l
Process by: Select to define whether to process the image by page orby file:
l
Process by Page: The task is able to handle single or multiple page files (Tiff and
PDF) and act as a loop to process each page independently and sequentially. The
metadata file will be created separately for each page if it does not exist or will be
enhanced with the values on processed Datapage level if it already exists. All
supported images will be converted to tiff format.
l
Process by File: The task will process the file once and will insert the barcode
information in one metadata file. Metadata will be created if it does not exist or will
be enhanced with the values if it already exists.
l
Replace non-printable character with: Enter a character that will be used as a
replacement for all non-printable characters read from the barcode.Some barcode types
like Data Matrix can store non-printable characters that metadata does not support.
The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).
