NAME

       SFSETP - Defines a new dot pattern.

SYNOPSIS

       CALL SFSETP (IDP)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_sfsetp (int idp[8][8])

DESCRIPTION

       IDP         (an input array of type INTEGER, dimensioned 8x8) contains 0s and 1s
                   specifying the dot pattern to be transferred to the internal array LDP for use
                   by SFWRLD and SFNORM. When dot fill is selected, each fill line is drawn using
                   dots the same distance apart along the line as the lines are from each other.
                   The dots thus fall at the intersection points of a square grid.  Each dot is
                   associated with a particular element of LDP. If that element is a 1, the dot
                   is drawn; if it is a 0, the dot is not drawn. The association is done in such
                   a way as to replicate the pattern specified by LDP across the entire filled
                   area.

                   If the fill angle is 0 (the default), then incrementing the first subscript of
                   LDP corresponds to a horizontal motion across the plot from left to right and
                   incrementing the second subscript of LDP corresponds to a vertical motion
                   across the plot from top to bottom. This allows the contents of IDP to be
                   declared in a DATA statement which creates a "picture" of the pattern. For
                   example, the FORTRAN statements

                        DIMENSION IDP(8,8)
                        ...
                        DATA IDP / 0,0,0,0,0,0,0,0,
                       +           0,1,1,1,1,1,1,0,
                       +           0,1,0,0,0,0,0,1,
                       +           0,1,0,0,0,0,0,1,
                       +           0,1,1,1,1,1,1,0,
                       +           0,1,0,0,0,1,0,0,
                       +           0,1,0,0,0,0,1,0,
                       +           0,1,0,0,0,0,0,1/

                   creates the letter "R", with the correct orientation.

                   The contents of the array IDP are transferred to the internal array LDP. The
                   new dot pattern is used until a subsequent call to SFSETP changes the contents
                   of LDP again.

                   The default dot pattern consists of all 1s.

C-BINDING DESCRIPTION

       The C-binding argument description is the same as the FORTRAN argument description.

USAGE

       This routine allows you to set the current value of Softfill's dot pattern. For a
       description of Softfill's dot pattern parameter, see the softfill_params man page.

EXAMPLES

       Use the ncargex command to see the following relevant examples: sfex01, tsoftf.

ACCESS

       To use SFSETP or c_sfsetp, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c,
       preferably in that order.
