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.
