I've created a gray scale in gimp of 11 successive squares going from
pure black (0,0,0) to pure white (255,255,255) going up in equal
increments.
I want to read the values on my display as seen by my Eye-One-Pro. I am
trying to use spotread , but I apparently don't understand what I'm
doing.
Problems:
1. I use -N, but it still insists of calibration.
There may be a couple of bugs have crept into this option.
2. It asks me about FWA, which I don't understand. I skipped that and
just pressed a key to get XYZ and Lab readings. But the readings don't
seem to make sense. In particular the L readings don't decrease
consistently from white to black. I've tried -d, -db, and -e.
-d should do it. What sort of readings do you get ?
