I have a nodeJS script that automatically creates random .PNG images. The idea is to add a filter after the creation process.

My designer configured this filter via a LUT (.cube or .look), the question is how to apply it to a png automatically?

I found a script from @abbath but it uses canva LUTs, which I don't have? https://gist.github.com/kishmiryan-karlen/559c190f6c20856ee323

Thanks for your help !
