NAME

6       DPLINE - Draws a straight-line segment between two points in the user
7       coordinate system.
8

SYNOPSIS

10       CALL DPLINE (XCP1,YCP1,XCP2,YCP2)
11

C-BINDING SYNOPSIS

13       #include <ncarg/ncargC.h>
14
15       void c_dpline (float xcp1, float ycp1, float xcp2, float ycp2);
16

DESCRIPTION

18       XCP1        (an input expression of type REAL) specifies the X
19                   coordinate of a point at the beginning of the straight-line
20                   segment.
21
22       YCP1        (an input expression of type REAL) specifies the Y
23                   coordinate of a point at the beginning of the straight-line
24                   segment.
25
26       XCP2        (an input expression of type REAL) specifies the X
27                   coordinate of a point at the end of the straight-line
28                   segment.
29
30       YCP2        (an input expression of type REAL) specifies the Y
31                   coordinate of a point at the end of the straight-line
32                   segment.
33

C-BINDING DESCRIPTION

35       The C-binding argument descriptions are the same as the FORTRAN
36       argument descriptions.
37

USAGE

39       DPLINE maps the input coordinates to the fractional system and then
40       passes them on to DPDRAW.  Even is smoothing is turned on, no smoothing
41       is done by a call to DPLINE.
42

EXAMPLES

44       Use the ncargex command to see the following relevant examples: tdshpk.
45

ACCESS

47       To use DPLINE or c_dpline, load the NCAR Graphics libraries ncarg,
48       ncarg_gks, and ncarg_c, preferably in that order.
