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.
