OPENSLIDE-QUICKHASH1SUM(1)	 User Commands	    OPENSLIDE-QUICKHASH1SUM(1)

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.
