NAME
       anytopnm - convert an arbitrary type of image file to PBM,
       PGM, or PPM

SYNOPSIS
       anytopnm [file]

DESCRIPTION
       anytopnm converts the input image, which may be in any  of
       dozens  of  graphics  formats, to PBM, PGM, or PPM format,
       depending on that nature of the input image,  and  outputs
       it to Standard Output.

       To  determine  the  format of the input, anytopnm uses the
       file program (possibly assisted by the magic numbers  file
       fragment	 included  with Netpbm).  If that fails (very few
       image formats have magic numbers), anytopnm looks  at  the
       filename extension.  If that fails, anytopnm punts.

       The type of the output file depends on the input image.

       If  file	 indicates  that  the  input  file  is compressed
       (either via Unix compress,  gzip,  or  bzip  compression),
       anytopnm	 uncompresses  it  and proceeds as above with the
       uncompressed result.

       If file indicates that the input file is encoded by  uuen
       code  or	 btoa,	anytopnm decodes it and proceeds as above
       with the decoded result.

       If file is - or not given, anytopnm takes its  input  from
       Standard Input.
