ttfSetFontDirection function ttf

bool ttfSetFontDirection(
  1. Pointer<TtfFont> font,
  2. int direction
)

Set the direction to be used for text shaping by a font.

This function only supports left-to-right text shaping if SDL_ttf was not built with HarfBuzz support.

This updates any TTF_Text objects using this font.

\param font the font to modify. \param direction the new direction for text to flow. \returns true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should be called on the thread that created the font.

\since This function is available since SDL_ttf 3.0.0.
