That's the point of @Blosc2 being a meta-compressor for numerical data, you can do what ever you want, if you are interested look at the #OpenEXR usages, and filters presented for @aras_p:

I just released a new Blender extension for blurring images and scene backgrounds: https://extensions.blender.org/add-ons/blur-hdri/

Under the hood, it uses the image processing libraries @pillow and #OpenEXR.

If you have ideas to build blender extensions yourself, join Brady Johnston and me at our talk “Extensions are Coming” at the Blender Conference next week, were we will be talking about how to develop Blender extensions. https://conference.blender.org/2025/presentations/4028/
(Recordings will be available as well.)

#OpenEXR best practices
- Real-Time Playback/Compositing: Use B44/B44A or DWA for faster I/O .
- CGI/Rendered Content: ZIP (lossless) or PIZ (smaller files) .
- Texture Maps: ZIP for fast access .
- Layered EXRs: ZIPS for scanline efficiency .
- Avoid Lossy Compression for non-color data (e.g., normals, depth). #exr #vfx #rendering #b3d #CGI

Powiedziałbym, że dla #EasyCLA bardziej pasowałaby nazwa "skomplikowane i zepsute CLA".

Po tym, jak w końcu udało mi się wysłać wniosek o CLA dla #OpenEXR, firma dalej go nie widziała. Spróbowałem jeszcze raz, i tym razem udało im się zaakceptować. Tyle że EasyCLA dalej twierdziło, że nie jest podpisane.

Ale już po problemie, bo jakiś przypadkowy typ postanowił wziąć moją łatkę, wraz z oryginalnym opisem zmian, usunąć moje dane osobowe i wysłać ją, przy okazji zamykając moją — a autorzy od razu to przyjęli. Nie, żeby to robiło jakąś szczególną różnicę, bo łatka była trywialna (do tego stopnia, że ta cała bieganina wokół CLA nie miała żadnego sensu), ale i tak niefajnie, jak ktoś kradnie twoją pracę i usuwa autorstwo.

I dare say a better name for #EasyCLA would be "convoluted and broken CLA".

Even after I was finally able to submit the CLA for #OpenEXR, the company couldn't find it. After another attempt, they were finally able to approve it. Except that it still claimed I'm unapproved.

However, that's not a problem anymore, because some random decided to take my patch, up to the commit message, wipe my authorship from it and submit it with a closing tag on my pull request — and upstream gladly merged that. I mean, it was a trivial patch (so trivial the whole CLA business was entirely pointless), so it's not like it matters, but it still feels wrong when people steal your work and remove authorship.
