NAME

       TDPRPI - Given a point in the projection plane, retrieve the parallelogram coordinates of
       that point in the reference parallelogram (as defined by the last call to TDPARA) that
       projects into it.  This routine is essentially the inverse of the routine TDPRPA.

SYNOPSIS

       CALL TDPRPI (XI2D, YI2D, XIPA, YIPA)

C-BINDING SYNOPSIS

       #include <ncarg/ncargC.h>

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

DESCRIPTION

       The arguments of TDPRPI are as follows:

       XI2D and YI2D
               (input expressions of type REAL) - the coordinates of a point in the projection
               plane.

       XIPA and YIPA
               (output variables of type REAL) - the parallelogram coordinates of that point in
               the reference parallelogram that projects into (XI2D,YI2D).  (The parallelogram is
               as defined by a prior call to TDPARA.)

C-BINDING DESCRIPTION

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

ACCESS

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