NAME

openslide-quickhash1sum - Print OpenSlide quickhash-1 checksums

SYNOPSIS

openslide-quickhash1sum [--help] [--version] slide...

DESCRIPTION

Print OpenSlide quickhash-1 checksums for one or more virtual slide files, in a format similar to sha256sum(1).

quickhash-1 is a non-cryptographic, 256-bit hash of a subset of a slide's data. It uniquely identifies a particular virtual slide, but cannot be used to detect corruption or modification of the slide file.

OPTIONS

--help: Display usage summary.
--version: Display version and copyright information.

EXIT STATUS

openslide-quickhash1sum returns 0 on success, 1 if a quickhash-1 could not be calculated, or 2 if the arguments are invalid.

NOTES

openslide-quickhash1sum is a legacy command and no new features will be added. Its replacement is the slide quickhash1 subcommand of slidetool(1).

BUGS

quickhash-1 is not defined for all slide files supported by OpenSlide. If a slide does not have a quickhash-1, "No quickhash-1 available" will be printed.
