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