Any alternatives to Slimraw?
I have not tested it, but it seems like OpenEXR https://www.openexr.com/ is an alternative to Slimraw

HELP! Rendered over 100frames over night and ended up with unmerged AOVs. Is there anyway I can merge all of these manually into a sequence? "Merge AOVs" (and all other settings that normally work were turned on). I've managed to fix settings, my biggest concern is salvaging these frames.
Since its already rendered, you can check the beauty pass to see if it is already in a merged format. Change the extension to .exr and open it with EXR-IO https://www.exr-io.com/ in photoshop to see if your AOVs exist as layered data already. Depends on your settings of course if its in that format. Otherwise you will need to script the merge using some openexr tools available at https://www.openexr.com.

Ask HN: Do you still use TIFF image format?
Visual Effects artist here. Nope. We're all on EXRs mainly (and of course JPGs)

How should CMAKE_CXX_FLAGS be formated in CMAKE GUI?
Forgive the noob question (but that's what I am when it comes to CMAKE :D), but I'm currently trying to build Imathto use it with OpenEXR.

Problems building Natron 2.4
It looks like openexr has recently removed IlmBase: https://github.com/AcademySoftwareFoundation/openexr/pull/929

Why is some private company's niche image format being pushed out as a universal Ubuntu update??
Well, OpenEXR is open-source. It's not as though they're trying to turn a profit from it. People don't have to use it if they don't want.

Building an online image compressor
After some research, I found libvips, a demand-driven, horizontally threaded image processing library. It is designed to run quickly while using as little as memory as possible.

Things you might not know about Next Image
Sharp is a fast and efficient image optimization Node.js module that makes use of the native libvips library.

Go Image Converting
h2non/bimg can handle both if the underlying libvips is compiled with support for both formats.

.Webp is the bane of my existence
if you're using linux (which it doesn't seem so) there's also vispdisp https://github.com/jcupitt/vipsdisp which is based on https://github.com/libvips/libvips which will likely take over how images are decoded in the future for everything, at least methodology wise.

How are responsive image sets are generated, stored, and managed server-side?
The magic happens by way of a library called Libvips, which contains an ultra-high-speed low-memory image resizer.

imagor v1 - a fast, Docker-ready image processing server in Go, libvips and more
imagor uses one of the most efficient image processing library libvips. It is typically 4-8x faster than using the quickest ImageMagick and GraphicsMagick settings.
