NAME

TTF_GetGlyphMetrics - Query the metrics (dimensions) of a font’s glyph for a UNICODE codepoint.

HEADER FILE

Defined in SDL3_ttf/SDL_ttf.h

SYNOPSIS

#include "SDL3_ttf/SDL_ttf.h"

bool TTF_GetGlyphMetrics(TTF_Font *font, Uint32 ch, int *minx, int *maxx, int *miny, int *maxy, int *advance);

DESCRIPTION

To understand what these metrics mean, here is a useful link:

FUNCTION PARAMETERS

	font		the font to query.
	ch		the codepoint to check.
	minx		a pointer filled in with the minimum x coordinate of the glyph from the left edge of its bounding box. This value may be negative.
	maxx		a pointer filled in with the maximum x coordinate of the glyph from the left edge of its bounding box.
	miny		a pointer filled in with the minimum y coordinate of the glyph from the bottom edge of its bounding box. This value may be negative.
	maxy		a pointer filled in with the maximum y coordinate of the glyph from the bottom edge of its bounding box.

advance

a pointer filled in with the distance to the next glyph from the left edge of this glyph’s bounding box.

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.
