NAME

       TTF_SetFontSDF - Enable Signed Distance Field rendering for a font.

HEADER FILE

       Defined in SDL3_ttf/SDL_ttf.h

SYNOPSIS

       #include "SDL3_ttf/SDL_ttf.h"

       bool TTF_SetFontSDF(TTF_Font *font, bool enabled);

DESCRIPTION

       SDF  is  a  technique  that  helps  fonts look sharp even when scaling and rotating, and requires special
       shader support for display.

       This works with Blended APIs, and generates the raw signed distance values in the alpha  channel  of  the
       resulting texture.

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

FUNCTION PARAMETERS

       font   the font to set SDF support on.

       enabled
              true to enable SDF, false to disable.

RETURN VALUE

       Returns true on success or false on failure; call SDL_GetError() for more information.

THREAD SAFETY

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

AVAILABILITY

       This function is available since SDL_ttf 3.0.0.
