    • invoke

      void invoke(long font, long font_data, int count, long first_glyph, int glyph_stride, long first_advance, int advance_stride, long user_data)
      A virtual method for the hb_font_funcs_t of an hb_font_t object.

      This method should retrieve the advances for a sequence of glyphs.

      Parameters:
      font - hb_font_t to work upon
      font_data - font user data pointer
      count - the number of glyph IDs in the sequence queried
      first_glyph - the first glyph ID to query
      glyph_stride - the stride between successive glyph IDs
      first_advance - the first advance retrieved
      advance_stride - the stride between successive advances
      user_data - user data pointer passed by the caller
