             world coordinate units
 %YLWIND -- is the lower edge, expressed as a
             percentage of the height of the world window,
             that is, YLWIND=YMINHP+%YLWIND*(YMAXHP-YMINHP)/100  

YUWIND

 Default value:  %YUWIND = 100.0 

 YUWIND determines the upper edge of the GPLOT  window. There are
 two forms:

 YUWIND  -- is the upper edge of the plot window, in 
             world coordinate units  
 %YUWIND -- is the upper edge, expressed as a
             percentage of the height of the world window,
             that is, YUWIND=YMINHP+%YUWIND*(YMAXHP-YMINHP)/100
