      The struct size in bytes.

    • ALIGNOF

      public static final int ALIGNOF
      The struct alignment in bytes.

    • SCANLINE_IDX

      public static final int SCANLINE_IDX
      The struct member offsets.

    • ROW_NUM

      public static final int ROW_NUM
      The struct member offsets.

    • PASS

      public static final int PASS
      The struct member offsets.

  • Constructor Details

    • spng_row_info

      public spng_row_info(ByteBuffer container)
      Creates a spng_row_info 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

    • sizeof

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

    • scanline_idx

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

    • row_num

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

    • pass

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

    • filter

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

    • malloc

      public static spng_row_info malloc()
      Returns a new spng_row_info instance allocated with memAlloc. The instance must be explicitly freed.

    • calloc

      public static spng_row_info calloc()
      Returns a new spng_row_info instance allocated with memCalloc. The instance must be explicitly freed.

    • create

      public static spng_row_info create()
