I don't know if theres a way to solve my problem, but I still wan't to ask.
Is there a way of analysing a picture(black and white)to find out how many
pixels are very dark(black) and how many are very light?
Thanks already :)

do a loop that increses variables like this:

foreach pixel
  if it is white increse white
  else if it is black increse black

white now has the number of white pixels and black the number of black.

Thanks a lot but how do I check each pixel?(with an array?)
could some on give me an example please.

This example is based on a TBitmap:

  with Bitmap do
    for x := 0 to Width-1 do
      for y := 0 to Height-1 do 
        case Canvas.Pixels[x, y] of
          clWhite: Inc(NumberOfWhite);
          clBlack: Inc(NumberOfBlack);
        end;
