NAME

       rawtoppm - convert a stream of raw RGB bytes to a PPM image

SYNOPSIS

       rawtoppm

       [-headerskip N]

       [-rowskip N]

       [ -rgb|-rbg|-grb |-gbr|-brg|-bgr ]

       [-interpixel|-interrow] width height

       [imagedata]

DESCRIPTION

       This program is part of Netpbm(1).

       rawtoppm  reads  raw  RGB  bytes as input and produces a PPM image 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.  rawtoppm assumes the maxval of the input samples is 255, and makes the maxval of
       the output PPM 255.

       rawtoppm  assumes  the pixels come top first in the input stream.  If they are actually bottom first, the
       resulting PPM is upside down, so run it through pamflip -tb.

OPTIONS

       In addition to the options common to all programs based on libnetpbm (most notably  -quiet,  see   Common
       Options ), rawtoppm recognizes the following command line options:

       -headerskip
              Skip  over  this  many bytes at the beginning of the input stream.  Use this option when the input
              has some kind of header followed by a raster suitable for rawtoppm.

       -rowskip
              Skip this many bytes at the end of each row of the raster.  (Some input streams  have  padding  at
              the end of rows).

       -rgb -rbg -grb -gbr -brg -bgr
              This option specifies the order of the color components for each pixel.  The default is -rgb.

       -interpixel -interrow
              These  options  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 option - 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.
