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).
On Error Tab
The On Error tab is common to all tasks. Details can be found in the" Task Properties Dialog" on page666.
By default, any action task, branch, splitter or condition that generates an error will simply be ignored, and
the task just under it (not within a branch)will be given control of the job file without any modification. Any
