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.
