Hi, yes that would be nice. The basic file structure layout looks quite straight forward https://openexr.readthedocs.io/en/latest/OpenEXRFileLayout.html (even has sample "decode" at the end).

Would you like to help add a decoder? i'm a bit busy with other things at moment so can't promise when i get to it. But if you want to start before that i can help out of course.

I can try. Any tips ? where I should start ?

Sorry i didn't see the edited comment. Yes that is good start, and maybe good to look at some format decoder that looks similar, maybe tiff or png?
