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.
