ncl_tdlnpa man page

TDLNPA — Given the coordinates of two points in the reference parallelogram, draw the projection of the line joining them.

Synopsis

CALL TDLNPA (XCP1, YCP1, XCP2, YCP2)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_tdlnpa(float xcp1, float ycp1, float xcp2, float ycp2)

Description

The arguments of TDLNPA are as follows:

XCP1 and YCP1
(input expressions of type REAL) - the parallelogram coordinates of a point in the reference parallelogram (as defined by the last call to TDPARA).
XCP2 and YCP2
(input expressions of type REAL) - the parallelogram coordinates of another point in the reference parallelogram.

C-Binding Description

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

Access

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