I don't know the details of OpenEXR so I'm afraid there's anything I can help with here. There's an OpenEXR_jll so you could start with an [OpenEXR.jl] package, then register it to ImageIO and FileIO when it works.

PNGFiles.jl is a good example for this image io wrapper library.

Thanks for the offer. I created this task just as a placeholder for work I'm doing to make this happen. I created the OpenEXR build recipe behind OpenEXR_jll last night, and I'm currently trying to tweak the build recipe for ImageMagick_jll to link it in without complaint. Lastly will be making any patches here to close the loop.

Great to know that! If you need to host OpenEXR.jl under JuliaIO (as ImageIO and PNGFiles do) and let us image people to co-maintain it, please ask without any hesitation.

It is looking difficult to get ImageMagick_jll built with support for OpenEXR. I'm currently in the process of writing a small standalone julia package that wraps the C interface in a FileIO-compatible way. Since it doesn't look like the functionality will be exposed via ImageMagick, I'm closing this.
