PLSPAL1(3plplot)

💅 PLSPAL1 — like, the whole vibe check on plspal1(3plplot)

okay so bestie, welcome to the PLplot API manual page for plspal1, and yes we are absolutely going to get into it 🎀

✨ NAME ✨

plspal1 — sets the cmap1 palette using the cmap1*.pal format file you point at 🦋

🌸 SYNOPSIS 🌸

plspal1(filename, interpolate)

💖 DESCRIPTION 💖

So basically: this one sets the cmap1 palette using the cmap1*.pal format file you specify. That's the whole job. She's focused, she's iconic, she does one thing 👑

Redacted form, since you know the docs love a redacted form: plspal1(filename, interpolate)

And fun fact — this function is used in example 16. periodt 💅

🧚 ARGUMENTS 🧚

• filename (PLCHAR_VECTOR(3plplot), input) — an ascii character string holding the name of the cmap1*.pal file. And listen, if this string is empty? It just uses the default cmap1*.pal file. no stress, she's got a fallback 🫶
• interpolate (PLBOOL(3plplot), input) — okay this one's the main character, lemme explain 🎀

If this parameter is true, the columns in the cmap1*.pal file containing the intensity index, r, g, b, alpha and alt_hue_path get used to set the cmap1 palette, with a call to plscmap1la(3plplot). (And heads up — the cmap1*.pal header contains a flag that controls whether the r, g, b data sent to plscmap1la(3plplot) gets interpreted as HLS or RGB. iykyk 🌈)

If this parameter is false, then the intensity index and alt_hue_path columns are, like, completely ignored 🙈 and instead the r, g, b columns (interpreted as RGB) and the alpha column of the cmap1*.pal file get used to set the cmap1 palette directly with a call to plscmap1a(3plplot). two different paths, both valid, we respect both 💜
