-interlace type
the type of interlacing scheme.	

Choose from:

   none
   line
   plane
   partition
   JPEG
   GIF
   PNG

This option is used to specify the type of interlacing scheme for raw image formats such as RGB or YUV.
None means do not interlace (RGBRGBRGBRGBRGBRGB...),
Line uses scanline interlacing (RRR...GGG...BBB...RRR...GGG...BBB...), and.
Plane uses plane interlacing (RRRRRR...GGGGGG...BBBBBB...).
Partition is like plane except the different planes are saved to individual files (e.g. image.R, image.G, and image.B).
Use Line or Plane to create an interlaced PNG or GIF or progressive JPEG image.
To print a complete list of interlacing schemes, use -list interlace.
