A customer is interested in having Barcode Xpess optionally perform multiple reads over an image in the process of analyzing for the barcode. Currently the AdditionalReadingPass will perform that once. But, they're interested in having a number of other passes performed on slight variations of the image in hopes to gain a successful read. They mentioned that slower performance would be acceptable if it would help to obtain a successful read.
Having this ability can help gain a higher number of successful barcode reads.
