IG_ISIS_TAG_TYPE_LONG
Some drivers for scanners that support barcode detection.
| Value | Defined Constant | Meaning |
|---|---|---|
| 0 | IG_ISIS_BAR_AUTOREADBACK_OFF | Do not automatically search for barcodes on the back side. |
| 1 | IG_ISIS_BAR_AUTOREADBACK_ON | Automatically search for barcodes on the back side. |
Use IG_ISIS_TAG_BAR_AUTOREADBACK to enable automatic barcode search on back 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.
