FSlateShaderResource get pixel data

Can I somehow get the raw pixel data from FSlateShaderResource?

So I’ve got into small progress here, but I need a bit more explanation, because the documentation that was writtin for thouse is just uninformative at all.

I’ve found a code that transforms (cast) FSlateShaderResource into FTexture2DRHIRef which I can ue it later using FRHICommandListImmediate::ReadSurfaceData() method and get pixel data of the texture, however I get some crazy errors when writting this piece of code. I am including this header:

#include “Rendering/SlateRenderer.h”

Do I need to include something else?
