You WILL see lines if the resolution of the sensor is sufficient to acquire the lines. Lines can even span multiple sensors...duh. Have you EVER actually used a scanner (I know you say you have, but now I am skeptical that you really have), or you playing perception games now? "Well, what IS a line anyway"? Your statement is just plain foolish, and continues to show you either just don't understand this, or as I suspect, are playing games. > > By your understanding, you could just use one > > pixel to sample the entire scene! > > You need at least two pixels.

You really don't know what you're talking about, or you're just being an ass and being argumentative for the sake of being argumentative. My guess is both. You really have become a complete waste of time and completely annoying, as other people have warned me you would. I'll bet you even argue with your self, and forget which side you took...
