It is probably much simpler to create a surface of the right size, lock it, copy your data to the surface (line by line since you need to respect the pitch) and unlock the surface. Alternatively you can also create a surface around your image data. You don't even need to do the copying then. That's what the DSDESC_PREALLOCATED flag is good for.
