Chapter 1
Installation and Setup

In this chapter you will find information on the following topics:

*    System Requirements
*    Installation
*    Setting up your Scanner for Recognita Plus
*    Registration

System Requirements
You need a configuration with at least the following characteristics to install
and run Recognita Plus:

*    IBM compatible PC with Intel Pentium or equivalent processor.
*    Microsoft Windows 95, Windows 98, Windows NT 4.0 or Windows 2000 operating
systems.
*    8 MB of memory (RAM) for Windows 95 and Windows 98 (16 MB recommended),
    16 MB of memory (RAM) for Windows NT 4.0 and Windows 2000 (32 MB
recommended).
*    35 to 45 MB free space on your hard disk, depending on the installation
options you choose. To store your work with Recognita Plus, you need a lot more
space, especially when creating long multi-page documents and having images
embedded in your Recognita Documents.
*    If you want to scan your paper documents, you need a supported scanner
with 300 or 400 dpi resolution. For information on directly supported scanners,
refer to the files SCAN_???.RTF supplied with the program (xxx is a language
dependent part of the file name, it is eng for English, ger for German, etc).
You can access the file contents in your setup language through the shortcut
"Recognita Scanner Drivers" in the Recognita Program Group. More scanner
information is provided on our Web-site www.caere.com/recognita. For information
on scanners accessed through Caere's Scan Manager, use the shortcut to the "Scan
Manager Setup Notes" in the Recognita Program Group. You can use Recognita Plus
without a scanner to process image files.
*    VGA monitor (preferably with more than 256 color support for handling
color images).
*    Mouse or other pointing device.
*    CD-ROM drive at installation time.
Installation
You are guided through the installation with clear instructions at each step.
First, please exit any applications that may be running or were auto-started.

Important: Under Windows NT 4.0 and Windows 2000, you need administrator
privileges to perform installation.

To install Recognita Plus:
1.    Insert Recognita Plus 5.0 CD-ROM in your CD-ROM drive. Wait for
setupocr.exe to start automatically. If it does not start, locate your CD-ROM
drive either in the Windows Explorer or in the Browse dialog box of the Start
Menu's Run command and run setupocr.exe from your CD root.
2.    First, you are prompted to enter the CD-Key. You can find it on the back
of the CD-ROM holder.
3.    Recognita Setup Wizard takes over. Select an installation language and
follow the instructions on screen.
4.    Click on Next at each step of the installation if you have specified the
settings that you were asked or click on Back to change any of the settings
specified at an earlier step.
5.    Click on Finish to complete the installation and have the necessary files
copied to the folder you specified.
6.    After these steps, you have control over the following settings, presented
in a tabbed dialog box:
*    Program languages (i.e. the language used in menus, messages, etc.)
*    Help file languages
*    Text output converters
*    Dictionaries, used for spelling and Language Analysis
*    Direct connection to applications and integration into mailing systems.


Note: During installation Recognita Plus's Maintenance Setup program
will also be added to the Recognita Plus 5.0 program group. You can use it later
to make changes to the current Recognita Plus setup, for example add a new
scanner driver or output text converter, enable a direct connection, etc. An
uninstall facility will also be placed in the group.

Setting up your Scanner for Recognita Plus
Recognita Plus can access scanners in different ways. Using Caere's Scan Manager
is the preferred method, it is set as default during installation.

Scan Manager is a regularly updated software package from Caere Corporation
providing consistent access to a wide and increasing number of scanners. Scan
Manager is automatically installed as the last step of Recognita Plus setup. It
displays a dialog box, offering a list of scanner brands. Use this only if you
want to scan through Scan Manager or set 'No scanner'. The first item in its
list is (Generic). Choose this to set "No scanner" or a generic TWAIN or ISIS
interface. In these last two cases you should check whether the delivery
settings are suitable. To choose a named scanner, click the brand to get a list
of models. Select the one(s) desired. Scan Manager usually accesses the chosen
scanner through TWAIN, but makes all the necessary settings automatically.

Scan Manager's setup program adds an icon to the Windows Control Panel. You
should click that icon to change the installed scanner or any of its settings.

If you do not have a scanner, you can still use Recognita Plus to process image
files scanned by other scanning software or arriving by fax boards and through
E-mail. In this case you must remove Scan Manager from its default position, or
select (Generic)/No scanner.

If you experience scanner difficulties see the next topic "Changing the Scanner
Setup"

Changing the Scanner Setup
Before changing the scanner setup make sure your scanner runs with the software
provided by the scanner manufacturer. During setup please have your scanner
turned on. You can modify your scanner settings by using Recognita Maintenance
Setup.
You can access a scanner by choosing:
*    A specific scanner offered by Caere's Scan Manager program.
*    A generic scanner driver offered by Caere's Scan Manager program.
*    A scanner driver supplied with Recognita Plus.
*    One of the TWAIN drivers supplied with Recognita Plus.

The following scanner setup dialog box is displayed by Recognita Maintenance
Setup:


















Scan Manager appears at the top of the list of Installed Scanner Drivers. It is
automatically placed in the Installed Scanners panel and set as Default. Keep it
there if you wish to use Scan Manager, and specify a scanner in its dialog box
when it appears. If you do not want to use Scan Manager, either remove it or add
one or more Recognita-supplied direct drivers, setting one as the default. The
following topics explain how to setup Recognita scanner drivers in case of
problems with Scan Manager.


To setup your scanner:
1.    Turn on your scanner.
2.    Select the scanner model from the list of the installed scanner drivers.
3.    Click on Install. The driver name appears in the list of the installed
scanners. If you have more scanners connected to your computer, you can install
drivers for all of them in the same way.
4.    A dialog box with the factory default settings of the scanner is
displayed.












    It shows settings such as Port addresses, Interrupt values, Interface
cards, etc. Any grayed items are not needed for the current scanner. Check the
values are correct. Specify whether an automatic document feeder (ADF) or
transparency adapter is attached to the scanner.
5.    Click on Check Scanner Interface to run a check on your configuration, to
see whether all the information supplied is correct. If not, a message will
advise which item needs attention. This might be a needed interface card not
detected, an incorrect port address, etc. If you cannot immediately solve the
problem, continue with setup, then consult the file SCAN_???.RTF to get a list
of all factory default settings and run Maintenance Setup to change the scanner
values as necessary.
6.    Click on OK to return to the main scanner panel.
7.    If you have installed more than one scanner, select one to be used
currently, and click on Set As Default Scanner. You can change the default
scanner later by running Recognita Maintenance Setup.
8.    To remove an installed scanner, select it from the list of the installed
scanners and click on Remove.
Setting up TWAIN Compliant Scanners
TWAIN is a standard interface for image capturing devices. Most scanner
manufacturers provide TWAIN compliant drivers for their scanners.

Recognita Plus has its own scanner specific drivers for many scanner models and
supports TWAIN.

If you have a TWAIN compliant scanner installed on your computer, you can choose
from TWAIN specific entries during installation and when running Recognita
Maintenance Setup. The scanner driver list contains one generic entry for TWAIN:
    TWAIN: Basic Driver
and one or two items for each installed TWAIN compliant scanner in the form:
    TWAIN: <data source name>

Two items are displayed if both 16 and 32 bit data sources have been installed
under Windows 95 or 98. Always select a 32 bit driver if available.

Note: If your TWAIN compliant scanner model's name also appears on the driver
list as a separate item (without the prefix "TWAIN"), you may choose it (and we
recommend this) to be used by Recognita Plus through its own scanner driver.

Choosing a "TWAIN:<data source name>" entry:
The <data source name> contains the product name of the given data source (it is
very often different from the scanner's actual model name). We suggest you
choose this rather than the TWAIN: Basic Driver. If this is chosen, scanner
settings can be set in Recognita Plus's user interface.
Choosing the "TWAIN: Basic Driver" entry:
The TWAIN: Basic Driver should be used only if you have problems with scanning
when using a TWAIN:<data source name> type driver.
If the TWAIN: Basic Driver is chosen, scanner settings can be set on the data
source's own user interface, which appears when scanning is started from
Recognita Plus.
When you complete step 5. or step 6. of setting up your scanner (see page 9), a
Select Source dialog box appears with the list of the installed data sources'
names. These names are identical to the ones in the "TWAIN:<data source name>
type entries, but this time they appear without the prefix "TWAIN". You should
specify here which one you want to use through the Twain Basic driver of
Recognita Plus.

Other TWAIN issues:
The user interface of a TWAIN data source might offer settings unsuitable for
OCR purposes. These can be for example extreme resolution values, halftone
(dithered) image output and so on. Please avoid these for best results.

In some cases Recognita Plus might fall back to using TWAIN: Basic Driver
despite your selection of a TWAIN: <data source name> driver. This is not an
error, and happens if Recognita Plus detects that it cannot control all
necessary scanner settings. Remember that in this case the scanner parameters
can be set on the data source's own user interface.
If you use the TWAIN: Basic Driver, you may try to enable the automatic document
feeder handling mechanism of the data source. To do this, enter the line:

    AdfHandling=1

into the SCANNER.INI file in the Recognita Plus folder. If this works, the data
source's user interface will be displayed before the first page of a stack only.
Otherwise it appears before each page.
Special Scanner Issues under Windows 95 and 98
If you get an error message during scanning under Windows 95 or 98 and it is not
likely that it is a real scanner error, you should insert the following line
into your CONFIG.SYS file right after the HIMEM.SYS and EMM386.EXE entries:

DEVICE=<Recognita path>\RSDBUF.EXE [/8]

where <Recognita path> is the full pathname of Recognita Plus. Note that you
must not use the DEVICEHIGH command in this line. This driver allocates buffers
in the conventional memory for Recognita scanner drivers. If the /8 switch is
given, less memory is allocated (8k).

Do not use the /8 switch for the following scanner types:

*    Ricoh RS632 with ISI-8 interface card
*    Siemens scanners
*    Lightscan 400P
*    Pentax DS6, DS10
*    Mitsubishi MH216CG
*    AVision scanners
*    Dextra Reader
*    Genius FastReader
*    Mouse Systems PB/Reader
*    Targa TS 30n, TS 600C, TS 800C

Chapter 2
Introduction to Recognita Plus
Have you ever been key-bored? Well, if the answer is no, then you are among the
lucky ones, and it is not likely you'll ever be. However, if the answer is yes,
then you probably know how tiresome retyping your printed documents can be. But
why waste your precious time if a solution to this problem is near at hand.

Recognita Plus - as you might already have guessed - is the solution. This
omnifont and multi-lingual OCR software converts your paper documents with the
greatest ease and accuracy into computer editable form. As soon as you begin to
use it, you will be convinced that this software really means the end of an era
- the era of manual retyping.

In this chapter you will find information on the following topics:

*    What is OCR All About?
*    Processing Stages in Recognita Plus
*    The Recognita Document
*    Application and Document Windows
*    The Electronic Online Help
*    What's New Compared to Version 4.0
*    Product Support
What is OCR All About?

Optical Character Recognition is the art or science of scanning printed
documents and making their text content computer editable. The program examines
the incoming shapes and decides which character each represents. Recognita
Plus's technique is mainly based on contour analysis in which each character is
defined by certain typical measurements or ratios of its contour elements. This
has the advantage of making recognition omnifont: much more independent of
character size and font variations. As a supplement to its base algorithm, the
program also uses Self Assertion Technology (SAT) which uses improved pattern
matching. In addition, the OCR engine consults the Language Analysis module of
the recognition language on the words being built from the recognized
characters. These techniques together ensure optimum recognition.

A new level of accuracy is introduced with Recognita Plus 5.0. It is  available
for eleven major European/American languages. The program is equipped with two
recognition engines, both with their own Language Analyst support. The two
engines read texts in parallel and compare results. Where differences arise,
certainty data from both engines are used to accept the best solutions. Tests on
degraded documents have shown the number of errors can be reduced by up to 30%.


Processing Stages in Recognita Plus

People are not the same. Neither are the tasks they have to solve
day-by-day. What they all may need to make their lives easier is a flexible
tool, which can be tailored to their needs.

Recognita Plus is a versatile product which can be used in many ways to process
single-page or multi-page documents. From step-by-step manual interaction to
fully automated document processing, everything is possible. This guide does not
cover all the possibilities but describes the most typical processing steps.
Besides this, it draws your attention to settings that have an effect on how a
document can pass through Recognita Plus. To learn about these settings please
read the relevant topics in the online help of Recognita Plus.
Processing steps in Recognita Plus

1.   Obtaining the source
    This involves getting some input. It can mean scanning to create a
digitized image of the document. It can mean opening an existing image file,
either from Recognita Plus, the Desktop or Explorer, or taking the image
attachment from an e-mail.
    Scanning and image import can be in black-and-white, grayscale or color.
Images are displayed as imported.

2.   Image pre-processing
    The program automatically prepares the acquired image(s) for optimum
recognition by detecting and removing any skew and making sure orientation is
correct. (You can pre-define orientation or leave the program to detect it.).

3.   Decomposition, zoning
    This involves finding information on the page and zoning it. The program
automatically distinguishes graphics from text; text is classed as flowed text
or a table. The program also decides a reading order for the zones.
    Manual zoning is also possible. You can draw zones, modify their size,
position, order and assign a recognition engine. Zone templates can also be
applied.

4.   Recognition
    This is the heart of the operation. Here one or more of the six
recognition engines is used, depending on the zone properties. The engines
available are: Omnifont (most often used), Dot matrix, Checkmark, Barcode,
Braille and Handprint (for numbers only). As a result of the recognition
process, you get a Recognita Document with formatted, editable text. Typically,
the processing stops after this step. If stopped, any page can be re-recognized
with changed settings.
5.   Proofing, training, editing
    These functions make up the correction phase and are controlled fully by
the user. Proofing helps you find any problem areas, such as non-dictionary
words or suspect characters. Training can be used to teach the program
repeatedly misread characters. The built-in editor offers most normal word
processor editing functions for correcting and formatting the text.

6.   Saving and exporting
    You can save the text in a wide range of text formats with a formatting
level of your choice. Images can also be saved in many popular image file
formats. In addition to these, you can also save your work as a Recognita
Document, containing both text and images, ready for further processing. Copying
to the Clipboard and sending mail attachments are also possible. This step can
be either manual or automatic.


The Recognita Document
A Recognita Document (file extension RCD) consists of pages which contain or are
linked to the acquired images of your document and - if recognized - also
contain editable text. Data related to the images and texts on the page are also
stored. This file format is unique to Recognita Plus. Each character or
recognized element is linked to the corresponding part in the original image so
that proofing, verifiers and the training module can function.

Recognita Document files can be saved and later reopened by the program,
providing the basis for deferred processing, that is, for example, doing
scanning one day, recognition the next, full-facility proofing and text saving
on the third or any later day. You should retain your Recognita Document files
as long as you expect that you might want to save some or all of their contents
(either text or images) in an output format Recognita Plus supports.
Application and Document Windows
Recognita Plus can handle more than one document at a time. Recognita Documents
are displayed in document windows in the working area of the main application
window. A typical document window in its maximized state is shown below.




























To get information on the various screen elements, their purpose and usage,
consult the context sensitive help.

a summary of cursor shapes, settings and language lists and a glossary.


What's New Compared to Version 4.0

Recognition
*    Maximum accuracy from dual-engine recognition available for 11 languages.
Two OCR engines read the text in parallel, both using dictionary support. They
compare solutions and confidence levels for real accuracy gains, especially on
degraded documents.
*    Choose from 6 recognition levels, from fastest to most accurate: with one-
, two- or three-step reading, with or without support of a Language Analyst and
single or dual-engine recognition.
*    A new OCR-specific deskew algorithm yields greater accuracy.

Image handling
*    Color and gray images can be scanned, displayed, printed and exported.
Graphics zones in recognized text files can also contain color images. Mixed
image types (black-and-white, gray, color) can now be saved to a single multi-
page image file.
*    A preview feature makes it easier to navigate and find required image
files.

*    The program includes Caere's Scan Manager 5.0, opening the way to much
wider scanner support.

Languages
*    Cyrillic alphabet support is introduced, with ten languages offered:
Bulgarian, Byelorussian, Chechen, Kabardian, Macedonian, Moldavian, Ossetian,
Russian (with dictionary support), Serbian and Ukrainian.
*    The language list can be customized. On delivery, the languages with
dictionary support appear. A second list can be invoked, presenting all 114
supported languages. Languages can be added, removed or reordered as desired.

Proofing and editing
*    The static pop-up verifier can be replaced by a dynamic one which remains
open and tracks the editing position, with the current character always centred
in the pop-up window.
*    The side-by-side verifier is now referred to as the Image pane verifier.
*    The Find facility can be set to find whole-word occurrences only.
*    The decimal separator in tables has become user-definable.

Processing
*    The Stop for (Re)zoning feature can be turned off or on while processing
is paused, allowing the zoning method to be changed midway in a document.
*    A two-page template facility makes it easier to process two-page forms or
books.
*    The Revert to Saved facility remains available for selected pages in the
Browser's context menu, but also appears in the Main menu, where it functions
for the whole document.
*    Improved saving support for exporting recognized texts to MS Word 97.


Improved support for the visually handicapped
Braille recognition
Braille can be set as the General zone type for a whole document. Auto-
decomposition places single whole-page recognition zones. Manual zone drawing is
possible, but all zones in the document must be for Braille recognition;
numbers-only zones are permitted. Output will be the editable text equivalent of
the Braille text.

General modifications
The Text, Image and Browser panes can be maximized by Ctrl+1, Ctrl+2, Ctrl+3
respectively. Ctrl+4 restores the current pane. The focus can be moved from one
pane to the next by F6 and toggled between the Browser's list and pages by Tab.
When a single page is selected in the Browser list, F2 allows text entry into
the Note field. Training suggestions can receive the focus, making them
available to screen readers. Direct connections can be activated by Hot Keys.

Specific modifications
The following modifications can be invoked by starting Recognita Plus from a
command line with the /blind option: In the View/Columns dialog box, checkmarks
are replaced by YES/NO texts. Edit box displays use Windows Code Page
characters, not Recognita Fixed Fonts. The six-position Speed/Accuracy slider in
the Options/Accuracy panel is replaced by a drop-down listing. That means all
these controls can be handled by a screen reader.

Chapter 3
Processing Documents
This chapter provides information on processing your documents with Recognita
Plus. There are different ways to scan, recognize, correct and save a document.
Depending on the quality and number of pages to be processed, the time you
intend to spend on the work, the required accuracy and the preferred proofing
method, you may choose from many different possibilities. You can control the
processing stages step-by-step or choose fully automatic processing.

In this chapter you will find information on the following topics:
*    Overview of Processing
*    Creating Documents
*    Interrupting and Continuing the Process
*    Recognizing Images in a Document
*    Working with Documents
*    Saving Documents, Text and Images
*    Starting Recognition from Other Applications
*    Processing and Saving without Display
Overview of Processing
The following diagram tries to summarize the main processing steps available in
Recognita Plus.
























The process stops (or can be stopped) at the points indicated and the program
allows different user interactions. Re-recognition of images with modified
settings is possible. You can also save the current state of the document to a
Recognita Document file at any time. Re-opening it later is the key to deferred
processing.

In addition to the possibilities shown above, Recognita Plus offers the unique
feature Save Without Display. If it is enabled, the program processes scanned
pages or image files and saves the results (images, text or Recognita Documents)
fully automatically to a series of output files without user interaction.
Creating Documents
You can use the sample files shipped with Recognita Plus for the procedures
starting from image files. To scan printed documents please choose some and have
them near your scanner.

Note that there is no such a thing as an empty Recognita Document. A new
document is always created by scanning printed materials or loading image files,
and - if required - recognizing their contents. In general, images can be
embedded in a Recognita Document file; image files can also be linked by path
and name.

There are two basic methods of scanning/loading images:
*    Scanning/loading and recognizing. This method results in a document with
images and text.
*    Scanning/loading only. This method results in a document with images only.
Recognition can be carried out later.

When a process is started and there is at least one document open, the Next
Document dialog box appears:








*    Choose one of the first two options if you want to add the new pages to
the active document.
*    Choose one of the other two options if you want to create a new document.
If you choose the last one, the Options dialog box will be offered to allow the
new settings to be specified.

To load (and optionally recognize) image files:
1.    If you want to use the toolbar to start processing, make sure the selected
image source is file and not scanner. You can toggle between the two by clicking
the leftmost button on the Main toolbar.
2.    Start loading files with or without recognition.
    With recognition:
    *    Make sure the main processing button shows the image on the
    left and click on it or
    *    Choose Read>from File in the Process menu.
    Without recognition:
    *    Make sure the main processing button shows the image on the
        left and click on it or
    *    Choose Scan>from File in the Process menu.

The File(s) to Open dialog box appears.

















It will show the last used folder location. Select the files you want to
recognize. Selected files plus files listed in the lower panel will be
processed. Whenever a single file is selected in either panel, click Show... to
see a quick preview image of the file.

Click Add to add the selected files to the list in the lower panel if you want:
*    to process files from different folders
*    to process the files in a specific order
3.    Choose OK to start processing the files. Progress is indicated on the
status bar. If recognition was selected, the progress of the OCR process is also
indicated in an overview window showing the image.
4.    At the end of the process, the first page processed will be shown.

To scan (and optionally recognize) paper documents:
1.    If you want to use the toolbar to start processing, make sure the selected
image source is scanner and not file. You can toggle between the two by clicking
the leftmost button on the Main toolbar.
2.    Place the page(s) to be scanned in your scanner. You can scan a stack of
pages in one process if you have an automatic document feeder (ADF).
3.    Start scanning with or without recognition.
    With recognition:
*    Make sure the main processing button shows the image on the left and click
on it or
*    Choose Read>from Scanner in the Process menu.
    Without recognition:
*    Make sure the main processing button shows the image on the left and click
on it or
*    Choose Scan>from Scanner in the Process menu.
4.    Wait for the pages to be scanned in and processed. Progress is indicated
on the status bar. If recognition was selected, the progress of the OCR process
is also indicated in an overview window of the original image.
5.    When no more pages are available, a dialog box appears, asking you if you
want to scan more pages. Choose YES if you want to scan more pages into the same
document or NO if you want to stop the process. Place the new page(s) into the
scanner before choosing YES.
6.    At the end of the process, the first page processed will be shown.

Interrupting and Continuing the Process
You can check, modify or draw zones during processing of a multi-page document
by making the program stop when desired. When the process is interrupted, the
image of the page being processed will be displayed. You can modify/draw zones
and change settings not disabled at this time. After checking, modifying or
drawing zones you can re-start the processing of the page or abandon the whole
process, leaving the last page unrecognized.

See the topics "Working with Zones" and "Working with Table Zones" in Chapter 4
for more information on zoning.


To preset the program to stop after each image is
scanned/loaded:
*    Press the Stop for (re-)zoning button in the Main toolbar or
*    Choose Stop for (re-)zoning in the Process menu.
The state of this button can be changed while processing is interrupted.


To stop the process during recognition:
*    Click on the Interrupt button in the Main toolbar (available during
processing only).


To re-start processing:
*    Click on the Continue button in the Main toolbar (available in interrupted
state only) or
*    Choose Continue in the Process menu.


To abandon processing:
*    Click on the Stop button in the Main toolbar (available in interrupted
state only) or
*    Choose Stop in the Process menu.

    All previous pages will remain, the current page will be unrecognized, but
its image will remain. No further pages will be processed.
Recognizing Images in a Document
Some reasons why images in a Recognita Document might need to be (re-
)recognized:
*    They were originally loaded without recognition, because manual zoning was
required.
*    The recognition results are not satisfactory because of a wrong setting
(for example language, dictionary, brightness, etc.).
*    The recognition results are wrong because of improper zone positions/types
or incorrect image orientation, etc.
You can (re-)recognize:
*    The image on the current page
*    All the images
*    All unrecognized page images
*    Images on selected pages

To recognize the image of the current page:
*    Make sure the multi-state button on the Editing toolbar shows the image
shown here and click on it or
*    Choose Recognize>This Page in the context menu of the image pane.

To recognize all page images:
*    Make sure the multi-state button on the Editing toolbar shows the image
shown here and click on it or
*    Choose Recognize>All Pages in the context menu of the image pane.

To recognize the unrecognized page images:
*    Make sure the multi-state button on the Editing toolbar shows the image
shown and click on it or
*    Choose Recognize>Unrecognized Pages in the context menu of the image pane.

To recognize images on selected pages:
1.    Select the page(s) to be recognized from the Browser List.
2.    Choose Recognize Page(s) in the Browser's context menu.
Working with Documents
After a document has been created, you can further process it in different ways,
depending on its contents, your goals and working method. This section gives an
overview of the possibilities.
Creating output (see later in this chapter):
*    Save or send the document. You can open and work on it later.
*    Save or send some or all of the recognized text in a format you choose.
*    Save or send some or all of the images in a format you choose.
*    Drag-and-drop text and/or graphics to other applications.
*    Print text and/or images.
Revising the recognized text (see Chapter 4):
*    Check and edit the text manually.
*    Start proofing to find and correct problem places in the text.
*    Train characters if necessary.
Zoning for (re-)recognition (see Chapter 4):
*    Check automatic zones; correct them if necessary.
*    Draw zones manually.
*    Load zone templates.
Recognizing images (see the previous section in this chapter):
*    (Re-)recognize some or all of the images in the document.
Adding new pages (see the first section in this chapter):
*    Add new pages to any part of the document.

This guide also presents a separate chapter, "Working with Documents" which
details some of these topics. You can also find detailed information on these
topics in the online help.
Saving Documents, Text and Images
After a document is created, you can save its text and images and/or save the
document as a Recognita Document file. You can also send text, images and
Recognita Documents by electronic mail.
This section describes the following procedures:
*    Saving and Sending Documents
*    Saving and Sending Text
*    Using Advanced Settings for Text Output
*    Saving and Sending Page Images
*    Using Drag-and-drop and the Clipboard
Saving and Sending Documents
Unless you are going to complete your processing very quickly, you should
explicitly save your Recognita Document files (also known as RCD files) shortly
after creation. Then they are available in later sessions with all their
proofing and training facilities. You can also send your RCD files by electronic
mail.

To save a document:
1.    Click on the Save Recognita Document button in the Main toolbar or choose
Save as Recognita Document from the File menu. The first time a document is
saved, the Save as Recognita Document dialog box appears. Choose a location and
name for your RCD file and click on Save.
2.    Click on the Save Recognita Document button regularly as you work to
protect your current changes. The recognized text can be reverted to its last
saved state.

To revert text to its last saved state:
1.    Select pages from the Browser List whose text you want to revert.
2.    Choose Revert to Saved from the context menu of the Browser.
3.    To revert a whole document, use the command in the File menu.

To send a document as a mail attachment:
*    Choose Send>Recognita Document from the File menu. Your mail application
will be activated with a new empty message containing the document as an
attachment.
Saving and Sending Text
After recognition, your Recognita Document contains recognized text. You can
save or send it in any of the different output formats supported by Recognita
Plus. The formats can be chosen from the Format list of the Save Text(s) and
Send Text(s) dialog boxes.
Output formats can be ranked in four groups:
*    Text only formats. These include various GWP and ASCII formats, which
differ merely in how the original formatting is preserved by line breaks, tabs
and spaces.
*    Table and spreadsheet compatible formats. Among these you can find
tab/comma/quote separated ASCII formats as well as formats for the most popular
spreadsheet programs.
*    Word processor formats to which Recognita Plus can convert text fully
formatted, preserving page layout and including graphics.
*    Word processor formats to which Recognita Plus can convert text formatting
attributes but maybe not graphics.
Knowing your word processor, DTP or spreadsheet program, you can decide which
text format is the most suitable for it.

To save recognized text:
1.    Choose Save Text As from the File menu or Save Text from the context menu
of the Browser. The Save Text(s) dialog box appears.

2.    Choose an output format from the Format list.
3.    Set Advanced settings if necessary (see next section).
4.    Select folder location, enter file name and click on OK.

To send recognized text as a mail attachment:
1.    Choose Send>Text from the File menu. The Send Text by Mail dialog box
appears.
2.    Choose an output format from the Format list.
3.    The Advanced option is also available for sending (see next section).
4.    Choose OK. Your mail application will be activated with a new message
containing the text as an attachment.
Using Advanced Settings for Text Output
In addition to choosing a suitable output format, you can have a high degree of
control over the way your text document's formatting attributes will be
preserved. Click Advanced when saving or sending text to display the Advanced
Parameters for Saving tabbed dialog box.

First, you may choose one of three format levels, which correspond to the three
main view modes of the built-in editor of Recognita Plus. These format levels
are:
*    Full format: preserves original page layout; formatted text and graphics
are placed in frames.
*    Part format: preserves character and paragraph formatting. Text is
decolumnized.
*    Drop format: preserves text without formatting. Text is decolumnized
whenever possible.
Each of these three levels has its own set of remembered settings for document,
paragraph and character formatting. Though default values are suitable for most
tasks, customizing them may be useful. In full format, many settings are
compulsorily Auto, in drop format many are not available. Part format is best
for customizing settings.
By default, certain pages are offered for saving and sending. You can select
other pages on the General tab.
*    If you call saving from the File menu, all pages are offered.
*    Using the context menu, the pages selected there will be offered.
You can save each page to a new file by setting the One File per Page option on
the General tab.
Saving and Sending Page Images
Scanned images are always embedded in a Recognita Document file; image files can
be embedded or simply linked by paths to avoid duplication of the images on your
disk. This latter option can be set on the Image tab of the Options dialog box.
No matter which is the case, images can be saved to a supported file format. You
can also send images by electronic mail.

You can create single or multi-page image files of black-and-white or gray or
color images. Images are saved as displayed. The combinations are summed up in a
table in the online help.

To save page images:
1.    Choose Save Image As from the File menu or Save Image from the context
menu of the Browser.
    The Save Image(s) dialog box appears.









2.    Choose an output format from the Format list.
3.    If necessary, choose Advanced>> to specify the pages to be saved and the
One File per Page option.
4.    Select folder location, enter file name and click on OK.

To send page images as a mail attachment:
1.    Choose Send>Image from the File menu. The Send Image by Mail dialog box
appears.
2.    Choose an output format from the Format list.
3.    Advanced settings except One File per Page are also available.
4.    Choose OK. Your mail application will be activated with a new message
containing the image as an attachment.
If you choose more than one page, they will all be placed in one multi-page
image file. If you have chosen a single-page format, you must send each page
separately.
By default, certain pages are offered for saving and sending. You can select
other pages in both dialog boxes.
*    If you call saving from the File menu, the current page is offered.
*    Using the context menu, the pages selected there will be offered.
Using Drag-and-drop and the Clipboard
You can select certain parts of a Recognita Document for drag-and-dropping or
copying to the Clipboard.
In the text pane you can select the following items for transferring:
*    A part of the text, recognized within one zone. Use standard selection
methods to select text.
*    All the text on the current page. Choose Select Page from the context menu
of the text pane or Select Text of Page from the Edit menu.
*    All the text in the document. Choose Select Text of All Pages from the
Edit menu.
*    Graphics in a frame in the text pane. Double-click in a frame containing
graphics to select it. You should switch to full format view to do this. (See
the section "Editing" in Chapter 4 on the three view modes in the editor.)
In the image pane, you can select any zone by double-clicking in it. The
contents of the selected zone will be transferred as image.


Starting Recognition from Other Applications
Recognita Plus can be integrated into your computing environment in various
ways. The following methods are provided:
*    Direct Connection to Applications
*    Recognition Tools in Mail Applications
*    Explorer Context Menu Support
*    Drag-and-drop from the Explorer.
The first two can be enabled during installation or by running the Maintenance
Setup of Recognita Plus. The last one is added automatically.
Direct Connection to Applications
This is enabled in Maintenance Setup, and lets you call up Recognita Plus from
the taskbar any time you are working in another application. The recognized text
will be placed at the cursor position.
To use a direct connection:
1.    Start your target application, and place the insertion point at the
location where you want the recognized text to be placed.
2.    Click on the Recognita Plus direct connection icon on the taskbar. You
will get a menu with two items.






3.    Choose Recognize from File or Recognize from Scanner from this menu. If
Recognita Plus is not running it will be started.
4.    The recognition process will start according to the menu item selected.
The Recognita Plus window will occupy the lower part of the screen.
5.    At the end of recognition, text will be placed at the insertion point. The
part format level is used for text conversion.
Right-clicking on the direct connection icon displays a menu to activate the
Recognita Plus Options dialog box.

To run recognition in the background:
1.    Iconize Recognita Plus after the recognition process is started. The
number of the page being recognized will be displayed in the Recognita Plus icon
on the taskbar.
2.    A flashing icon indicates that recognition is finished. Click on the icon
to activate the Recognita Plus window.
3.    A message box will be displayed asking you to place the insertion point
for text insertion.
4.    Only after placing the insertion point should you choose OK in the message
box.
    Using background recognition allows you to work on your document while
recognition is running. You can even create a new document in the very moment
you are prompted to place the insertion point.
Recognition Tools in Mail Applications
You can use Recognita Plus to read image attachments to messages arriving in
your mailing system. A new submenu, Recognita OCR Tools is added to the menu
structure of your mailing system. The following applications are supported:
*    Microsoft Exchange
*    Microsoft Outlook
*    Lotus Notes
You have two basic ways of doing the recognition:
*    Reading interactively: this starts Recognita Plus (if necessary); the
program recognizes all attachment(s) and places the result in a Recognita
Document, ready for proofing and saving.
*    Reading non-interactively: This runs in the background, and re-directs the
recognition results back into the messaging system as RTF file attachments or as
body text, for example for forwarding or replying.
An example of the Recognita OCR Tools Menu:



Explorer Context Menu Support
The menu item Recognize is added to the context menu of the Explorer (available
also on the desktop), if the selected item is an image file of the following
types: TIF, BMP, PCX, AWD.

To use the context menu of the Explorer:
1.    Select image files in the Explorer or on the desktop.
2.    Choose Recognize. It starts Recognita Plus (if necessary). Recognita Plus
displays the Options dialog box. Change settings if necessary.
3.    Click on OK. The recognition starts. Wait for the process to be completed.
4.    At the end, the Save Text As dialog box is displayed. Use it to save the
recognized text. Recognita Plus remains active.
Drag-and-drop from the Explorer
You can drag-and-drop selected image files onto the icon or the application
window of Recognita Plus; it will start, if necessary. The contents of the image
files will be recognized just as if they had been opened from inside the
program.



Processing and Saving without Display
You can scan or load images, process their contents and save the result so that
documents will not be displayed on-screen, but rather saved automatically to one
or more output files of the specified type. This method is called Save without
Display. Typically you will use this for high-volume jobs. You can use it to
save images, text or Recognita Documents.

To set the Save without Display mode:
*    Choose Save without Display from the Process menu. The two possible icons
of the Process tool are changed to indicate this special working mode.
    The tool with recognition changes as shown:

    The tool without recognition changes as shown:

    To turn this mode off, click on the menu item again.
To use the Save without Display mode:
1.    Set this processing mode as already described.
2.    Start processing as you normally would. A dialog box, similar to the Save
Text(s) or Save Image(s) dialog appears.
    Important: in this dialog box, you specify saving options! Do not confuse
it with the Files(s) to Open dialog box. The latter is displayed after this, if
you asked to load image files.
3.    Specify location, name and other saving options for your output file(s).
*    If you start the process with recognition, you can choose a text format or
Recognita Document.
*    If you start the process without recognition, you can choose an image
format or Recognita Document.
4.    If you want to distribute the incoming pages to more than one file, click
Options to come up on the Document tab, where you can set the conditions to
start a new document, and make other settings.







5.    Choose OK. If you asked to process image files, the File(s) to Open dialog
box will also be displayed. Output files will be generated automatically,
according to the specified settings.
    The output files will be given the specified file name plus a four-digit
number, starting from 0001 by default. You can enter a different starting number
following the file name, enclosed in square brackets. Leading zeros can be
omitted. E.g. to start numbering from 200, enter a file name as shown below:
        sample[200]
    The default extension of the chosen file type will be added at saving
time.
Chapter 4
Working with Documents
Recognita Plus has many features that allow you to further process the documents
you created. Which of these possibilities you will use and whether you use them
at all depends on you and the complexity of the task you have to accomplish.

In this chapter you will find information on the following topics:
*    Working with Zones
*    Working with Table Zones
*    Correcting the Text
*    Navigating in Recognita Documents
*    Using the Character Map
Working with Zones
Zones are rectangular areas enclosing printed elements in an image. They
identify the parts of the page as text or other elements to be recognized or as
graphics to be retained without recognition. Any part of an image outside zones
is ignored during recognition. Zones and their reading order are displayed over
the images. There is always one and only one active zone on a page; it has
handles at each corner and on each side allowing you to re-size it. You activate
a zone by clicking inside it.
After scanning or loading an image, the program analyses the page layout, finds
text and graphics and creates zones. The program also decides a reading order
for the zones.
Zones can also be created manually or by loading a zone template. You can draw
new zones or modify the existing ones.
There are six zone types, indicating which recognition engine will run in the
zone (typically and most often the Omnifont engine). In zones containing text,
distinction is made between flowed text and table zones, also between Language
Set (full alphabet) and Numbers Only recognition. All together, these elements
form the zone properties.
This section contains the following topics about working with zones:
*    Automatic vs. Manual Zoning
*    Basics of Manual Zoning
*    Basics of Zone Properties
*    Basics of Zone Templates.
Automatic vs. Manual Zoning
You may want to disable automatic zoning if you want to recognize only a certain
part of your document or the layout of your document is very complicated and you
suspect or find that automatic zoning is unsuitable.
*    To disable automatic zoning select the setting Disable De-composition at
Scanning on the Preprocessing tab of the Options dialog box.
Basics of Manual Zoning
Zone handling is available through the toolbar and the context menu of the image
pane. This topic describes zoning using the toolbar.

To create zones manually:
*    Click in the image to get a crosshair cursor. Drag the mouse to draw a
rectangular box.

To resize and move zones:




Toolbar buttons for zoning:




To modify zone order:
1.    To start reordering choose the Reorder Zones tool or menu item.
2.    Click in the last correct zone, then click the zones in the desired
reading order. Stop as soon as the order is correct.
3.    Click the Reorder zones tool again or click outside any zone to finish
reordering. Press Esc to abandon reordering.

To delete a single zone:
*    Press Del to delete the active zone.

To delete a series of zones:
*    Press Ctrl+Del to delete the active zone plus all zones following it.
*    Press Ctrl+Shift+Del to delete the active zone plus all zones preceding
it.
Basics of Zone Properties
The default settings are suitable for the most common recognition tasks and
typically you should not need to change zone properties.
Zones have the following properties:
*    One of six recognition engines or graphics
*    Text flow: flowed or tabular, only for Omnifont, Dot matrix and
Handprinted numbers
*    Enabled characters: Numbers Only or Language Set (full alphabet), only for
Omnifont, Braille and Dot matrix recognition engines.
The properties are represented by icons and border coloring. To display icons
set Show Properties in the View tab of the Options dialog box.




Graphics zones have black borders with gray cross-hatching, without icons.





Whether a zone is created automatically or manually, it is first given
properties automatically (see later in this section). You can then change any
property of an existing zone individually if necessary.
You can set the general zone properties to be applied in future decomposition in
the Options toolbar or on the Accuracy tab in the Options dialog box.

To set properties of a zone individually, open the Zone Properties toolbox or
use the context menu of the image pane. The active zone's current properties are
framed thick. Click a different option to apply it to the active zone.









How zone properties are set by the program:
*    Graphics are always detected automatically.
*    Recognition engine:
*    Decomposed zones take the general setting. If it is set to Automatic, then
one of the Omnifont, Dot matrix, Handprint (numbers) or Barcode engines will be
chosen, depending on the zone contents detected.
*    Manual zones inherit the setting of the active zone. When the first zone
is drawn it takes the general setting, or Omnifont if Automatic is set.
*    Enabled characters (applies for Omnifont and Dot matrix):
*    Decomposed zones take the general setting.
*    Manual zones inherit the setting of the active zone.
*    Flowing or table text is detected automatically. To disable automatic
table detection, press Ctrl and hold down while drawing a zone.
*    Braille can be set as the General zone type for a whole document. All
existing zones change to Braille zones with red borders (tables are not
supported). Manual zone drawing is possible, but all zones in the document must
be for Braille; the Language Set/Numbers Only choice remains available. Auto-
decomposition places single whole-page Braille zones. Output will be the
editable text equivalent of the Braille text. See online help for a list of
scanners found suitable for scanning Braille.
Basics of Zone Templates
A zone template file contains information on a set of pre-defined zones (size,
location, properties and recognition order) for a single page. Zones can be
saved to a template file and loaded whenever needed. You can unload a template,
for instance if a wrong one is loaded by mistake.

Zone templates are useful if you want to read many pages or documents with the
same page layout. If a template is loaded, automatic decomposition will not be
done on new incoming images.
The program will correct a certain level of mis-alignment of template zones
which may result from slight displacement of scanned pages.
Right-clicking on the Template field in the Status bar displays a context menu
with template-related commands.

To create a template file:
1.    Draw or check the zones and set their properties if necessary.
2.    Choose Template>Save from the File menu or Save from the context menu. The
Save Template dialog box appears.
3.    Enter the name for the template file and choose Save.

To load a template file:
1.    Choose Template>Load from the File menu or Load template from the context
menu. The Load Template dialog box appears.
2.    Select the template file to be loaded and choose Load. If a document is
open, the Apply template dialog box appears:










3.    Choose one of the three options to apply the template to the desired
pages. If the template is loaded on the current or all existing pages, any zones
will be removed from them and the template zones will be displayed immediately.
If there is no document open, the loaded template will be applied to new
incoming pages.

To unload a template file:
1.    Choose Template>No template from the File menu or No template from the
context-menu.
2.    If the template is going to be unloaded from an open document, the Remove
Template dialog box appears:






3.    Choose one of the two options as desired. If the first one is chosen, all
templated zones will be removed from all pages of the document in which no zone
editing has been done. To remove a template from the current page only, just
edit or delete the zones.
    If there is no document open, new incoming pages will be decomposed, if
enabled.

    Two-page templates are now available for handling two-page forms or books.
These templates conserve two zone patterns and apply them to consecutive pages.
To save a two-page template, prepare the zones on two consecutive pages, make
the first one active, choose Template Save and check the two-page option.

Working with Table Zones

The page layout decomposition automatically distinguishes between flowed text
and tables. If a table is detected, the text image is enclosed in a table zone.
Tables are also auto-detected when drawing a zone manually unless the Ctrl key
is pressed. Tables are indicated by a blue grid over the image.

To toggle between a flowed text (red border) and table zone (blue border), click
on the Zone Properties tool midway on the Editing toolbar. This also serves to
show the properties of the active zone.

In a table, horizontal gridlines always extend over the full width of the table
and can't be shortened. Vertical gridlines do not always extend over the full
height of a table:






You can edit the gridlines within an active table zone. You do this in the image
pane before performing (re-)recognition.
Hints on table editing:
*    By default grid snapping is on, making it easier to join vertical lines
which do not extend over the full height of the zone. Press Alt or both mouse
buttons to enable smooth movement.
*    The Ctrl key restricts moving, insertion and deletion of vertical
gridlines to the current row.
*    If the Ctrl key remains pressed, you can drag the mouse across
neighbouring rows to extend insertion and deletion.
*    You cannot insert gridlines too close to an existing one. These situations
are indicated by prohibiting cursors.
Table editing can be done through the Editing toolbar or the context menu of the
image pane. Table zones must be activated before any table gridline editing. You
can activate a zone by clicking inside it.
Toolbar buttons for table editing:





To move gridlines:
*    You can catch a gridline by the cursor and drag it to a different
position.





To insert gridlines:
1.    Click on the Insert Columns or Insert Rows tool or use the context menu to
get the insertion cursor.
2.    Move the insertion cursor to the desired location and click to insert a
gridline. Repeat as desired. Press Tab to toggle between the horizontal and
vertical cursor.






3.    To return to a normal cursor, click outside any zone or press Esc.

To delete gridlines:
1.    Click on the Delete Rows/Columns or use the context menu to get the
deletion cursor.



2.    To return to a normal cursor, click outside the table zone or press Esc.
To delete all the gridlines:
*    Click on the Delete all Rows and Columns in the Editing toolbar or use the
context menu. This deletes all gridlines in the currently active table zone. The
zone preserves its table property; you can then draw your own gridlines.



Correcting the Text
After recognition, the recognized text stored in the Recognita Document is
displayed in the text pane. Besides normal recognized characters you may see the
following coloured items:
*    Suspect characters: characters marked during OCR as unsure appear
highlighted yellow.
*    Non-dictionary words: words not found in the dictionary appear highlighted
green, provided the main recognition language has a Language Analysis module and
it was enabled. The highlight is removed if such a word is changed or stopped on
without change during proofing.
*    Reject characters: characters the program couldn't identify are
represented by red tildes ( ~ ).
*    Missing characters (rare): ones not in the code page selected
automatically by Recognita Plus appear in magenta. This may happen only if more
than one language was enabled and none of your standard Windows code pages can
cover all their characters.
*    Trained characters: characters changed by training appear in blue. They
become coloured during training.
To find and correct these, you don't have to rely solely on your eyes; you are
also assisted by some tools in Recognita Plus. These are:
*    Internal editor complying with standard editing techniques
*    Verifiers to compare text and its associated image
*    Proofing tool to find problem characters and words
*    User dictionaries for proofing
*    Training misrecognized characters.
Suspect character and non-dictionary word marking are removed when a word is
changed during proofing or typing.
Editing
Recognita Plus comes with an internal WYSIWYG editor having both traditional and
OCR-specific features. It is able to display the text and its formatting
attributes identified by the OCR engine. It has three main view modes plus a
fourth special one. These are:
*    Full format: this mode shows the original page layout; both formatted text
and graphics are displayed in frames.
*    Part format: this mode displays character and paragraph formatting only.
Text is displayed decolumnized.
*    Drop format: this mode displays the text without formatting.
*    Draft mode (rarely used): This mode uses a monospaced font of Recognita
Plus for unformatted text display. It can simultaneously display all characters
Recognita Plus is capable of recognizing. This may be useful for text display if
the fonts required are not installed on your Windows 95 or 98.

To display the text in full, part or drop format:
*    Click on the appropriate button at the bottom left of the text pane or
*    Choose Text Format>Full (Part or Drop) from the View menu.

To display the text in draft mode:
*    Choose Draft Mode from the View menu.

To display the text in different magnifications:
*    Choose the desired percentage from the View menu or from the context menu
of the text pane.

To make changes to the text:
*    Most standard text editing techniques are supported. You can use cut, copy
and paste as well as drag-and-drop to edit text.
*    Use the Editing toolbar to change character formatting.
*    Use the Editing toolbar and the ruler to format paragraphs.
As a rule, you should proof and do any training on the recognized text before
doing general editing; the link between text and image may not work on edited
characters.
Editing Tables
Once a table zone has been recognized, you can edit both the grid and the
contents in the text pane. Recognita Plus respects normal table editing
conventions. The following picture contains a summary of cell selection and
gridline moving methods:


















By dragging the mouse you can expand the selection to neighboring rows, columns
and cells. Use the context menu of the text pane to do cell editing:
*    Use Split Cells to split all selected cells in two. This can be used to
insert an empty column to the right of a selected column.
*    Use Merge Cells to merge all selected cells within a row.
*    Use Insert Rows to insert empty rows before the selected rows. As many
rows will be inserted as were selected.
*    Use Delete Rows to delete the selected rows.
Other editing hints:
*    To insert a new row at the bottom of the table, click in the bottom right
cell and press Tab.
*    To place a tab inside a cell, use Ctrl+Tab.
*    Press Del to delete the contents of the selected cells.
Verifiers
Recognita Plus links recognized characters to their original image. Verifiers
display these images to make correcting the text easier. Enable or disable the
verifiers on the View tab of the Options dialog box. The image pane verifier can
be enabled together with either the pop-up or the dynamic verifier.

Pop-up verifier:
*    Double-click on a character to be checked in the text pane. The image of
the clicked character or space will be centred and shown red in a verifier
window. Click anywhere to close the window.

Dynamic verifier:
*    Click in text to open this. Its display is the same as the pop-up
verifier, but it remains open, tracking the editing position.

Image pane verifier:
*    The image of a clicked text pane character is framed blue in the image
pane. The image tracks the editing position. Change the image pane magnification
to see more or less context.

    The picture below shows two verifiers activated:
Proofing
Recognita Plus has a special find-and-replace tool for proofing the recognized
text. It can help you to find and replace:
*    Suspect characters (highlighted yellow)
*    Non-dictionary words flagged during recognition (highlighted green)
*    Any non-dictionary word found during proofing
*    Reject characters (red tilde by default)
*    Characters changed by training (blue)
*    User defined character strings (e.g. frequently misrecognized character-
pairs).
The proofing language and the different stopping conditions can be set on the
Proofing tab of the Options dialog box. By default, the proofing language is the
same as the one used for recognition. It can be changed before or during
proofing, for example for different sections of a multi-lingual document.
When the proofing process reaches the end of a page and the next page is loaded,
the corrected page will be marked as proofed. This is indicated by a checkmark
in the Proofed column of the Browser. Once a page is marked as proofed, it will
be skipped during future proofing. You can toggle the proofed flag manually by
choosing Toggle Proofed Flag from the context menu of the Browser. If the
proofed flag is turned on again, the suspect character and non-dictionary
markings are displayed and you can proof the page again.

To start (and also to stop) proofing:
*    Click on the Proof tool in the Main toolbar or choose Proof from the Edit
menu.
The proofing dialog bar appears at the bottom of the text pane.

To find a problem place in the text:
*    Click on Find Next in the proofing dialog bar.
    If enabled, the verifiers are automatically activated on found items.












To correct found words using the proofing dialog bar:
*    Select a suggestion from the dropdown list and click on Change (this
option is available if a proofing language is selected) or
*    Enter your correction in the Change To field and click on Change or
*    Click on Add to add the selected suggestion or corrected word to the user
dictionary. For more information on user dictionaries see the topic "User
Dictionaries" later in this chapter.
*    Click on Training to train the found item. For details on training, see
the topic "Training characters" later in this chapter.
You can choose Change All instead of Change to replace all occurrences of a non-
dictionary word or a string with its correction, throughout your whole document.

To correct found words using the editor:
*    Press Esc when a word is found to move the insertion point from the
proofing bar to the word in the text pane for editing there. Press Esc twice if
the dropdown list with suggestions is open.

To get suggestions on any word in the editor:
1.    Start proofing.
2.    Select the word in the editor on which you want to get suggestions. The
Add button will change to Suggest.
3.    Click on Suggest to get suggestions.
User Dictionaries
In addition to the main dictionary that can be used by the recognition and
proofing processes, you can create user dictionaries by adding words during
proofing.
User dictionaries can be saved for future use and one can be loaded per document
whenever needed. If no user dictionary is loaded, words added will be stored in
memory until saved. Loaded and new dictionary information will be used by both
recognition and proofing. The name and status of the currently loaded user
dictionary is displayed in the status bar.
Right-clicking on the User dictionary field in the Status bar displays a context
menu with dictionary-related commands.

To edit a user dictionary:
1.    Load the user dictionary. (You can also edit dictionary words added during
proofing and not yet saved.)
2.    Choose Edit User Dictionary from the Edit Menu. The Edit User Dictionary
dialog box appears.












3.    To add a word, enter it in the textbox at the bottom and click on Add.
4.    To delete a word, select it from the list and click on Delete.
To add words to the user dictionary during proofing:
*    Choose Add in the proofing dialog bar as described in the previous topic.

To save/load/unload a user dictionary:
*    Choose the appropriate menu item from the context menu or from the User
Dictionary submenu in the File menu.
*    User dictionaries can also be loaded and unloaded by clicking on the
button with three dots ('...') on the Accuracy tab in the Options dialog box.
Training
Training is the process of associating character shapes (images) with the
characters they represent. It can be done after recognition on Omnifont or Dot
matrix characters.
Most characters need not be trained. As a rule, you should train character
shapes which are repeatedly misrecognized or unrecognized. In other words: do
not train individual errors caused by accidental spots on the image. You can
also train uncommon characters and symbols.
Training can be saved to training files for future use and loaded whenever
needed. If no training file is loaded, all new training information will be
stored in memory until saved. Loaded and new training will be used by
recognition. You can unload training if it is not needed any more in the current
document. Reviewing and editing of training files is also possible. The name and
status of the currently loaded training file is displayed in the status bar.
When a character shape is trained, the program does the following:
*    Corrects the occurrence of the character used for training.
*    Looks further down on the same page and checks if the shape of any
recognized character is similar to that of the trained one.
*    Presents proposed changes to the user for confirmation.
*    Corrects all occurrences of the similar characters if confirmed.
Hints for training:
*    Always start training at the beginning of the document.
*    Use only a few pages to train characters. Training increases recognition
accuracy on subsequently added and recognized ones.
*    Use separate training files for different types of documents.
*    Even if you don't want to save your training, it can be useful to speed up
proofing.
Right-clicking on the Training file field in the Status bar displays a context
menu with training file related commands.

To train characters:
1.    To initiate training you have the following choices:
*    Click on Train in the proofing dialog bar, if you want to train the found
item or
*    Right-click on the character or selected word in the editor and choose
Train from the context menu. The Training dialog box appears:












2.    Enter the correct character in the textbox and click on Train.
3.    If characters with similar shapes are found on the same page, the Check
Training dialog appears.


















4.    Check if all proposed changes are correct. Some might be incorrect due to
the similar shapes of different letters. (For example: 'b' and 'h', 'q' and 'g',
etc.) You have the following choices:
*    If all words are correct, click on OK. The proposed changes will be made;
the changed characters will appear blue.
*    If only a few proposals are incorrect, select an incorrect word and click
on Re-train. The Training dialog box appears where you can re-train that single
occurrence. Repeat the step as required, click on OK when finished.
*    If many proposals are incorrect, you should choose neither OK nor Re-train
but Cancel. That training will be abandoned.

To save/load/unload training:
*    Choose the appropriate menu item from the context menu or from the
Training submenu in the File menu.
*    Training files can also be loaded and unloaded by clicking on the button
with three dots ('...') on the Accuracy tab in the Options dialog box.
To review/edit training:
1.    Load the training file. (You can also edit unsaved training.)
2.    Choose Edit Training File from the Edit Menu. The Edit Training File
dialog box appears.
3.    The trained shapes and associated characters will be displayed. You can
enter new characters for a shape and delete unwanted ones.



Navigating in Recognita Documents
Recognita Plus displays one page of a Recognita Document at a time; it is called
the current page. You can use the Page Browser to change pages sequentially or
randomly. Other tools help you to find pages of the document. Concise
information on pages can also be displayed for easy navigation. You can easily
copy or move pages within a document or between documents.
This section describes how to work with multi-page documents. The following
topics are included:
*    Changing Pages
*    Using the Browser
*    Finding Pages and Text
Changing Pages
To change pages you can use the buttons at the bottom left of each document
window. To use the keyboard see the online help.





The textbox in the middle shows the page number of the current page. Enter a new
page number in it and press Enter to go to the desired page. Press Esc instead
if you change your mind.
Using the Browser
The Browser occupies the left or bottom pane in the Recognita Document window.
It consists of two parts. The left part displays thumbnail size images of the
pages. The right part contains the Browser List with lines, each representing
one page.
You can use the Browser for many different things. In addition to displaying
information on pages, you can use its context menu to initiate commands. Most of
these commands apply to selected page(s), for instance (re-)recognizing, opening
and deleting pages, saving text and images, finding text, etc.


















This topic describes the following features of the Browser:
*    Moving and copying pages: useful if the order of pages is wrong.
*    Move pages to a different location within the same document.
*    Move or copy pages to another document.
*    Quick display of the recognized text: you can use it to quickly see the
results of recognition, without changing pages.
*    Adding notes to pages: later you can find pages containing given keywords
in their notes column.
To move/copy pages:
1.    Select the pages to be copied/moved from the Browser List. Standard
selection methods can be applied.
2.    Click on a selected item and hold down the mouse button. Drag the pages to
move them to the target location in the same or in another document. To copy
pages to another document, hold down the Ctrl key when releasing the mouse. The
target location is continuously indicated by an icon as shown.








3.    Release the mouse at the desired location.

To quickly display the Recognized Text:
1.    Customize the Browser's columns so that the Recognized Text column is
selected.
2.    Activate the Page Browser pane by clicking on any part of it.
3.    Move the cursor onto the Recognized Text column then leave it there. The
recognized text (as much as possible) appears in a popup window just like a
ToolTip. By moving from line to line, you can easily and quickly view the text
of many pages.

To add notes to Pages:
1.    Customize the Browser's columns so that the Note column is selected.
2.    You have two choices:
*    Select the line of the desired page and click on the Note field (or press
F2) to key in note text in-place.
*    Choose Edit Note from the context menu of the Browser to display the Edit
Note dialog box.
Finding Pages and Text
You can search for pages containing a certain string in their note field, or
find strings in recognized text quickly without opening the pages. If pages are
selected in the Browser and searching is started from its context menu, only the
selected pages will searched. Otherwise all pages are searched.

To find pages with a given string in their note field:
1.    Choose Find>In Notes from the Edit menu or from the context menu of the
Browser. The Find notes ... dialog box appears.







2.    Enter a string and click on Find Next. The first page whose note field
contains the given string will be selected in the Browser. Repeat as desired to
find further occurrences.
3.    Click Select All to select and highlight all the pages containing the
string in their note (for instance ready to be drag-and-dropped to a new
location).

To find strings quickly in the recognized text:
1.    Choose Find>In Text from the Edit menu or from the context menu of the
Browser. The Find in ... pages dialog box appears.
2.    Enter a string and click on Find Next. If found, the program displays the
text containing the string, which will be highlighted.
If the text found is on the current page, the editor also highlights the
occurrence. Pages containing the searched text will be opened only if you click
on Open Page or the Open pages automatically option is set.



Using the Character Map
The Character Map is a small popup window displaying a table of characters. It
has two forms:
*    Displaying all 464 characters Recognita Plus can recognize. Usually, you
see this table. Use it to insert characters in the text pane or into certain
textboxes in dialog boxes. It is useful especially if you want to insert special
symbols or non-keyboard characters, for example for training, searching, etc.
*    Displaying the characters and code values of the selected code page. This
is available on the Character tab of the Advanced Parameters for Saving dialog
box, and is displayed only for information. The codes help you create a user-
defined code page.

To display the Character Map:
*    Click on the Character Map tool in the Editing toolbar or choose Char. Map
in dialog boxes where available.







To insert a character from the Character Map:
1.    Place the insertion point to the desired location (in the text pane or in
a textbox of a dialog box).
2.    Click on a character to insert it. Any character can be inserted,
regardless of its current status (color).
Chapter 5
Improving Recognition Accuracy
Successful recognition depends mainly on two things: the quality of your
document and the current settings of Recognita Plus. This chapter gives you some
practical advice and tells which settings are the most important to achieve the
highest accuracy possible. But don't forget: your practical experience is at
least as important as proper settings; even the best software cannot do without
it.
In this chapter you will find information on the following topics:
*    Scanner Settings
*    Languages and Language Analysis
*    Accuracy Troubleshooting
Scanner Settings
Scanner settings can be set on the Scanner tab of the Options dialog box or on
the TWAIN data source's own user interface, if the TWAIN Basic driver was chosen
at installation or setup. Brightness can also be set on the Options toolbar.
Available settings may vary for different scanner models. The most important of
them are:
*    Brightness
*    Resolution
*    Scanning Mode.
Setting Correct Brightness
A proper brightness setting results in characters whose contours are neither
broken, nor run into each other. For good quality documents the default value
(usually 50%) gives good results. You can examine the quality of the scanned
image in the image pane at the maximum zoom setting.
Sample images scanned with different brightness values:
You should of course try to reach the optimum image quality, however this is not
always possible. Recognita Plus tolerates broken lines and touching characters
up to a certain degree, so you shouldn't worry too much.
You may still get reasonable accuracy, even if the image quality is poor, by
enabling Language Analysis. See the next section in this chapter for details on
language-related settings.
Setting Proper Resolution
A proper resolution is also necessary to get good results. Though document
quality must also be considered, as a rule, you should set
*    300 dpi for letters larger than 8 points,
*    400 dpi for letters smaller than or equal to 8 points.
Do not set resolution higher than 400 dpi; it may cause more harm than good to
your results.
Check the resolution of image files. To display resolution, enable the
Resolution column in the Browser List.
Choosing Proper Scanning Mode
Recognita Plus has four basic scanning modes you may choose from:
*    Scan B/W: most often used. Scans black and white with the given brightness
setting. Choose this for documents of reasonable or good quality.
*    Scan B/W with Auto-brightness: scans in gray using either your scanner's
image optimization software or Recognita's own facility to derive an optimum
black and white image. Gray image is not retained. Choose this setting only on
poor quality documents where the contrast varies on a single page or from page
to page.
*    Scan Gray: scans in gray. This mode is used primarily to have grayscale
images embedded in a Recognita Document for display and exporting. It also
derives an optimum black and white image giving similar results to that of the
Scan B/W with Auto-brightness mode.
*    Scan Color: This is offered if your scanner supports color. It allows
color images to be displayed in the image pane and Browser. These color images
can be printed, sent or saved to image files. With color scanning, graphics
zones in text files will also be displayed in color whenever Full or Part Format
it set. They can be printed in color.  They can also be sent or saved in color,
provided Retain Graphics is set and a suitable output format selected.



Languages and Language Analysis
In this section you will have information on the following topics:
*    Recognition Languages
*    Language Analysis (using dictionaries)
*    Omnifont Recognition Methods
Recognition Languages
It is very important to define the set of characters, to be enabled for
recognition. Typically and most often you do this simply by setting the language
of your input document. This has a major impact on how its characters will be
recognized. Recognition languages can be set in the dropdown list on the Options
toolbar or on the Accuracy tab of the Options dialog box.




When you set a language, you add the characters needed for that language to the
set of characters enabled for recognition. This is called the Language Set.
Selecting more than one language for a multi-lingual document extends this set.
Punctuation characters, numbers and other common symbols are always enabled.
If more than one language is selected, the first one selected is set as the main
recognition language. Click with Ctrl on a different language to make it the
main one. Language Analysis can be enabled if the main recognition language has
a dictionary. The main recognition language is also used to find a suitable code
page for exporting text.
The predefined set of digits, called Numbers Only, is an alternative to the
Language Set if your document contains only or almost only numbers. Both
settings can be extended by enabling additional characters individually.
To see which characters are enabled for each language, see the topic "Languages
and Accented Letters" in the online help. Its Language section also gives advice
on handling multi-lingual documents, and Code Pages for text export.
How to Customize the Language List
This feature is new to Recognita Plus 5.0. On delivery, the toolbar language
list displays the seventeen languages for which Language Analysts are available.
To customize this list:

1.    Go to the Accuracy panel of the Options dialog box.
2.    Click Customize Languages... for an alphabetical listing of all 114
    supported languages.
3.    Shorten the list if desired by de-selecting some continents or categories.
4.    Select languages in either list and use the Add and Remove buttons to keep
just the languages you need in the toolbar list. Added languages appear at the
bottom of the list.
5.    To reorder the list, select one language at a time and use the up or down
arrow buttons.
Language Analysis (using Dictionaries)
Language Analysis includes the process of using dictionaries during recognition.
If it is enabled, the Omnifont OCR engine consults the dictionary of the main
recognition language and also the current user dictionary - if one is loaded -
during recognition to verify and correct words being recognized, thus increasing
accuracy. It is also used to mark any non-dictionary words in the text
recognized by the Omnifont or Dot matrix engines.

See the next topic "Omnifont Recognition Methods" on using Language Analysis.
Omnifont Recognition Methods
The Omnifont recognition engine has six accuracy/speed levels, often called
recognition or OCR methods. These levels define how many recognition passes are
applied on each page and whether Language Analysis is used or not.





















The six recognition methods:
Recognition methods can be set on the dropdown tool in the Options toolbar or on
the Accuracy tab of the Options dialog box.




*    Level 1: One-step reading without Language Analysis. This is the fastest.
Use it:
*    For very good quality documents.
*    When speed is more important than accuracy.
*    Level 2: One-step reading, with Language Analysis. Use it:
*    For good quality documents containing typical language.
*    For pages containing very little text.
*    When speed is rather more important than accuracy.
*    Level 3: Two-step reading without Language Analysis. Called Balanced. Use
it for:
*    Typical documents of reasonable quality.
*    Reading languages for which Language Analysis is
    not available.
*    Documents with many proper nouns or non-dictionary words.
*    Pages with two or more languages.
*    Level 4: Two-step reading with Language Analysis. Use it for:
*    Typical documents of reasonable quality.
*    Documents without too many proper nouns and non-dictionary words.
*    Level 5: Three-step reading with Language Analysis. Most accurate with
single-engine recognition. Use it for:
*    Degraded documents.
*    Languages with Language Analysis but not supported by the second engine:
Catalan, Czech, Greek, Hungarian, Polish and Russian.
*    Level 6: Most accurate three-step reading with Language Analysis and dual-
engine recognition. Use it:
*    When maximum accuracy is vital and slower processing does not matter.
*    On powerful fast computers.
*    For the languages supported by both engines: Danish, Dutch, English,
Finnish, French, German, Italian, Norwegian, Portuguese, Spanish or Swedish.
Accuracy Troubleshooting
Many things can cause unexpectedly poor or incorrect recognition results. This
section summarizes typical problems and their reasons. A new setting and re-
recognizing can solve most of the problems.

Poor recognition:
*    Low image quality due to poor brightness or resolution setting.

Many green highlights, though words are mainly correct:
*    Wrong language was set with Language Analysis enabled.
*    Wrong or missing user dictionary.

Many wrong characters, earlier recognized correctly:
*    Wrong or missing Training file.
*    Characters earlier enabled individually are no longer set.

Missing accents or misrecognized accented characters:
*    Wrong language was set.

Many nonsense words and garbage characters:
*    Wrong recognition engine was set, (for example, Dot matrix recognition
engine was used instead of Omnifont or vice versa)
or automatic recognition type detection did not work correctly.
*    Image orientation is wrong. Either you placed the document in the scanner
the wrong way or the automatic orientation detection was incorrect. You can
rotate and (re-)recognize the images.

Garbage characters in certain lines:
*    Improperly placed zones cutting a line in two parts.
*    Improperly placed gridlines in a table zone.
*    Improper margin setting in Tools/Options/Area.

Text contains mainly numbers and reject symbols:
*    Omnifont, Braille or Dot matrix recognition was run on zones containing
normal text but with the Numbers Only property set, or the Handprinted numbers
recognition engine was used on normal printed text.
