NAME

       TDPRPA - Given the parallelogram coordinates of a point, get the coordinates of its
       projection in the projection plane.  This routine is essentially the inverse of the
       routine TDPRPI.

SYNOPSIS

       CALL TDPRPA (XIPA, YIPA, XI2D, YI2D)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

       void c_tdprpa(float xipa, float yipa, float *xi2d, float *yi2d)

DESCRIPTION

       The arguments of TDPRPA are as follows:

       XIPA and YIPA
               (input expressions of type REAL) - the parallelogram coordinates of a point.  (The
               parallelogram is as defined by a prior call to TDPARA.)

       XI2D and YI2D
               (output variables of type REAL) - the coordinates of the projection of the point
               in the projection plane.

C-BINDING DESCRIPTION

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

ACCESS

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