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).

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 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).
