TDPRPI(3) Given a point in the projection plane, retrieve the parallelogram

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.
