NAME
       exrmetrics - report read/write time

SYNOPSIS
       exrmetrics [options] infile [infile2...]	[-o outfile]

DESCRIPTION
       Read  an	 OpenEXR image from infile, write an identical copy to outfile
       reporting time taken to read/write and file sizes.

OPTIONS
       -o file
	      file to write to.	If no file specified,  uses  a	memory	buffer
	      note: file may be	overwritten multiple times during tests

       -p n   part number to copy, or "all" for	all parts default is "all"

       -m     set to multi-threaded (system selected thread count)

       -t n   Use a pool of n worker threads for processing files.  Default is
	      single threaded (no thread pool)

       -l level
	      set DWA or ZIP compression level

       -z,--compression	list
	      list	 of	  compression	    methods	  to	  test
	      (none/rle/zips/zip/piz/pxr24/b44/b44a/dwaa/dwab,orig,all default
	      orig: retains original method)

       --convert
	      shorthand	options	for writing a new file with no metrics:	-p all
	      --type orig --time none --type orig --no-size --passes 1	change
	      pixel  type  or  compression  by	specifying  --type or -z after
	      --convert

       --bench
	      shorthand	options	for robust performance	benchmarking:  -p  all
	      --compression   all   --time  write,reread  --passes  10	--type
	      half,float --no-size --csv

       -16 rgba|all
	      [DEPRECATED] force 16 bit	half float: either just	RGBA,  or  all
	      channels Use --type half or --type mixed instead

       --pixelmode list
	      list  of	pixel  types to	use (float,half,mixed,orig) mixed uses
	      half for RGBA, float for others. Default is 'orig'

       --time list
	      comma separated list of operations to report timing for.	opera-
	      tions can	be any of read,write,reread (use --time	 none  for  no
	      timing)

       --no-size
	      don't output size	data

       --json print output as JSON dictionary (Default mode)

       --csv  print  output  in	 csv mode. If passes>1,	show median timing de-
	      fault is JSON mode

       --passes	num
	      write and	re-read	file num times (default	1)

       -h, --help
	      print this message

       -v     output progress messages

       --version
	      print version information
