NAME
       plmap - Plot continental outline in world coordinates.

SYNOPSIS
       plmap(mapform, type, minlong, maxlong, minlat, maxlat)

DESCRIPTION
       Plots continental outlines in world coordinates. examples/c/x19c demon-
       strates how to use this  function to create different projections.

       Redacted form:  General: plmap(mapform, type, minlong, maxlong, minlat,
       maxlat) F95, Java, Perl/PDL, Python: Not implemented?


       This function is used in example 19.

ARGUMENTS
       mapform (void (*) (PLINT, PLFLT *, PLFLT *), input)
              A user supplied function to transform the coordinate  longitudes
              and latitudes to a  plot  coordinate  system.    By  using  this
              transform,  we can change from a longitude,  latitude coordinate
              to a polar  stereographic  project,  for   example.   Initially,
              x[0]..[n-1]  are the longitudes and y[0]..y[n-1]  are the corre-
              sponding latitudes.  After the call to mapform(), x[]   and  y[]
              should  be  replaced by the corresponding plot coordinates.   If
              no transform is desired, mapform can be replaced by NULL.

       type (char *, input)
              type is a character string. The value of this  parameter  deter-
              mines  the  type of background. The possible values are: "globe"
              -- continental  outlines  "usa"  --  USA  and  state  boundaries
              "cglobe"  --  continental  outlines  and countries "usaglobe" --
              USA, state boundaries and continental outlines


       minlong (PLFLT, input)
              The value of the longitude on the left side of  the  plot.   The
              value of minlong must be less than the value of maxlong, and the
              quantity maxlong-minlong must be less than or equal to 360.

       maxlong (PLFLT, input)
              The value of the longitude on the right side of the plot.

       minlat (PLFLT, input)
              The minimum latitude to be plotted on the background.   One  can
              always  use  -90.0 as the boundary outside the plot window  will
              be automatically  eliminated.   However,  the  program  will  be
              faster if one can reduce the size of the background plotted.

       maxlat (PLFLT, input)
              The maximum latitudes to be plotted on the background.   One can
              always use 90.0 as the boundary outside the plot window  will be
              automatically eliminated.
