NAME

       anytopnm - attempt to convert an unknown type of image file to a portable anymap

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 uuencode 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.
