found in place of any non-printable character in the BarcodeValue and Barcode_x_Value
Metadata fields, while the original barcode value (i.e. with non-printable characters) will be avail-
able in the BarcodeBase64_x_value Metadata field. This option allows only one printable replace-
ment character. By default, this character is an empty space. Note: Non-printable characters are
the first 32 characters in ASCII character table (Ex.: form-feed, newline, carriage return char-
acters)
l
Scan Interval: Set a scan interval in pixels of image scanning. This property directly affects the
performance and quality of the recognition. A greater interval value means better performance,
but a lower recognition confidence level, and vice versa. For example, a value of 1 means that
every image line will be scanned. By default, the Scan Interval is set to 1.
l
Threshold level [0..255]: Set to represent the color threshold level in order to distinguish fore-
ground pixels from background pixels in color or gray scale images. Value can be between 0 and
255, corresponding to the pixel intensity value, from 0 (black) to 255 (white). Therefore, defining
a threshold value of 128 means that the pixels with an intensity greater than 128 will be con-
sidered as white, while those less than 128 will be considered black. The value 0 means that the
color threshold level will be calculated automatically depending on the image. By default
Threshold level [0..255] is 0. This parameter is ignored with binary images (black and white
images).
Miscellaneous Tab
The Miscellaneous tab is common to all tasks.
Check the option Use as step description to display the text next to the icon of the plugin in the Pro-

Metadata implementation
The Barcode Scan task reads each scanned file and outputs the values read from barcode(s) on the
page(s) into Metadata depending of the selected Process by option:
l
If the selected option is process by page, then the Metadata file is created and overwritten for
each new scanned page.
l
If the selected option is process by file, then only one Metadata file will be created (or updated).
Note: If Metadata was created previously in the process, the task only adds new fields to the
existing Metadata at the datapage level.
Metadata fields
The barcode values are stored at the datapage level of the Metadata. In the following definitions, the
first 2 Metadata fields are for standard use, while the next 8 fields contain '_1_' in their name. This
