QwtAlphaColorMap(3)

💖 NAME 💖

QwtAlphaColorMap — okay bestie, this is a class from the Qwt User's Guide and the original manpage doesn't give it a one-liner description, so the name is literally just… the name. The real tea comes further down. 🫶

🌸 Additional Inherited Members 🌸

This section exists but the original lists nothing inside it. Empty. Void. A whole vibe of absence. 🙈 The inherited stuff from QwtColorMap is just implied, not spelled out here.

🦋 Detailed Description 🦋

QwtAlphaColorMap variies the alpha value of a color. (Yes, "variies" — that's the original wording, we don't edit, we respect the lore. 😭)

So like… the hue stays, the transparency does the talking. Iconic behaviour, honestly. ✨
