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731.
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 initial input task that generates an error will stop the process from
running as a whole, and output tasks will not generate output. The On Error tab can be used to
overwrite the default behaviors.
l Send to Process: Check this option to send the job file to an error management process.
l
Error Process drop-down:Enabled only when the Send to Process option is checked.
Lists any process of which the initial input task is the Input Error Bin task.
l Action:In the initial input tasks, this group is disabled and defaults to Stop Process. In
all other tasks where the On Error tab is present, the following options are available:
l Default:By default, the task is ignored as if it did not exist and the error is logged
before continuing the branch or process; the job file is passed on to the next task in
the process. When an error occurs in a loop (or in a plugin that acts like a loop), the
loop may log the error, terminate the current iteration and proceed with the next
iteration.
