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. operations 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 default 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
