This option is used to specify the type of interlacing scheme for raw image formats such as `RGB` or `GRAY`. Choose from these interlace types:

  None
    do not interlace (RGBRGBRGBRGBRGBRGB...).
  Line
    use scanline interlacing (RRR...GGG...BBB...RRR...GGG...BBB...).
  Plane
    use plane interlacing (RRRRRR...GGGGGG...BBBBBB...).
  Partition
    like plane interlacing except the different planes are saved to individual files (e.g. image.R, image.G, and image.B).

The default scheme is None.

Use Line, or Plane to create an interlaced GIF or progressive JPEG image.
