      getCallInterface in interface org.lwjgl.system.CallbackI

    • callback

      default void callback(long ret, long args)
      Specified by:

    • invoke

      int invoke(long font, long font_data, int glyph, long x, long y, long user_data)
      A virtual method for the hb_font_funcs_t of an hb_font_t object.

      This method should retrieve the (X,Y) coordinates (in font units) of the origin for a glyph. Each coordinate must be returned in an hb_position_t output parameter.

      Return value: true if data found, false otherwise

      Parameters:
      font - hb_font_t to work upon
      font_data - font user data pointer
      glyph - the glyph ID to query
      x - the X coordinate of the origin
      y - the Y coordinate of the origin
      user_data - user data pointer passed by the caller
