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.
