## 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.
