How to read DirextX texture from the device ?

Hello, I want to know if it is possible to read existing DirectX texture from the device using DirectCompute

yes, there is a program that can pull textures off of direct x games. it also can modifi them without changing the game. its a awesome little program called texmod
this thing is really cool, i used to to mod massefect 2, on of my friends used to for screwing up sanadreas.
