TDPRPA(3NCARG)

✨ NAME ✨

ok so bestie, TDPRPA is a little icon in the NCAR Graphics universe (it lives in section 3NCARG, iykyk) 💅

Here's the tea: you hand it the parallelogram coordinates of a point, and it hands you back the coordinates of that point's projection in the projection plane. It's basically the inverse of its bestie, TDPRPI — they're giving very much "we complete each other" energy fr fr 🫶

🌸 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 literally as follows, no cap:

• XIPA and YIPA — (input expressions of type REAL) these are the parallelogram coordinates of a point. Now listen 👀 — the parallelogram in question is the one that was set up by a prior call to TDPARA. So don't come in here expecting it to just know, bestie, you gotta call TDPARA first or it's giving nothing. ✨
• XI2D and YI2D — (output variables of type REAL) the coordinates of the projection of that point in the projection plane. That's it, that's the whole glow-up. 🎀

🌈 C-BINDING DESCRIPTION 🌈

The C-binding argument descriptions are the exact same as the FORTRAN argument descriptions. Same vibe, different language, periodt. 💜

👑 ACCESS 👑

To use TDPRPA or c_tdprpa, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c — preferably in that order. Like, order matters, don't be chaotic about it. 🧚
