Is there any function help me

i have an 1D float array on GPU memory, it represents an 2D image, but the (0,0) point is the center of image, i want move it to top left corner, any method to do with the 1D array? any suggestion is expected, please!

Please describe better, how the 1D float array maps to a 2D image. Are you talking about numbers or visualization? Or is it about Fourier transform (there you often have those kinds of shifts between different conventions).
