NAME

       fcft_rasterize_grapheme_utf32 - rasterize glyph(s) for a  grapheme cluster

SYNOPSIS

       #include <fcft/fcft.h>

       const struct fcft_grapheme *fcft_rasterize_grapheme_utf32(
           struct fcft_font *font, size_t len, const uint32_t grapheme_cluster[static len], enum fcft_subpixel
           subpixel);

DESCRIPTION

       fcft_rasterize_grapheme_utf32() rasterizes the grapheme cluster cluster using the primary font, or one of
       the fallback fonts, in font.

       Each cluster element is an UTF-32 encoded Unicode codepoint.

       The fonts are searched for all codepoints in the grapheme cluster, starting with the primary font and
       then the custom fallback fonts, and finally the FontConfig provided fallback fonts.

       subpixel allows you to specify which subpixel mode to use. See fcft_rasterize_char_utf32() for details.

RETURN VALUE

       On error, NULL is returned.

       On success, a pointer to a rasterized grapheme is returned. The grapheme is cached in fcft, making
       subsequent calls with the same arguments very fast (i.e. there is no need for programs to cache glyphs by
       themselves).

       The grapheme object is managed by font. There is no need to explicitly free it; it is freed when font is
       destroyed (with fcft_destroy()).

           struct fcft_grapheme {
               int cols;

               size_t count;
               const struct fcft_glyph **glyphs;
           };

       cols is the number of "columns" the glyph occupies (effectively, wcswidth(cluster)).

       glyphs is an array of count rasterized glyphs. See fcft_rasterize_char_utf32() for a description of
       struct fcft_glyph.
