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

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
       Input.
