I need to work with a 'receipt fields scanning' scenario. I was wondering which is the best approach for it:
1.- Use 'processTextField' method adding regExp param with the name of my fields to recognize. 2.- Use 'processImage' method doing the regular expression on my side.
Of course my best option is clearly the first one, since the system does the processing. So is it possible? Because I've tried to set the 'processTextField' with 'regExp' parameter but I do n't get any success on it.
