NAME
       anytopnm - attempt to convert an unknown type of image file to a porta-
       ble 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 pro-
       ceeds 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 In-
       put.
