NAME

       plpsty - Select area fill pattern

SYNOPSIS

       plpsty(patt)

DESCRIPTION

       If  patt  is  zero  or  less  use  either  a  hardware solid fill if the drivers have that
       capability (virtually all do) or fall back to a software emulation of a solid  fill  using
       the  eighth area line fill pattern.  If 0 < patt <= 8, then select one of eight predefined
       area line fill patterns to use (see plpat(3plplot) if you desire other patterns).

       Redacted form: plpsty(patt)

       This function is used in examples 12, 13, 15, 16, and 25.

ARGUMENTS

       patt (PLINT(3plplot), input)
              The desired pattern index. If patt is zero or less, then a solid fill is (normally,
              see  qualifiers  above)  used.   For patt in the range from 1 to 8 and assuming the
              driver has not supplied line fill capability itself (most deliberately  do  not  so
              that  line fill patterns look identical for those drivers), the patterns consist of
              (1) horizontal lines, (2) vertical lines, (3) lines at 45 degrees, (4) lines at -45
              degrees,  (5)  lines at 30 degrees, (6) lines at -30 degrees, (7) both vertical and
              horizontal lines, and (8) lines at both 45 degrees and -45 degrees.
