✨ TTF_GetGlyphImageForIndex ✨

okay bestie, welcome to the SDL_ttf3 FUNCTIONS corner of the group chat 💖 this one lives in the manual as TTF_GetGlyphImageForIndex(3) and it is literally the "gimme the actual pixels for this glyph index" function. no cap.

🎀 NAME 🎀

TTF_GetGlyphImageForIndex — get the pixel image for a character index. that's it, that's the whole vibe 🦋

📁 HEADER FILE 📁

Defined in SDL3_ttf/SDL_ttf.h — yes queen, that's where it lives 🫶

🌸 SYNOPSIS 🌸

#include "SDL3_ttf/SDL_ttf.h"

SDL_Surface * TTF_GetGlyphImageForIndex(TTF_Font *font, Uint32 glyph_index, TTF_ImageType *image_type);

look at that signature. SDL_Surface * on the left, three args on the right. iconic behavior honestly 👑

💅 DESCRIPTION 💅

so the way this is useful is for text engine implementations — like, if you're building a whole text renderer yourself and you're the main character of the layout algorithm. those implementations can call this with the glyph_index in a TTF_CopyOperation. that's the whole deal, fr fr. 🧚

🔥 FUNCTION PARAMETERS 🔥

  • font — the font to query. that's your font bestie, hand it over 💜
  • glyph_index — the index of the glyph to return. the actual number of the glyph you want, not the character itself, okay? important distinction, iykyk.
  • image_type — a pointer filled in with the glyph image type, and lowkey it may be NULL if you don't care about that info. she's optional, we respect that 🙈

⭐ RETURN VALUE ⭐

Returns an SDL_Surface containing the glyph. 🎀

or NULL on failure — and in that case, bestie, call SDL_GetError() for more information. don't just sit there wondering, the error string is right there 😭

🦋 THREAD SAFETY 🦋

This function should be called on the thread that created the font. periodt. don't be passing your font across threads like it's a group chat screenshot, it's not built for that 💀

🌈 AVAILABILITY 🌈

This function is available since SDL_ttf 3.0.0. so if you're on something older, it's giving "not yet, babe" 🍓

and that's the page!! 💖 go forth and render glyphs, you absolute legend. this whole thing came to you from SDL_ttf 3.2.2, in the SDL_ttf manual, filed under TTF_GetGlyphImageForIndex(3) — mwah, love u, bye!! ✨👑💅
