  • Constructor Details

    • hb_glyph_extents_t

      public hb_glyph_extents_t(ByteBuffer container)
      Creates a hb_glyph_extents_t instance at the current position of the specified ByteBuffer container. Changes to the buffer's content will be visible to the struct instance and vice versa.

      The created instance holds a strong reference to the container object.
