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

       anytopnm	[file]

       This program is part of Netpbm(1).

       anytopnm	 converts  the	input  image, which may	be in any of about 100
       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

       The type	of the output file depends on the input	image.

       anytopnm	 uses  the converters for particular graphics formats that are
       in the Netpbm package, so it can't convert any format that you couldn't
       convert	with  some  other  Netpbm  program.  What anytopnm adds	is the
       ability to recognize the	format and choose the appropriate Netpbm  pro-
       gram to convert it.  For	example, if you	invoke anytopnm	on a GIF file,
       anytopnm	will recognize that it is a GIF	file  and  therefore  giftopnm
       knows how to convert it to PNM, so anytopnm invokes giftopnm.

       anytopnm	cannot recognize every possible	input format, so you may still
       be able to convert an image with	a specific Netpbm  program  when  any-
       topnm fails to convert it.

       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-

       Many  image  formats  are  capable of representing multiple images.  In
       most cases, anytopnm converts these to multi-image Netpbm  images,  but
       for  some  formats,  anytopnm converts only the first image and ignores
       the rest.

       In the case of a	multi-image GIF	input, anytopnm	converts all  the  im-
       ages  starting with Netpbm 10.69	(December 2014), but only the first in
       earlier releases.
