(This function is part of SDL_ttf, a separate library from SDL.)

TTF_OpenFontIO

Create a font from an SDL_IOStream, using a specified point size.

Header File

Syntax

TTF_Font * TTF_OpenFontIO(SDL_IOStream *src, bool closeio, float ptsize);

Function Parameters

SDL_IOStream *	src	an SDL_IOStream to provide a font file's data.
bool	closeio	true to close `src` when the font is closed, false to leave it open.
float	ptsize	point size to use for the newly-opened font.

Return Value

(TTF_Font *) Returns a valid TTF_Font, or NULL on failure; call SDL_GetError() for more information.

Remarks

Some .fon fonts will have several sizes embedded in the file, so the point size becomes the index of choosing which size. If the value is too high, the last indexed size will be the default.

If closeio is true, src will be automatically closed once the font is closed. Otherwise you should close src yourself after closing the font.

When done with the returned TTF_Font, use TTF_CloseFont() to dispose of it.

Thread Safety

It is safe to call this function from any thread.

Version

This function is available since SDL_ttf 3.0.0.
