PLSCOLBGA(3plplot)

💅 PLSCOLBGA — the plplot glow-up for your background

okay bestie, so this is a page from the PLplot API manual set — the whole PLplot API family, and this specific icon is PLSCOLBGA(3plplot). Buckle up, it's short and sweet. 🎀

---

✨ SYNOPSIS ✨

plscolbga(r, g, b, alpha)

That's the whole vibe check. Four args, one background color, zero drama. 🦋

---

🌸 DESCRIPTION 🌸

So what does it do? It sets the background color — which is, and I cannot stress this enough, color 0 in cmap0 — using an 8-bit RGB value plus a PLFLT alpha transparency value (peep the PLplot documentation for the deeper lore). 👑

Lowkey iconic behavior. You're literally picking the canvas energy for everything else.

And like... this function is used in example 31. So if you wanna see it living its best life in the wild, that's where it's at. 🔥

fr fr, it's a small function but it's giving main character energy for your whole plot background.

🧚 ARGUMENTS 🧚

• r (PLINT(3plplot), input) — unsigned 8-bit integer (0-255) representing the degree of red in the color. 🌹
• g (PLINT(3plplot), input) — unsigned 8-bit integer (0-255) representing the degree of green in the color. 🍓 (green strawberry? sure bestie, it's a vibe)
• b (PLINT(3plplot), input) — unsigned 8-bit integer (0-255) representing the degree of blue in the color. 💙
• alpha (PLFLT(3plplot), input) — the value of the alpha transparency, in the range (0.0-1.0). Translucent queen behavior. ✨🙈
