3.2.4 TTF_OpenFontIndexRW
TTF_Font *TTF_OpenFontIndexRW(SDL_RWops *src, int freesrc, int ptsize, long index)
- src
- The source SDL_RWops as a pointer. The font is loaded from this.
- freesrc
- A non-zero value means it will automatically close and free the src for you after it finishes using the src, even if a noncritical error occured.
- ptsize
- Point size (based on 72DPI) to load font as.
This basically translates to pixel height.
- index
- Choose a font face from a file containing multiple font faces.
The first face is always index 0.
Load src, face index, for use as a font, at ptsize size.
This can load TTF and FON formats.
Using SDL_RWops
is not covered here, but they enable you to load from almost any source.
NOTE: src is not checked for NULL, so be careful.
Returns: a pointer to the font as a TTF_Font
. NULL is returned on errors.
| // load font.ttf, face 0, at size 16 into font
TTF_Font *font;
font=TTF_OpenFontRW(SDL_RWFromFile("font.ttf"), 1, 16, 0);
if(!font) {
printf("TTF_OpenFontIndexRW: %s\n", TTF_GetError());
// handle error
}

Note that this is unsafe because we don't check the validity of the SDL_RWFromFile
's returned pointer.
