       rawtoppm - convert raw RGB bytes into a portable pixmap


       rawtoppm [-headerskip N] [-rowskip N] [-rgb|-rbg|-grb |-gbr|-brg|-bgr ]
       [-interpixel|-interrow] width height [imagedata]


       Reads raw RGB bytes as input.  Produces a portable  pixmap  as  output.
       The  input  file  is just RGB bytes.  You have to specify the width and
       height on the command line, since the program obviously can’t get  them
       from  the  file.   The  maxval  is assumed to be 255.  If the resulting
       image is upside down, run it through pnmflip -tb .


              If the file has a header, you can use this flag to skip over it.

              If  there  is  padding  at the ends of the rows, you can skip it
              with this flag.

       -rgb -rbg -grb -gbr -brg -bgr
              These flags let you specify alternate color orders.  The default
              is -rgb.

       -interpixel -interrow
              These flags let you specify how the colors are interleaved.  The
              default is -interpixel, meaning interleaved by pixel.  A byte of
              red,  a  byte  of  green,  and a byte of blue, or whatever color
              order you specified.  -interrow means interleaved by row - a row
              of  red,  a  row  of green, a row of blue, assuming standard rgb
              color order.  An -interplane flag  - all the  red  pixels,  then
              all  the  green,  then  all  the  blue  -  would  be  an obvious
              extension, but is not  implemented.   You  could  get  the  same
              effect  by  splitting  the  file into three parts (perhaps using
              dd), turning each part into a PGM file with rawtopgm,  and  then
              combining them with rgb3toppm.
