TDLNPA(3NCARG) NCAR GRAPHICS TDLNPA(3NCARG)

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

CALL TDLNPA (XCP1, YCP1, XCP2, YCP2)

#include <ncarg/ncargC.h>

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

The arguments of TDLNPA are as follows:

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

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

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