NAME

       DPFRST - Specifies the first point in a sequence of points, in the user coordinate system,
       defining a curve to be drawn.

SYNOPSIS

       CALL DPFRST (XCPU,YCPU)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_dpfrst (float xcpu, float ycpu);

DESCRIPTION

       XCPU        (an input expression of type REAL) specifies the X coordinate of a point, in
                   the user coordinate system.

       YCPU        (an input expression of type REAL) specifies the Y coordinate of a point, in
                   the user coordinate system.

C-BINDING DESCRIPTION

       The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

USAGE

       Call DPFRST to do a "pen-up" move to the first of a sequence of points defining a curve.
       Call DPVECT to do "pen-down" moves to each of the other points in the sequence and then
       call DPLAST to finish drawing the curve and flush the buffers.

       DPFRST maps the input coordinates to the fractional coordinate system and then does a
       "pen-up" call to either DPDRAW (if smoothing is turned off) or to DPSMTH (if smoothing is
       turned on) with those coordinates.

EXAMPLES

       Use the ncargex command to see the following relevant examples: tdshpk.

ACCESS

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