rawtopgm(1)              UNIX System V(15 December 89)              rawtopgm(1)


NAME
      rawtopgm - convert raw grayscale bytes into a portable graymap

SYNOPSIS
      rawtopgm [-headerskip N] [-rowskip N] width height [imagedata]

DESCRIPTION
      Reads raw grayscale bytes as input.  Produces a portable graymap as
      output.  The input file is just grayscale 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.  Note that rowskip can be a real number.  Amazingly, I
            once had an image with 0.376 bytes of padding per row.  This turned
            out to be due to a file-transfer problem, but I was still able to
            read the image.
