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.


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.
