TTF_SetFontDirection(3)

💖 TTF_SetFontDirection(3) 💖

okay bestie, welcome to the SDL_ttf3 function club, today's guest of honour is TTF_SetFontDirection — she sets the direction that a font uses for text shaping. yes, like, which way the words go. iconic behaviour fr fr. 🦋

---

✨ NAME ✨

TTF_SetFontDirection — set the direction to be used for text shaping by a font.

---

🌸 HEADER FILE 🌸

she lives in SDL3_ttf/SDL_ttf.h, defined in SDL3_ttf/SDL_ttf.h. that's her address, don't lose it. 🎀

---

⭐ SYNOPSIS ⭐

#include "SDL3_ttf/SDL_ttf.h"

bool TTF_SetFontDirection(TTF_Font *font, TTF_Direction direction);

look at her. short. sweet. takes two things and returns a bool. main character energy honestly. 💅

---

💜 DESCRIPTION 💜

so here's the tea: this function only supports left-to-right text shaping if SDL_ttf was not built with HarfBuzz support. like, no HarfBuzz in your build? then LTR is all you're getting, that's the whole menu. no cap. 🫶

also — and this is the important bit — calling this updates any TTF_Text objects using this font. not just new ones. the existing ones. she goes back and updates her exes. 😭

---

🧚 FUNCTION PARAMETERS 🧚

• font — the font to modify. yes queen, this is the one you're changing.
• direction — the new direction for text to flow. the vibe check for which way the words travel.

🔥 RETURN VALUE 🔥

returns true on success or false on failure — and if it fails, bestie, go call SDL_GetError() for more info. she will tell you what went wrong, just ask her. 💀

---

🌈 THREAD SAFETY 🌈

please please please call this on the thread that created the font. that's the rule. respect the origin thread, she's the only one who can touch this font safely. 👑
