NAME

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



SYNOPSIS

       anytopnm [file]



DESCRIPTION

       This program is part of Netpbm(1).

       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
       Input.
