NAME

6       TDLNPA - Given the coordinates of two points in the reference
7       parallelogram, draw the projection of the line joining them.
8

SYNOPSIS

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

C-BINDING SYNOPSIS

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

DESCRIPTION

18       The arguments of TDLNPA are as follows:
19
20       XCP1 and YCP1
21               (input expressions of type REAL) - the parallelogram
22               coordinates of a point in the reference parallelogram (as
23               defined by the last call to TDPARA).
24
25       XCP2 and YCP2
26               (input expressions of type REAL) - the parallelogram
27               coordinates of another point in the reference parallelogram.
28

C-BINDING DESCRIPTION

30       The C-binding argument descriptions are the same as the FORTRAN
31       argument descriptions.
32

ACCESS

34       To use TDLNPA or c_tdlnpa, load the NCAR Graphics libraries ncarg,
35       ncarg_gks, and ncarg_c, preferably in that order.
