PLGCOLBG(3plplot)

💅 PLGCOLBG 💅

okay so this is a page from the PLplot API manual (that's the manual name, bestie, we're just folding it in here so it doesn't get lonely at the top) 🫶

✨ NAME ✨

plgcolbg — it hands you back the background color, which is cmap0[0], as an 8-bit RGB value. that's it, that's the whole job, and it does it flawlessly 👑

✨ SYNOPSIS ✨

plgcolbg(r, g, b)

✨ DESCRIPTION ✨

So like… plgcolbg returns the background color, aka cmap0[0], expressed as an 8-bit RGB value. three little numbers, one big vibe 🌈

Redacted form: plgcolbg(r, g, b) — yes bestie, same thing, it's just the short version, nothing shady going on 🙈

Also! This function shows up in example 31, so if you wanna see it living its best life in the wild, go look there 👀

🎀 ARGUMENTS 🎀

• r (PLINT_NC_SCALAR(3plplot), output) — the returned red intensity, and it's a number from 0 to 255. literally a whole 8 bits of red, slay 🔥
• g (PLINT_NC_SCALAR(3plplot), output) — the returned green intensity, also in the range from 0 to 255. green flag behavior fr fr 💚
• b (PLINT_NC_SCALAR(3plplot), output) — the returned blue intensity, range 0 to 255 as well. blue era, we love to see it 💙

ngl, all three of these are output args, so the function is the one filling them in for you — you're not passing in your own values, you're receiving gifts 🎁
