PLGCOL0(3plplot)

💅 PLGCOL0 💅

okay so real talk, bestie — this is a page straight out of the PLplot API manual, and honestly? she's a little legend. it's giving "small function, big main character energy." anyway let's get into it ✨

---

🌸 NAME 🌸

plgcol0 — returns 8-bit RGB values for a given color index from cmap0. periodt. 🎀

---

✨ SYNOPSIS ✨

plgcol0(icol0, r, g, b)

---

🦋 DESCRIPTION 🦋

so what she does is: she takes a color from cmap0 (check the PLplot documentation for the whole lore on that, iykyk) and hands you back its 8-bit RGB values, i.e. the 0-255 range. iconic behavior honestly.

but listen — if you pass her an invalid color id, the values come back negative. not a glow-up, just a warning sign. 💀

Redacted form: plgcol0(icol0, r, g, b)

fr fr, this function shows up in example 2 — so if you're out here wondering "where would I even see this in the wild," that's your answer, bestie. 🫶

💖 ARGUMENTS 💖

• icol0 (PLINT(3plplot), input) — the index of the cmap0 color you're obsessed with rn. she's the input, she's the moment. 👑
• r (PLINT_NC_SCALAR(3plplot), output) — here's where the 8-bit red value gets returned to you. you don't set it, she sets it. slay.
• g (PLINT_NC_SCALAR(3plplot), output) — same deal but green: the 8-bit green value comes back through this one. 💚
• b (PLINT_NC_SCALAR(3plplot), output) — and finally blue, the 8-bit blue value, returned right into here. trio complete, no cap. 💙
