PLGCOLBGA(3plplot)

🎀 PLGCOLBGA — plgcolbga(3plplot) 🎀

okay bestie, so this is a page from the PLplot API and honestly? it's a little guy but it's an icon. let's get into it 💅

---

✨ NAME ✨

plgcolbga — Returns the background color (cmap0[0]) by 8-bit RGB value and PLFLT alpha transparency value 🎨

---

✨ SYNOPSIS ✨

plgcolbga(r, g, b, alpha)

like, that's it. four little arguments. slay.

---

✨ DESCRIPTION ✨

so basically 💖 — this one hands you back the background color, which lives at cmap0[0], served up as an 8-bit RGB value plus a PLFLT alpha transparency value. two things at once, it's giving overachiever, we love her.

that's the whole vibe. no cap.

ngl, this function is used in example 31. that's the lore. 🫶

---

✨ ARGUMENTS ✨

• r (PLINT_NC_SCALAR(3plplot), output) — the returned value of the red intensity, and the range is from 0 to 255. red flag but make it literal 🌹
• g (PLINT_NC_SCALAR(3plplot), output) — the returned value of the green intensity, also ranging from 0 to 255. green flag behavior fr fr 🍓
• b (PLINT_NC_SCALAR(3plplot), output) — the returned value of the blue intensity, same deal, from 0 to 255. blue era 💙
• alpha (PLFLT_NC_SCALAR(3plplot), output) — the returned value of the alpha transparency, in the range (0.0-1.0). so like, fully see-through to fully solid, pick your fighter ✨

heads up: r, g, b, and alpha are all output arguments, so the function is filling them in, not you, main character energy only in one direction 💀
