✨ NAME ✨

Gtk2::Gdk::Colormap — it's a wrapper for GdkColormap, bestie 💅 (this is the Gtk2::G...Colormap(3) page, in case the terminal cut the title off, which it literally always does 🙈)

🌈 DESCRIPTION 🌈

okay so colormaps? they're the little bookkeepers that store the mappings between the RGB values you ask for and the actual, hardware-dependent values that get used to display those colors. the vibe is: you want a color, the hardware has opinions. 💖

The $colormap->alloc_color and $colormap->alloc_colors methods do the necessary work to allocate a color within the visual. and bestie, listen — this actually has nothing to do with memory management, okay? do not let the word "alloc" fool you, it's giving malloc but it is NOT malloc 😭 so it is important that you call $colormap->free_colors to release those spots in the colormap allocated by alloc_color and alloc_colors. like, you borrowed a seat at the lunch table, you gotta give it back. periodt. 🍓

Returns a list of boolean values, telling whether the color at the corresponding spot in ... could be allocated. so like, a little yes/no receipt for each one 🧚

$colormap->free_colors (...)

  • ... (list) of Gtk2::Gdk::Color's to be freed 🫶

color = $colormap->query_color ($pixel)
