EXRMETRICS(1) User Commands EXRMETRICS(1) 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 re- porting 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/htj2k256/htj2k32,orig,all default orig: retains original method) --convert shorthand options for writing a new file with no metrics: -p all --time none --pixelmode orig --no-size --passes 1 change pixel data type/compression by specifying --pixelmode/-z after --convert --bench shorthand options for robust performance benchmarking: -p all --com- pression 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 chan- nels Use --pixelmode half or --pixelmode mixed instead --pixelmode list list of pixel data 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 --part-disk-size Output the on-disk size of the data portion of each part in a multi- part EXR file (including chunk headers). File output (-o) is not supported when using this option --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 [ ] COPYRIGHT Copyright (C) Contributors to the OpenEXR Project License BSD-3-Clause [ ] OpenEXR 3.4.15 https://openexr.com August 2026 EXRMETRICS(1)
