For obvious reasons, the laser beam of a barcode scanner cannot read a barcode that is displayed on your monitor. However, if the resolution of the display is high enough to detect the differences in line-thickness of each bar... Is it possible for Revolution to take a snapshot of a 1 pixel height strip across the displayed barcode and show in a field what the alpha-numeric values are? What I want to build is a "digital" barcode verifier to simply confirm that the content of the code is correct BEFORE printing it.
I think I can handle the snapshot of the strip of pixels, but I have no idea how to begin analyzing the on/off pixels to determine their value. Can anyone offer suggestions? Have you attempted anything similar and have code snippets that you would share? Thanks.
