6 DPFRST - Specifies the first point in a sequence of points, in the user
7 coordinate system, defining a curve to be drawn.
8
10 CALL DPFRST (XCPU,YCPU)
11
13 #include <ncarg/ncargC.h>
14
15 void c_dpfrst (float xcpu, float ycpu);
16
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
25 The C-binding argument descriptions are the same as the FORTRAN
26 argument descriptions.
27
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
39 Use the ncargex command to see the following relevant examples: tdshpk.
40
42 To use DPFRST or c_dpfrst, load the NCAR Graphics libraries ncarg,
43 ncarg_gks, and ncarg_c, preferably in that order.
