If I duplicate the column 9 times, so that there's ten columns with the same numbers, it reads it correctly. Running these results through the training tools didn't help it recognize the original image, though. Running tesseract on images with a single digit yielded nothing as well.
In my program, do I have to programatically duplicate my column of numbers several times and then figure out what the result was supposed to be... or can I train tesseract to recognize a single column? I suppose duplicating it will work, but it seems like a bad hack.
