Detecting pixel colors inside images

Hello, I require some assistance on this issue.

I have a 32x32 image variable, and I need a way to get the colour value of each pixel.
I never coded anything like this, so I have no clue how to execute this. I would appreciate any help possible regarding this matter.

Thank you in advance

Hello! The question is where do you want to do it - in Material Editor, in some object CPP, in some object BP?

Im also looking how to do this in material custom node. Trying to do gaussian blur on a material texture (not scene texture) and that needs access to a pixel’s neighbors

Can you share nodes, pictures, etc? I dont understand what problem you are trying to solve
