NAME
       pamsplit - split a multi-image PNM/PAM file into single-image files


SYNOPSIS
       pamsplit

       [netpbmfile

       [ output_file_pattern]]

       [-padname=n]

       Minimum	unique abbreviation of option is acceptable.  You may use dou-
       ble 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 specification of the input file, or - to indi-
       cate 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, pamsplit fails.

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

       The -padname option specifies to 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 -  output-
       file%d.ppm  -padname=3  would yield output filenames outputfile000.ppm,
       outputfile001.ppm, etc.

       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.

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