font_glyph_rotate_180(9)

✨ font_glyph_rotate_180 💅

okay bestie, welcome to font_glyph_rotate_180(9) from the Kernel API Manual — yes literally the same name, she's iconic and she's not changing it for anyone 🎀 this is the function that flips your glyph all the way around like it just heard the best gossip and needs to look 😭

---

🌸 NAME 🌸

font_glyph_rotate_180 — Rotate a glyph pattern by 180° 🦋

no cap, that's the whole gig: 180 degrees, half a full spin, the full glow-up in reverse 🌈

---

🎀 SYNOPSIS 🎀

void font_glyph_rotate_180 (const unsigned char *glyph , unsigned int
width , unsigned int height , unsigned char *out );

look at her go, she takes absolutely zero shortcuts and returns exactly nothing (it's void, she's mysterious like that ✨). Keep the const on glyph — she's not gonna touch your input, periodt.

---

👑 ARGUMENTS 👑

• glyph — The glyph to rotate 💖 that's your input bitmap, the main character.
• width — The glyph width in bits per scanline 🧚 yes, bits, not bytes, read it again bestie.
• height — The number of scanlines in the glyph 🌸 that's the vertical situation, count them all.
• out — The rotated glyph bitmap ⭐ this is where the 180°-flipped result lands.

---

🔥 DESCRIPTION 🔥

so here's the vibe check: width and height describe the input glyph you passed in as glyph. they're the dimensions of what goes in, not what comes out 👀 (the shape doesn't change size when you spin it, it's giving same-size-different-orientation energy, but fr fr just remember those params belong to glyph).

and the important part, do not skip this:

The caller has to provide the output buffer out of sufficient size to hold the rotated glyph. like, you bring the buffer, she just writes into it 💀 nobody's allocating for you, this is not a charity, mwah 💅
