NAME

       pnmsplit - split a multi-image portable anymap into multiple single-image files

SYNOPSIS

       pnmsplit [pnmfile[ output_file_pattern]]

DESCRIPTION

       Reads a Netpbm file as input.  Copies each image in the input into a separate file, in the same format.

       pnmfile is the file specification of the input file, or - to indicate Standard Input.  The default is Standard Input.

       output_file_pattern  tells  how to name the output files.  It is the file specification of the output file, except that the first occurence
       of "%d" in it is replaced by the image sequence number in unpadded ASCII decimal, with the sequence starting at 0.  If there is no "%d"  in
       the pattern, pnmsplit fails.

       The default output file pattern is "image%d".

       Note  that  to do the reverse operation (combining multiple single-image PNM files into a multi-image one), there is no special Netpbm pro-
       gram.  Just use cat.

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.
