TTF_GetGlyphMetrics

Query the metrics (dimensions) of a font's glyph for a UNICODE codepoint.

Header File

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

TTF_Font *	font	the font to query.
Uint32	ch	the codepoint to check.
int *	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.
int *	maxx	a pointer filled in with the maximum x coordinate of the glyph from the left edge of its bounding box.
int *	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.
int *	maxy	a pointer filled in with the maximum y coordinate of the glyph from the bottom edge of its bounding box.
int *	advance	a pointer filled in with the distance to the next glyph from the left edge of this glyph's bounding box.

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

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

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

This function is available since SDL_ttf 3.0.0.
