pnmsplit(1)                            General Commands Manual                           pnmsplit(1)



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 program.  Just use cat.
