| Value | Defined Constant | Meaning |

| 1 | IG_ISIS_BAR_AUTOREADFRONT_ON | Automatically search for barcodes on the front side. |
Use IG_ISIS_TAG_BAR_AUTOREADFRONT to enable automatic barcode search on front sides of a duplex scan using the current barcode search parameters. The search is done after each image is read and before the driver returns IG_ISIS_ERR_ENDZONE. If the driver supports this tag and you choose not to enable automatic search, then you need to call IG_ISIS_drv_send with the message IG_ISIS_DRV_READBARDATA when you want to search a particular page for barcode information. If the driver supports barcode detection but does not support this tag specifically, then automatic search is always enabled.
