Being new to this, I have tried looking up the functionalities of GIL. I was thinking of implementing the addition of negative image conversion as well to GIL, incorporating the usage of parallel programming using OpenMP library. Is there any demand for that?

(speaking as one of current maintainers of GIL.) I can't tell if there is a demand, but if you have a use case for that and you'd like to contribute it for GIL, then go for it and feel free to contribute to GIL You can propose it as an extension.

I feel that parallel programming will massively improve the computational efficiency of GIL.

There is this old but usable extension by VIctor Bogado https://github.com/boost-gil/gil_threaded Although I am not a user of OpenMP myself, I have used GIL in multi-threaded processing of images, using Microsoft PPL or Intel TBB. Generally, it's a very interesting topic to explore. Best regards, -- Mateusz Loskot, http://mateusz.loskot.net
