rawtoppm


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  exten-
              sion,  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.
