Barcode Scan task character replacement option will allow successful barcode reading
of all non-printable characters in a given barcode. The value specified in the Replace
non-printable character with option will be 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 available in the BarcodeBase64_x_value
Metadata field. This option allows only one printable replacement 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 characters)
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
foreground 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 considered 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).
On Error Tab
For a description of the options on the On Error tab see "Using the On Error tab" on page88.
Comments Tab
The Comments tab is common to all tasks. It contains a text area (Task comments) that lets
you write comments about the task. These comments are saved when the dialog is closed with
the OK button, and are displayed in the Task Comments Pane.
Check the option Use as step description to display the text next to the icon of the plugin in
the Process area.
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:
