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
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.
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
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
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
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
