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

alt text

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

Try Image-menu, Adjustments, Posterize with two levels (afterwards you may have to remove the 2nd of the two colors with the magic-wand selection tool (non-continous selection)).

the resulting image isn't so great because of staircase effect but yo did solved the "asked" problem... –  Junaid Saeed Aug 3 '10 at 7:04
    
Maybe you can improve the whole thing if you use the antialiased image with a bit of layer transparency and put it under the the non-antaliased version. Or you could turn the antialiasing into transparency (roughly speaking something along the lines of this article, lighter pixels more opaque than dark ones: darkhorizons.emissionline.com/PSSelect.htm ) –  Nicholaz Aug 3 '10 at 14:09

You can get a lot of mileage out of shifting to indexed color (Image->Mode->Indexed Color) and then back to RGB. I copied the image from your question, converted to Indexed Color (Local/Adaptive, 2 colors, Forced Black & White) and ended up with a non-antialiased image. From there, I shifted back to RGB color and made tonal adjustments using the B&W as a basis.
