rawtoppm(1)                                           rawtoppm(1)

NAME
       rawtoppm - convert raw RGB bytes into a portable pixmap

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

DESCRIPTION
       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 .

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

       -rowskip
              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 (per-
              haps using dd), turning each part into a  PGM  file
              with   rawtopgm,   and  then  combining  them  with
              rgb3toppm.
