the barcodes are correctly detected at
configuration stage in the Detect Best

dialog. However, the result of
the barcode recognition after the
document processing is incorrect.
Most of the preprocessing options of the Enhance
barcode detection
group use minimum and
maximum values to make the component recognize
barcodes in several steps: beginning with the
minimum value and finishing with the maximum
value. If at some step the component recognizes a
barcode value, it may stop at this result. At
configuration stage, the component uses the
maximal values of the preprocessing options for
barcode detection. If you want to get the same
recognition results at configuration stage and at
run-time, use equal minimum and maximum values
for the preprocessing options.
The process stops without any messages

Welcome to Professional Image Management
component
Professional Image Management component is a filter component that is primarily used to enhance the
quality and appearance of B/W images.
This component enhances the quality of the scanned or faxed document, by performing operations that
remove imperfections. You can also use the options in this component to split the image in to several
documents based on a pre-defined set of criteria.
Professional Image Management uses Lead Tools Technology for image processing options.
Getting Started
Feature highlights
Major features of this component are:
•
Despeckle
option removes specks from black and white images, such as FAX transmissions or
scanned documents.
•
Deskew
option automatically straighten scanned images.
•
Use Smooth Text
option to smooth out the bumps and fill in the nicks of a black and white image.
•
Dot Removal
option is used to find and remove dots and specks of various sizes. It is similar to the
despeckle option but allows more control as to which dots to remove. Certain images might have
larger dots that would not be removed by the despeckle option.
•
Remove hole punches
option removes hole punch marks from a black and white image, that is
most likely is the result of a scanned document. This will remove “hole” punches that may be
located at either top, bottom, left or right side of the image.
•
Line Removal
option is used to remove horizontal and/or vertical lines in a black and white image.
•
Border Removal
option is used to remove black borders from black and white images, which are
often the result of scanned documents where the paper document is smaller than the resulting
scanned image.
•
Remove Empty Pages
option is used to remove pages that do not have any text or images. Note
that empty does not mean a white page; a completely black page (or any other color) will be
considered empty as well.
•
Split
the original file into multiple files.

Using Image Management component
Use this component to enhance the quality of a scanned or faxed image.
Configuring
Image Processing tab
Use the options in this tab to process the image.
Activating
Check this option to activate the image management configuration.
Deskew
Click the ellipsis button to make skewed scanned or faxed images straight.
Fast Deskew: Select this check box to rotate the image clockwise or counter clockwise.
•
Threshold Angle:
If the original image is skewed by an amount that is between minimum
and
maximum
then the image is rotated. However if the original image skew angle does not fall
between the minimum
and maximum
range, the image is not rotated at all.
•
Document Type:
Different rotation algorithm is applied depending on whether the image is text
only
or text and picture
.
•
Fill Areas Exposed after Rotation:
Select this check box to fill the exposed areas of the rotated
image with black after the deskew operation.
Precision Deskew:
Clear the Fast Deskew check box for more advanced deskew options.
•
Threshold Angle: If the original image is skewed by an amount that is between minimum
and
maximum
then the image is rotated. However if the original image skew angle does not fall
between the minimum
and maximum
range, the image is not rotated at all.
•
Deskew Angle: Rotate the image if the original image is skewed up to this maximum
angle. The
maximum rotation is limited to 45 degrees in either direction.
•
Precision: This parameter lets you control the granularity precision by which the deskew
operation is performed. To improve the quality of deskew operation, set this parameter to a
smaller value. The precision cannot be more than the Deskew Angle.
•
Interpolation When Rotating: Interpolationis an imaging method to increase or decrease the
number of pixels in a digital image. How smoothly images appear without introducing jaggies

depends on the sophistication of the interpolation algorithm. You can chose bilinear, bicubic, or
no interpolation algorithm when rotating the image.
•
Document Type: Different rotation algorithm is applied depending on whether the image is text
only
or text and picture
.
•
Fill Areas Exposed after Rotation: Select this check box to fill the exposed areas of rotated image
with black after the deskew operation.
Despeckle
Check this option to remove undesired dots and speckles from black and white images, such as FAX
transmissions or scanned documents.
Smooth text
Check this option to smooth and fill in patchy black and white images.
Trim Edges
Check this option to trim blank space from the edges of scanned documents. Select the ellipses button
to set the threshold for the Trim edges Options.
Remove dots
Check this option to remove dots and speckles of various sizes. This is similar to the Despeckle
option;
however it allows more control as to which dots to remove. Certain images might have larger dots that
would not be removed by the despeckle option.
Note that there is possibility of removing certain portions of an image if the Maximum dot height and
width are set too high.
Remove hole punches
Use this option to remove hole punch marks from a black and white image. The hole punches can be
located at either top, bottom, left or right of the image. You can tune the maximum hole punch width
and height as required.
The default hole punch location is set to left side of the image.
Remove lines
Use this option to remove unwanted horizontal and/or vertical lines in a black and white image by
specifying the line attributes. The max line width
can be configured to be between 0
and 0.1
inches.

Remove borders
Use this option to remove black borders from black and white images. This occurs often when the
scanned documents is smaller than the resulting scanned image.
Set the parameters for the border removal:
•
White Noise specifies the amount of white noise tolerated when determining the border.
•
Variance specifies the mount of variance tolerated in the border. The value should be higher the
more the border varies in thickness.
•
Border Area specifies the percentage of the page from each edge that is designated as the search
area for borders to remove.
Remove empty pages
Check this option to remove pages that do not have any text or images.
“Empty” does not necessarily mean a completely white page, a completely black page (or any other
color). This option can be used in multi-page tiff files; it does not apply to any of the other supported
formats by the different options of this component.
Remove first pages
Select this option to remove the first page from the image. Note that this option takes precedence over
other options.
Auto binarization
Converts the image into a binary format. The supported file types for the image are PDF and Tiff.
PDF Load Options
Use the same horizontal and vertical
- select this check box to use only one value for both horizontal
and vertical resolutions.
Horizontal resolution (DPI)
and Vertical resolution (DPI)
- these combo boxes allow you to set up
horizontal and vertical resolution of opened files in DPI. You can enter the value manually or select one
of the predefined values: 72, 96, 150, 200, 300, or 600. The default value is 200 DPI for both vertical and
horizontal resolutions.

Color depth (BPP)
- set up color depth of PDF documents manually or select one of the predefined
values: 1, 4, 8, or 24. For example, 24 BPP (bits per pixel) denotes true color images, 1 BPP denotes
black-and-white images. The default value is 24 BPP.
Text anti-aliasing (bits)
- enter the level of text anti-aliasing manually or select one of the predefined
values: 1 (means no anti-aliasing), 2, or 4 (gives maximum anti-aliasing). The default value is 4 bit.
Graphic anti-aliasing (bits)
- enter the level of graphics anti-aliasing manually or select one of the
predefined values: 1 (means no anti-aliasing), 2, or 4 (gives maximum anti-aliasing). The default value is
1 bit.
Split tab
This tab provides several options for splitting an image. Specify the desired type of splitting from the list
below:
•
None
•
Split into specified pages - here the user can specify the number of pages the document is split
into. For example, If the user is scanning batches of 3 pages invoices, the process could receive
one big file containing several invoices. The user can choose to split every 3 pages, having as a
result a single file for each invoice.
•
Split on pages - The user can provide specific page numbers where the document should be split,
you can instruct the component to split the document on a particular page or on several pages in
a comma separated list. If one of the page numbers that the document should split on, does not
exist, the component will just ignore it. If for example the configured process will be receiving
scanned documents that are always formatted in a specific way, and the first 2 pages contain
information that the user wants to store in a separated document, then by choosing this option
and setting the associated parameter to "2", the result will be 2 files, one containing the first 2
pages and other containing the remaining pages.
•
Split on empty page
The split option is used for splitting multi-page tiff files, it does not apply to any of the other supported
formats by the different options of this component.
Runtime Replacement Tag(RRT)
What are RRTs?
Runtime Replacement Tags (RRT) are tags placed within the configuration file for replacement by
metadata values during execution time. At runtime (when a component is executed within the
application), each component is responsible for searching all items within the configuration memory

structure and replacing their assigned RRTs with actual metadata values. The RRTs were formerly
known as Field Value References or FVRs.
RRT naming convention
The figure below provides you with an illustration of the RRT definition. Each part of the RRT is designed
to create a standard field tag replacement that can be expanded to all components designed and
developed within the component framework.
Important Note:
RRT’s are case sensitive. You must follow the proper case for all RRTs. You cannot
introduce space characters in between the RRT segments.
The table below provides details on each segment of the RRT:
Segment
Name
Description
Markers
Special characters used to mark the beginning and the ending of each RRT. The “~” is
used to mark each end. Note that you cannot use the same character anywhere within
the other parts of the RRT. Having “~” appear as a value of a special field is not
supported with this new RRT design.
RRT ID
Special three characters identifying the component owning the RRT and responsible for
replacing the tags with the actual values.
Separators
Double colon “::” characters used to separate the Component RRT ID from the actual
Replacement Tag Name. Double colon is now reserved and cannot be used within other
parts of the RRT. Example of an illegal use of :: is “~MYC::Invoice::Number~” where the
double colon is repeated within the replacement tag name

content source (e.g., device, etc.), or a metadata generated by the component itself
(e.g., XML data field, etc.). The following types of RTN are currently supported:
i.
Reserved (RRTN)
– Each component is allowed to create and maintain a set of
reserved RTN or RRTN. Within the boundaries of each component reserved names
have special meaning. Each component defines a list of RRTNs.
ii.
Field (FRTN)
- Some components that support field names allow the fields to be
referenced using the special enclosure character: “%”. An example of field name
used within RRT is:
~MYC::%Invoice Number%~
This example allows replacement for a field called “Invoice Number” within the
MYC component with the value of the field Invoice Number.
iii.
Special Sets (SSRTN)
- These are special set of characters providing you with
useful information on the job such as document date, document time, etc. It’s
important to note that not all components support the SSRTN values. Look in
documentation for each component to find the components that do support
SSRTNs
How does it work?
When you create a process that consists of a series of components, the components are executed in
order from left to right (Capture to Route). Each component, prior to its termination, searches all
configuration entries and replaces all its own RRTs with actual metadata values. As an example, the XML
Knowledge Package Loader component will search for RRT’s starting with “~ASX::” and replaces them
with actual metadata values.
The order of execution of components within a process is significant. Due to the component execution
order (Capture to Route), RRT’s owned by components that appear later in a process cannot be placed
within components that appear earlier in a process. As an example, placement of Folder Store
component RRT’s within a Capture component such as Poll Directory is invalid and will not be replaced
at runtime.

RemovedPageList Comma-separated list of removed pages.
s.
PageCount
Number of pages in the document.
SplitNumber
Index to the document created as a result of split.
The following example provides a sample usage for your reference:
~PIM::RemovedPageList~
- replaced with comma-separated list of the removed pages.
These RRTNs are normally used in scripts. For example, based on the value that ~PIM::SplitNumber~
returns, the scripts applies a watermark to your document.
Field Replacement Tag Names (FRTN)
This component does not have any FRTNs and replacement of field names with metadata values.
Special Set Replacement Tag Names (SSRTN)
This document does not have any SSRTNs.
Troubleshooting tips
Problem Description
Solution
When using the Line Removal option,
some lines are not removed.
This is caused when there are lines in the image that are wider
than the maximum width specified in the configuration.
Increase the maximum specified width from the component
configuration GUI.
Restrictions and limitations
The following options can only be used in black and white images (1 bit formats):
Smooth text, line removal, hole punches removal, dot removal and border removal.
