    • FT_Bitmap

      public FT_Bitmap(ByteBuffer container)
      Creates a FT_Bitmap 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.

  • Method Details

      public int sizeof()
      Description copied from class: Struct
      Returns sizeof(struct).
      Specified by:
      sizeof in class Struct<FT_Bitmap>

      public int pitch()
      Returns:
      the value of the pitch field.

    • buffer

      public @Nullable ByteBuffer buffer(int capacity)
      Returns:
      a ByteBuffer view of the data pointed to by the buffer field.

    • num_grays

      public short num_grays()
      Returns:
      the value of the num_grays field.

      public byte palette_mode()
      Returns:
      the value of the palette_mode field.

    • palette

      public long palette()
      Returns:
      the value of the palette field.
