pnmsplit [options] input output

pnmsplit splits a multi-image PNM stream into individual files. PNM files can contain multiple images concatenated together, and this tool extracts each one into a separate output file.
The output filename pattern must contain a %d format specifier (or variant like %03d) which is replaced with the image sequence number starting from 0. The -padname option controls zero-padding width for the numbering. This is useful for processing animation frames or batch image sequences. Part of the Netpbm toolkit.
