TTF_SetFontOutline

Set a font's current outline.

Header File

Defined in <SDL3_ttf/SDL_ttf.h>

Syntax

bool TTF_SetFontOutline(TTF_Font *font, int outline);

Function Parameters

TTF_Font *	font	the font to set a new outline on.
int	outline	positive outline value, 0 to default.

Return Value

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

Remarks

This uses the font properties TTF_PROP_FONT_OUTLINE_LINE_CAP_NUMBER, TTF_PROP_FONT_OUTLINE_LINE_JOIN_NUMBER, and TTF_PROP_FONT_OUTLINE_MITER_LIMIT_NUMBER when setting the font outline.

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

Thread Safety

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