ttfSetFontSize function

bool ttfSetFontSize(
  1. Pointer<TtfFont> font,
  2. double ptsize
)

Set a font's size dynamically.

This updates any TTF_Text objects using this font, and clears already-generated glyphs, if any, from the cache.

\param font the font to resize. \param ptsize the new point size. \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.
