TTF_GetGlyphMetrics3
Query the metrics (dimensions) of a font's glyph for a unicode codepoint.
Usage
#include "SDL3_ttf/SDL_ttf.h"
bool TTF_GetGlyphMetrics(TTF_Font *font, Uint32 ch, int *minx, int *maxx, int *miny, int *maxy, int *advance);

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.
