I always do this kind of stuff with Jeff Poskanzer's PBM tools.
The the pksrc name for the whole toolkit is "netpbm".

In this case, rawtopgm(1) would probably your first step of a command
pipeline, finishing with any of the pgmto... or pnmto... tools to create
your target format; optionally with some transformations wegded in
in between.

NAME
       rawtopgm - convert raw grayscale bytes into a portable graymap

SYNOPSIS
       rawtopgm  [-bpp  [1|2]]  [-littleendian]  [-maxval  N]  [-headerskip N]
       [-rowskip N] [-tb|-topbottom] [width height] [imagefile]

DESCRIPTION
       Reads raw grayscale values as input.  Produces a PGM  file  as  output.
       The input file is just a sequence of pure binary numbers, either one or
       two bytes each, either bigendian  or  littleendian,  representing  gray
       values.   They  may  be arranged either top to bottom, left to right or
       bottom to top, left to right.  There may be arbitrary  header  informaâ??
       tion  at  the start of the file (to which rawtopgm pays no attention at
       all other than the header's size).
