+.SH NAME
+anytopnm - convert an arbitrary type of image file to PBM, PGM, or PPM
+
+.UN synopsis
+.SH SYNOPSIS
+
+\fBanytopnm\fP [\fIfile\fP]
+
+
+.UN description
+.SH DESCRIPTION
+.PP
+This program is part of
+.BR "Netpbm" (1)\c
+\&.
+.PP
+\fBanytopnm\fP 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.
+.PP
+To determine the format of the input, \fBanytopnm\fP uses the
+\fBfile\fP program (possibly assisted by the magic numbers file
+fragment included with Netpbm). If that fails (very few image formats
+have magic numbers), \fBanytopnm\fP looks at the filename extension.
+If that fails, \fBanytopnm\fP punts.
+.PP
+The type of the output file depends on the input image.
+.PP
+\fBanytopnm\fP 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
+\fBanytopnm\fP adds is the ability to recognize the format and choose
+the appropriate Netpbm program to convert it. For example, if you
+invoke \fBanytopnm\fP on a GIF file, \fBanytopnm\fP will recognize
+that it is a GIF file and therefore \fBgiftopnm\fP knows how to
+convert it to PNM, so \fBanytopnm\fP invokes \fBgiftopnm\fP.
+.PP
+\fBanytopnm\fP cannot recognize every possible input format, so you
+may still be able to convert an image with a specific Netpbm program when
+\fBanytopnm\fP fails to convert it.
+.PP
+If \fBfile\fP indicates that the input file is compressed (either
+via Unix compress, gzip, or bzip compression), \fBanytopnm\fP
+uncompresses it and proceeds as above with the uncompressed result.
+.PP
+If \fBfile\fP indicates that the input file is encoded by uuencode
+or btoa, \fBanytopnm\fP decodes it and proceeds as above with the
+decoded result.
+.PP
+If \fIfile\fP is \fB-\fP or not given, \fBanytopnm\fP takes its
+input from Standard Input.
+.PP
+Many image formats are capable of representing multiple images. In
+most cases, \fBanytopnm\fP converts these to multi-image Netpbm images,
+but for some formats, \fBanytopnm\fP converts only the first image and
+ignores the rest.
+.PP
+In the case of a multi-image GIF input, \fBanytopnm\fP converts all the
+images starting with Netpbm 10.69 (December 2014), but only the first in
+earlier releases.

+.SH OPTIONS
+.PP
+There are no command line options defined specifically
+for \fBanytopnm\fP.
+
+\fBanytopnm\fP does not recognize the options common to all
+programs based on libnetpbm (See
+.UR index.html#commonoptions
+ Common Options
+.UE
+\&.) However, the \fB-version\fP option works.
