exrgbhsv(3)

💖 exrgbhsv — RGB <-> HSV color space conversions 💖

okay bestie, welcome to the Allegro manual page for exrgbhsv(3), an example from the Allegro game programming library. it's giving color theory but make it a whole demo program, and honestly? we're obsessed. 🎀

✨ SYNOPSIS ✨

#include <allegro.h>

Example exrgbhsv

like that's it, that's the whole vibe. a lil include and a whole example program. iconic. 🦋

🌈 DESCRIPTION 🌈

so the tea is: this program shows you how to convert colors between the different color-space representations. rgb to hsv, hsv to rgb, the whole glow-up pipeline. 💅

here's the layout tour, no cap:

• the central area of the screen will display the current color. main character of the screen fr.
• in the top left corner of the screen, three sliders let you modify the red, green and blue value of the color. classic RGB girlies rise. 🍓
• in the bottom right corner of the screen, three sliders let you modify the hue, saturation and value of the color. hsv besties, we see you. 👑

and the color bars beneath the sliders? they show what the resulting color will look like when the slider is dragged to that position. so you get a lil preview of your future color before you commit. the way that's actually so thoughtful. 😭✨

additionally, this example also shows how to "inherit" the behaviour of a GUI object and extend it, here used to create the sliders. yes bestie, we're doing object inheritance, in a demo, for sliders. it's giving academic but cute. 🎓💖

💀 heads up bestie: this page is an example, not a function you call. go read rgb_to_hsv(3) and hsv_to_rgb(3) if you actually want the conversions themselves. iykyk.

Allegro version 4.4.3 — mwah, that's the version and the whole source of this lil page, periodt. 🫶✨ go make something gorgeous with it bestie, you got this 💖🌈🎀
