pgmstats(1)

NAME

pgmstats - print some statistics on a greyscale image

SYNOPSIS

pgmstats [<file>]

DESCRIPTION

pgmstats prints some statistics on a greyscale image file or stdin if no filename has been specified.

These statistics are currently the average value both based on the image's absolute or signed pixel values (signed pixel values can occur if the image format [PFI if enabled] supports this) and the square variance.

NOTES

The pgmstats 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, pgmstats may, if enabled, also be able to read PFI files. However using different file formats in the same command line may not be a good idea.

BUGS

None known yet.
