NAME

       plmapfill - Plot all or a subset of Shapefile data, filling the polygons

SYNOPSIS

       plmapfill(mapform, name, minx, maxx, miny, maxy, plotentries, nplotentries)

DESCRIPTION

       As   per   plmapline(3plplot),   however   the  items  are  filled  in  the  same  way  as
       plfill(3plplot).

       Redacted form: plmapfill(mapform, name, minx, maxx, miny, maxy, plotentries)

       This function is used in example 19.

ARGUMENTS

       mapform (PLMAPFORM_callback(3plplot), input)
              A user supplied function to transform the coordinates given in the shapefile into 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 corresponding 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.

       name (PLCHAR_VECTOR(3plplot), input)
              An  ascii  character  string  specifying  the file name of a set of Shapefile files
              without the file extension.

       minx (PLFLT(3plplot), input)
              The minimum x value to be plotted. This must be in the same units as  used  by  the
              Shapefile.  You  could use a very large negative number to plot everything, but you
              can improve performance by limiting the area drawn. The units must match  those  of
              the Shapefile projection, which may be for example longitude or distance. The value
              of minx must be less than the value of maxx.

       maxx (PLFLT(3plplot), input)
              The maximum x value to be plotted. You could  use  a  very  large  number  to  plot
              everything, but you can improve performance by limiting the area drawn.

       miny (PLFLT(3plplot), input)
              The  minimum  y  value to be plotted. This must be in the same units as used by the
              Shapefile. You could use a very large negative number to plot everything,  but  you
              can  improve  performance by limiting the area drawn. The units must match those of
              the Shapefile projection, which may be for example latitude or distance. The  value
              of miny must be less than the value of maxy.

       maxy (PLFLT(3plplot), input)
              The  maximum  y  value  to  be  plotted.  You could use a very large number to plot
              everything, but you can improve performance by limiting the area drawn.

       plotentries (PLINT_VECTOR(3plplot), input)
              A vector containing the zero-based indices of the Shapefile elements which will  be
              drawn. Setting plotentries to NULL will plot all elements of the Shapefile.

       nplotentries (PLINT(3plplot), input)
              The number of items in plotentries. Ignored if plotentries is NULL.
