repository is currently not maintained and after knowing much better the OpenEXR format, there is a lot of missing features that shall have been supported:\n- No support for displayWindow\n- No support for chromaticities\n\nIf you want to use the proper tool, I recommend using OpenImageIO tools: https://openimageio.readthedocs.io/en/v2.2.15.1/oiiotool.html\n\nSo, take this repo with a grain of salt, an example on how to read OpenEXR images using the OpenEXR library, not as the state of the art.\n\nOpenEXR converter\n=================\n\nThese tools are simple utilities to convert images files from OpenEXR to PNG 8bit sRGB files and TIFF to OpenEXR.\n\nChecking out the repository\n===========================\n\n```\ngit clone git@github.com:yama-chan/openexr-converter.git\ngit submodule update --init --recursive\n```\n\nCompilation\n===========\n\nDependencies\n------------\nYou need to install OpenEXR to compile the tool:\n* libopenexr\n* libtiff\n\n### Ubuntu 16.04 LTS\n\n```\nsudo apt install libopenexr-dev libtiff5-dev\n```\n\n### Arch Linux\n\n```\nsudo pacman -S openexr libtiff\n```\n\n### Compilation\nIn order to compile in a folder build the tool, do:\n\n```\nmkdir build\ncd build\ncmake ..\nmake\n```\n\nAfter compilation,\n* `exr-png` will be created in `src/exr-png` folder.\n* `tiff-exr` will be created in `src/tiff-exr` folder.\n\nTo install, do:\n\n```\nsudo make install\n```\n\nUsage\n=====\n\nOpenEXR to PNG\n--------------\n\n```\nexr-png  [-g \u003creal\u003e] [-a] -o \u003cstring\u003e -i \u003cstring\u003e [--] [--version]\n\t\t [-h]\n```\n\nWhere:\n\n```\n   -g \u003creal\u003e,  --gamma \u003creal\u003e\n     Set the gamma correction (default sRGB)\n\n   -a,  --ignore-alpha\n     Ignore alpha channel\n\n   -o \u003cstring\u003e,  --output \u003cstring\u003e\n     (required)  Set file to save to\n\n   -i \u003cstring\u003e,  --input \u003cstring\u003e\n     (required)  Set file to convert\n\n   --,  --ignore_rest\n     Ignores the rest of the labeled arguments following this flag.\n\n   --version\n     Displays version information and exits.\n\n   -h,  --help\n     Displays usage information and exits.\n```\n\n\nTIFF to OpenEXR\n---------------\n\n```\ntiff-exr \u003cinput_tiff_file\u003e \u003coutput_exr_file\u003e\n```\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fafichet%2Fopenexr-converter","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fafichet%2Fopenexr-converter","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fafichet%2Fopenexr-converter/lists"}
