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57.
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:
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.
