Significant skew : enable this option if there is a possibility that
barcodes could be skewed on a page. Significant skew means more
that 15 degrees.
Confidence : enter a confidence level if you want to restrict what
the software will consider to be a successful reading.
When reading a barcode, the software reader indicates how
confident it was in correctly reading the barcode (see: Project setup,
Scanning, Barcode/OCR, Testing barcodes and OCR zones). If this
confidence percentage (between 0 and 100%) falls below the
specified confidence level, then a barcode value is not returned.
Quality : if you notice that the quality of the barcodes to be read is
rather poor, slide the quality indicator to the left. This will however
slow down the barcode reading.
Allow out-of-specs barcodes : tick this option if you suspect the
barcodes to be "out-of-specs", i.e. that they have been generated
without respecting the barcodes specifications.
Minimum partial read : enable this option if you want the software
to generate a barcode value even if a barcode is incomplete. This
may be the case if the end of the barcode is unavailable or of
insufficient quality, etc. If enabled, enter the minimum number of
characters that will be allowed for a partial read. This option is
useful for barcodes that are only used for document or batch
separation where the absolute value is less critical.
Verify checksum : tick this option to make the software
automatically verify the barcode check character(s) - if there are
any.
Separation and Deletion
When a barcode is detected, it can be used to enable the following
options:
- Separate batches
