How to create a completely non anti-aliased image...

see the white dots on the body outline... by the way this thing is transparent and is being displayed on desktop via an application... anyways...
- 1 - what i did was took a stock image of body...
- 2 - removed background
- 3 - selected the left area that is the body and painted it...
- 4 - then expanded the selection 1px and inverted the selection.. and painted the slection
- 5 - so the body outline was empty
- 6 - then i selected the empty area and painted it in a new layer
- 7 - got rid of the previous layer...
during 6 i am not getting solid painting... its antialiasing the filling or brush paint etc...
can any one tell me how to make it completely non-anti-alias
