NAME

       pamsplit - split a multi-image Netpbm file into single-image files

SYNOPSIS

       pamsplit

       [netpbmfile

       [ output_file_pattern]]

       [-padname=n]

       Minimum  unique  abbreviation of option is acceptable.  You may use double hyphens instead
       of single hyphen to denote options.  You may use white space in place of the  equals  sign
       to separate an option name from its value.

DESCRIPTION

       This program is part of Netpbm(1).

       pamsplit  reads  a  PNM  or PAM stream as input.  It copies each image in the input into a
       separate file, in the same format.

       netpbmfile is the file name 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 name of the output
       file, except that the first occurrence 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, pamsplit fails.

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

       The -padname option specifies how many characters you want the image  sequence  number  in
       the  output  file  name  padded  with  zeroes.   pamsplit adds leading zeroes to the image
       sequence number to get up to at least that number of characters.  This is just the  number
       of  characters  in  the  sequence  number  part  of  the  name.   For  example, pamsplit -
       outputfile%d.ppm   -padname=3   would   yield    output    filenames    outputfile000.ppm,
       outputfile001.ppm, etc.

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

       If you just want to find out basic information about the images in a stream, you  can  use
       pamfile on the stream.

       To extract images from a stream and generate a single stream containing them, use pampick.

       To  run  a  program  on  each image in a stream without the hassle of temporary files, use
       pamexec.

OPTIONS

       In addition to the options common to all programs based on libnetpbm (most notably -quiet,
       see
        Common  Options  ⟨index.html#commonoptions⟩  ), pamsplit recognizes the following command
       line option:

       -padname=n
              Specify the width (i.e. number of digits) of the image sequence number field in the
              filenames  of  the  output  files.   The image sequence will be padded with leading
              zeroes to achieve the stated width.

              The default is no padding (equivalent to -padname=0).

              The -padname option was new in Netpbm 10.23 (July 2004).  Before  that,  there  was
              never any padding.
