  • Method Details

    • run

      void run(PaintFuncs funcs, @Nullable MemorySegment paintData, Codepoint glyph, Font font)

      A virtual method for the hb_paint_funcs_t to clip subsequent paint calls to the outline of a glyph.

      The coordinates of the glyph outline are expected in the current font scale (ie. the results of calling hb_font_draw_glyph() with font). The outline is transformed by the current transform.

      This clip is applied in addition to the current clip, and remains in effect until a matching call to the hb_paint_funcs_pop_clip_func_t vfunc.

      Parameters:
      funcs - paint functions object
      paintData - The data accompanying the paint functions in hb_font_paint_glyph()
      glyph - the glyph ID
      font - the font

    • upcall

      default void upcall(MemorySegment funcs, MemorySegment paintData, int glyph, MemorySegment font, MemorySegment userData)
      The upcall method is called from native code. The parameters are marshaled and run(PaintFuncs, MemorySegment, Codepoint, Font) is executed.

    • toCallback

      default MemorySegment toCallback(Arena arena)
      Creates a native function pointer to the upcall(MemorySegment, MemorySegment, int, MemorySegment, MemorySegment) method.
      Specified by:
      toCallback in interface FunctionPointer
      Parameters:
      arena - the arena in which the function pointer is allocated
      Returns:
      the native function pointer
