    If no file names are specified, a PGM file from the standard input is assumed. Else each file from the command line will be processed.

NOTES

The pgminmax utility is part of the Wavelet class library package. The version number refers to the whole package rather than to the utility.

Apart from PGM, pgminmax may, if enabled, also be able to read PFI files.
