GSVP(3NCARG)

💖 GSVP — set viewport, bestie edition 💖

okay so real talk: this is the NCAR Graphics manual page for GSVP (aka Set viewport), and she's a little bit of a "we don't really do this anymore" girlie, but we're gonna learn her anyway because knowing things is the whole vibe. 🎀

---

✨ NAME ✨

GSVP (Set viewport) — she establishes a rectangular subspace of normalized device coordinates space. 🦋

⚠️ ngl, calls to GSVP are discouraged with NCAR Graphics. Instead, use the SET subroutine, because SET also supports mirror imaging and log scaling of axes. periodt. 💅

---

🌸 SYNOPSIS 🌸

CALL GSVP (TRNUM, XMIN, XMAX, YMIN, YMAX)

---

🫶 C-BINDING SYNOPSIS 🫶

#include <ncarg/gks.h>

void gset_vp(Gint tran_num, const Glimit *vp_limits);

---

👑 DESCRIPTION 👑

the arguments, one by one, no skipping 🙈

• TRNUM (Integer, Input) — a normalization transformation number. The number of available transformations is implementation specific, iykyk. In the case of NCAR GKS-0A, two normalization transformations are provided:
  • 0 — selects the identity transformation, in which both the window and viewport have the range of 0. to 1. in both coordinate directions. This is the default normalization transformation for GKS. It is also fixed within GKS; that is, it is illegal to call GSVP with TRNUM = 0. 💀 like, don't even try it bestie.
  • 1 — a normalization transformation in which the viewport is defined by XMIN to XMAX and YMIN to YMAX.
• XMIN (Real, Input) — the left horizontal coordinate of the viewport. 🦋
• XMAX (Real, Input) — the right horizontal coordinate of the viewport. 0. ≤ XMIN < XMAX ≤ 1.
• YMIN (Real, Input) — the bottom vertical coordinate of the viewport. 🌱
• YMAX (Real, Input) — the top vertical coordinate of the viewport. 0. ≤ YMIN < YMAX ≤ 1.

the defaults, so you know what you get if you just vibe 🌈

Defaults:   TRNUM = 0, XMIN = 0.0, XMAX = 1.0, YMIN = 0.0, YMAX = 1.0

💜 ACCESS 💜

To use GKS routines, load the NCAR GKS-0A library ncarg_gks. literally just that. ✨
