hb_ot_shape_glyphs_closure ()

void
hb_ot_shape_glyphs_closure (hb_font_t *font,
                            hb_buffer_t *buffer,
                            const hb_feature_t *features,
                            unsigned int num_features,
                            hb_set_t *glyphs);

Computes the transitive closure of glyphs needed for a specified input buffer under the given font and feature list. The closure is computed as a set, not as a list.

Since: 0.9.2

HB_OT_SHAPE_BUFFER_FORMAT_SERIAL

#define HB_OT_SHAPE_BUFFER_FORMAT_SERIAL 1

The serial number of the current internal buffer format.

The serial number will increase when internal hb_glyph_info_t and hb_glyph_position_t members change their format.
