NAME

6       DPFRST - Specifies the first point in a sequence of points, in the user
7       coordinate system, defining a curve to be drawn.
8

SYNOPSIS

10       CALL DPFRST (XCPU,YCPU)
11

C-BINDING SYNOPSIS

13       #include <ncarg/ncargC.h>
14
15       void c_dpfrst (float xcpu, float ycpu);
16

DESCRIPTION

18       XCPU        (an input expression of type REAL) specifies the X
19                   coordinate of a point, in the user coordinate system.
20
21       YCPU        (an input expression of type REAL) specifies the Y
22                   coordinate of a point, in the user coordinate system.
23

C-BINDING DESCRIPTION

25       The C-binding argument descriptions are the same as the FORTRAN
26       argument descriptions.
27

USAGE

29       Call DPFRST to do a "pen-up" move to the first of a sequence of points
30       defining a curve.  Call DPVECT to do "pen-down" moves to each of the
31       other points in the sequence and then call DPLAST to finish drawing the
32       curve and flush the buffers.
33
34       DPFRST maps the input coordinates to the fractional coordinate system
35       and then does a "pen-up" call to either DPDRAW (if smoothing is turned
36       off) or to DPSMTH (if smoothing is turned on) with those coordinates.
37

EXAMPLES

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

ACCESS

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