TTF_GlyphMetrics32

Query the metrics (dimensions) of a font's 32-bit glyph.

Syntax

int TTF_GlyphMetrics32(TTF_Font *font, Uint32 ch,
                     int *minx, int *maxx,
                     int *miny, int *maxy, int *advance);

Function Parameters

font

the font to query.

ch

the character code to check.

Remarks

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

https://freetype.sourceforge.net/freetype2/docs/tutorial/step2.html

This is the same as TTF_GlyphMetrics(), but takes a 32-bit character instead of 16-bit, and thus can query a larger range. If you are sure you'll have an SDL_ttf that's version 2.0.18 or newer, there's no reason not to use this function exclusively.

Version

This function is available since SDL_ttf 2.0.18.
