GCA(3NCARG)

✨ GCA (Cell Array) — the NCAR Graphics glow-up for rectangles 💅

okay bestie, welcome to the NCAR Graphics manual, page GCA(3NCARG). this one's a whole vibe: you hand it a rectangle, it chops that rectangle into a grid of little cells, and every single cell gets its own color. it's giving mosaic energy. 🎀

---

🌸 NAME 🌸

GCA (Cell array) — draws a cell array starting with a rectangle specified by two corner points; this initial rectangle is subdivided into subrectangles by specifying an arbitrary number of divisions in the X and Y directions; each subrectangle (or cell) is assigned a color and drawn with that color. 🦋

---

🌈 SYNOPSIS 🌈

CALL GCA (XP1, YP1, XP2, YP2, NXCLR, NYCLR, IXCLR, IYCLR, NXDO, NYDO,
CLRIA)

---

✨ C-BINDING SYNOPSIS ✨

#include <ncarg/gks.h>

void gcell_array(const Grect *rect, const Gpat_rep *colr_array);

---

💖 DESCRIPTION 💖

okay so here's every single argument, no skipping, we're being thorough because that's the main character thing to do:

• XP1 — (Real, Input) — X world coordinate of point 1. 📍
• YP1 — (Real, Input) — Y world coordinate of point 1. 📍
• XP2 — (Real, Input) — X world coordinate of point 2. 📍
• YP2 — (Real, Input) — Y world coordinate of point 2. 📍
• NXCLR — (Integer, Input) — X dimension of the color index array CLRIA. 🧮
• NYCLR — (Integer, Input) — Y dimension of the color index array CLRIA. 🧮
• IXCLR — (Integer, Input) — The index of the starting column in index array CLRIA. 🎯
• IYCLR — (Integer, Input) — The index of the starting row in index array CLRIA. 🎯
• NXDO — (Integer, Input) — Number of cell elements to draw in the X dimension. 🔢
• NYDO — (Integer, Input) — Number of cell elements to draw in the Y dimension. 🔢
• CLRIA — (Integer array, Input) — An array of color indices dimensioned NXCLR x NYCLR which is used to determine the color of each cell drawn. 🎨

🫶 USAGE 🫶

Points 1 and 2 must be diagonally opposite corner points of a rectangle to be divided into NXDO cells in the X dimension and NYDO cells in the Y dimension. like, corners on opposite ends of the diagonal, not neighbors. iykyk. 💅

👑 ACCESS 👑

To use GKS routines, load the NCAR GKS-0A library ncarg_gks. that's it, that's the whole prerequisite. 🧚

ngl bestie, this page is UNIX-flavored and dates all the way back to March 1993 — vintage, iconic, still slaying. that's GCA(3NCARG) fr fr, catch you in the next manpage. 🍓💀✨
