STRUCT PIXEL_YUV_U16(9)

✨ struct pixel_yuv_u16(9) ✨

okay so bestie, welcome to Kernel API Manual — today's main character is a little struct from the kernel world and honestly? she's serving 💅

🌸 NAME 🌸

struct pixel_yuv_u16 — the internal representation of a pixel color. that's it, that's her whole job. no cap, she just holds a color on the inside 🎀

🦋 SYNOPSIS 🦋

struct pixel_yuv_u16 {
    u16 y, u, v;
 };

look at that. three u16s, chillin' in a struct, living their best lives together 🫶

💖 Members 💖

• y — the luma value, stored in 16 bits, without padding, using machine endianness. she's the brightness baddie of the trio ⭐
• u — the blue difference chroma value, stored in 16 bits, without padding, using machine endianness. blue chroma said "i'm the moment" 💙
• v — the red difference chroma value, stored in 16 bits, without padding, using machine endianness. red chroma, aka the other half of the chroma duo, also iconic 🔥

ngl the "without padding, using machine endianness" part applies to literally all three of them — so don't go assuming anything about byte layout beyond that, bestie. fr fr.
