@akash-akya, I’m answering this question on Elixir forum using Vix/Image because its a fun problem which is trivial with Operation.xyz/3 - except I don’t think we can currently stream raw image data, only formatted images, with Image.write_to_stream/2.

Do you see any possibility of streaming the raw pixel data, rather than the formatting image?

PS: I know Vix is not the optimal solution to the problem as stated, but since there are no answers after a few days I think its cool to show that Vix/Image can do this - albeit the whole image needs to be rendered in memory, not streamed unless you know a way.
