No, I've never done this, but here is one important thought off the top of my head, don't just look for right answers, i.e. don't just check that the bubble in a certain location is suffieciently dark, also check the bubbles for wrong answers, else some crafty kid will darken all the bubbles and get a 100% :-)
Another thing, if you are also producing (printing) these tests then you could include registration marks that your software could use to help orient and locate the bubbles after scanning. -Glen > -----Original Message----- > From: Ray Horsley [mailto:[EMAIL PROTECTED] > Sent: Wednesday, July 16, 2003 14:11 > To: [EMAIL PROTECTED] > Subject: Scanner Software > > > > Has anybody had any experience writing something which will > read [interpret] > an image?
