Oops...I think you took this in the wrong context. My discussion was aimed
at enlargers using LEDs as a light source, not scanners. Enlargers require
a 2d array, not a 1d array. With the scanner, it is very easy to calibrate
along the 1d axis...and the points are discrete. For an enlarger, they are
not discrete...and they are 2d.
