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.
