ncl_tdprpa - Man Page
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.
CALL TDPRPA (XIPA, YIPA, XI2D, YI2D)
void c_tdprpa(float xipa, float yipa, float *xi2d, float *yi2d)
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.
The C-binding argument descriptions are the same as the FORTRAN argument descriptions.
To use TDPRPA or c_tdprpa, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
