Get mouse cursor image position

Get mouse cursor image position

I get the mouse position, and the mouse image (icon). but i need one more
thing that I can't find anywhere: How Can I get the location of the cursor
in the icon that represent the mouse position, mean: every icon of the
mouse cursor have diff location, for example the default mouse cursor
would be in the 0,0 of the icon, but in the move icon, the cursor would be
in the center of the image (icon).
