TDPRPI(3NCARG)

okay so bestie 💖 welcome to TDPRPI(3NCARG), a page from the NCAR GRAPHICS manual. she's the inverse-projection girlie: you give her a point in the projection plane, she retrieves the parallelogram coordinates in the reference parallelogram that projects into it. no cap, it's giving TDPRPA's inverse. periodt. 💅

✨ 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 her like this:

CALL TDPRPI (XI2D, YI2D, XIPA, YIPA)

💅 C-BINDING SYNOPSIS 💅

C besties, include this:

#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. literally the 2D point, bestie.
• 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.) so like, she hands you back the parallelogram coords for that projection-plane point. ✨

🎀 C-BINDING DESCRIPTION 🎀

the C-binding argument descriptions are the same as the FORTRAN argument descriptions. same facts, C-coded, no cap. 💅

🔥 ACCESS 🔥

to use TDPRPI or c_tdprpi, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order. don't be chaotic, bestie. 💖
