Selecting your scanner
Before you can select a scanner in OmniPage Pro X, its driver must already be installed on your system. It should also be tested, to be sure it is working properly with the scanning software supplied by its manufacturer. Consult the documentation supplied with your scanner.
You can either let OmniPage Pro auto-detect your scanner or you can select a scanner type manually in the Select Scanner dialog box. If you cannot find your scanner model in the scanner list in this dialog box,
OmniPage Pro allows you to select a driver from one of the two
Tip
general scanner driver types supported by the program. You can select either a Photoshop plug-in or a TWAIN driver depending on your scanner.
For specific scanner types which work with a TWAIN driver, you can choose whether to use their own interface or use OmniPage Pro’s interface. For scanners using a Photoshop plug-in driver, its interface is always displayed while scanning.
Each scanner driver provides a different user interface, so the available options may vary.

Chapter 2
Introduction
You probably do business correspondence and other written projects on your computer. However, certain sources of information may not be immediately available for use. For example, if you want to incorporate part of a magazine article into a document in your word processor, you somehow have to get its text into your computer.
Painstakingly retyping the article is not an appealing solution.
OmniPage Pro X offers a smart solution to increase your productivity.
Its optical character recognition (OCR) technology accurately and easily converts text from scanned pages and image files into editable form for use in your favorite computer applications. You do not have to retype whole texts — OmniPage Pro does it for you.
Please continue reading this chapter for information on these topics: u u u u

OmniPage Pro X User’s Guide 19
20 Introduction
What is Optical Character Recognition?
Optical character recognition (OCR) is the process of extracting text from images. Images can result from scanning paper documents or opening image files. Images do not have editable text characters; they have many tiny dots (pixels) that together form character shapes.
These present a picture of the text on a page.
During OCR, OmniPage Pro analyzes the character shapes in an image and determines character solutions to produce editable text. In other words, the OCR program ‘reads’ the page.
After OCR, you can export the recognized text to a variety of wordprocessing, desktop publishing, and spreadsheet applications.
Beyond OCR
In addition to text, OmniPage Pro X can retain the following elements in a document after OCR for display and export.
t Graphics
Photos, logos and drawings are examples of graphics. The program cannot recognize handwriting, but signatures can be saved as graphics.
t Text formatting
Font types, sizes, and styles (such as bold or italic) are examples of character formatting. Indents, tabs, margins and line spacing are examples of paragraph formatting.
t Page formatting
Column structure, paragraph spacing, and placement of graphics are examples of page formatting.
The elements that are retained depend on settings you select before
OCR and on the capabilities of the saving format you choose. See chapter 4, Settings, for more information.
Chapter 2
Basic steps in the OCR process
There are three main steps in OmniPage Pro’s OCR process. They correspond to three large numbered buttons in the OCR Toolbar.
Documents can be processed automatically or manually. In automatic processing, the Start button takes all specified document pages through the whole process (1-2-3) without a stop. Processing is done according to settings selected in pop-up menus on the OCR Toolbar and in the Preferences dialog box. In manual processing, each step can be performed separately and settings can be modified between each step. The three basic steps are:
1.
Acquire page images
Scan pages or load one or more image files. See page 36. A
miniature image of each page appears in Thumbnail view, the image of one page appears in Image view.
A layout description assists auto-zoning and a style set defines a formatting level for the recognized pages. When processing manually, zones should be drawn and styled at this point.
2.
Perform OCR
Pages can be recognized with or without proofing. See page 51.
During recognition, zones are automatically created on all pages without existing zones. On pages with zones, auto-zoning can be requested. OmniPage Pro performs OCR on text zones and can transfer graphics zones. Recognition results appear in Text view.
3.
Export the document
The document can be saved to a specified file name and format, or copied to Clipboard. The document remains open in OmniPage
Pro after its first export, allowing text to be further edited and pages added or re-recognized with changed settings and zoning.
The document can be saved repeatedly, also to different saving formats.
It can be saved as an OmniPage Document, allowing it to be
reopened later in OmniPage Pro X. See page 38, 56 and page 61.
See the topics Automatic processing and Manual processing at the
beginning of chapter 3.
Basic steps in the OCR process 21
The OCR Toolbar
Start button: Use this to start and re-start automatic processing, and to stop any processing.
Assistant button:
Guides you to select settings and launches automatic processing.
The status line reports the current operation or the operation you can do next.

The Start button lets you activate or re-activate automatic processing. When processing is in progress, it displays Stop.
The Get Page, OCR and Export buttons are for manual processing.
They allow each step to be performed separately, as follows:
• The Get Page button lets you acquire one or more images from file or by scanning with the specified mode.
• The OCR button lets you send the current page to recognition, or re-recognition, with or without proofing automatically started. It also allows training to be done.
• The Export button lets you save results from all recognized pages in the document to file or copy them to Clipboard.
The five pop-up menus let you select options. Processing is done according to the selected options. Before starting automatic processing, you must ensure all these options are suitable.
The current primary recognition language is displayed. Three dots after the language name denote that at least one secondary language is also selected.

To restore Image view, drag it to the right.
The Document window can be minimized and restored. Closing the document window closes the current document (with a warning if unsaved changes exist).
The Thumbnail window
The Thumbnail window appears vertically on the left of the desktop to provide Thumbnail view. This displays numbered miniature pictures (thumbnails) of all pages in the current document. You can use thumbnails to move to other pages, reorder or delete pages. An icon at the bottom right of a page indicates that the page has been recognized.
You can import one or more images to a defined location inside a document by drag-and-drop. You can also use a thumbnail to drag a copy of a page image from a document to the Desktop, a file location or into other applications.
The Thumbnail window has a scroll bar and can be dragged to other locations. The window cannot be closed, under Mac OS 9 it can be minimized.
Use the Tools palette to draw regular or irregular zones, modify zones, apply a zone template, reorder zones, erase parts of the image, zoom in or out on the image, handle table zones, or rotate an image.

28 Processing documents
For example, OmniPage Pro can scan a stack of pages from a scanner’s automatic document feeder (ADF), create zones on all pages, recognize the pages, offer the results for proofing, and then let you save the recognition results to file.
During automatic processing, auto-zoning always runs, unless you specify a zone template file. If you want to draw or modify zones manually, you can do this after recognition and first export are finished, and then re-recognize those pages afterwards.
To prepare for automatic processing
1. Select the source for one or more page images .
Choose Load image to open one or more page images from file.
Choose Scan in B&W to scan in black-and-white.
Choose Scan in Gray to scan in grayscale.
Choose Scan in Color to scan in color (with a color scanner).
See Bringing page images into OmniPage Pro on page 36 and Get
Page options on page 70 for information on these choices.
2. Select a style set.
Choose a style set to define the formatting level and page layout you want applied to the recognition results.
See page 72 and page 73 for information on these choices.
3. Select a page layout description.
Choose a page layout description to influence the auto-zoning.
Choose from Single Column, Multiple Column, Spreadsheet or
Mixed Pages. Or choose a zone template if you have one.
4. Select the type of recognition you want.
Choose Perform OCR to have recognition without proofing. You
can still proof the text later, after its first export. See from page 50.
Choose OCR & Proof to have proofing started as soon as all pages
5. Select an export target for the document.
You can direct your document to be saved to a file whose name, location and type you define, or have the recognition results
copied to the Clipboard. See page 64.
6. Ensure all other settings are in order.
Further settings are located in the Preferences dialog box (see chapter 4). These include recognition languages, user dictionaries and scanner settings. If you are scanning, place your page(s) correctly in the scanner. To scan multiple pages from an ADF, select Scan Until Empty in the Scanner Panel of the Preferences dialog box.

6. If proofing was requested, it starts from the top of the first page.
Make corrections as desired. Click in Text view to interrupt proofing. Then you can edit or verify the recognized text, move to other pages or change settings. The proofreading button Ignore becomes Start. Click this to resume proofreading. Click Done to finish proofing before the end of the document.
7. The Export dialog box appears if you chose export to file. Define a folder, file name and saving format, and choose other export options. If you chose Save and Launch, the recognition results will appear in the target application. If you chose export to Clipboard, a message tells you when the recognition results have been placed.
The document remains open in OmniPage Pro for further editing.
Pages can be re-recognized with changed zoning or settings. New pages can be added. The document can be saved repeatedly.
During processing, the Start button becomes a Stop button. Click it to stop processing. The current processing step is discarded but the results of all completed steps remain. For example, if you click Stop during OCR, there will be no recognized text but the image remains.
To process an existing document automatically
You can also click Start to perform automatic processing when you have a document open. It does not matter whether its pages were processed automatically or manually. To scan new pages into the document, place them in the scanner correctly. When you click Start, the OCR Instructions dialog box offers you the following choices.
u Load and Process Additional Pages
If the selected source is from file, the Load Images dialog box appears, allowing you to specify files. Otherwise, scanning will start immediately. If Scan Until Empty is selected, all pages in the
ADF will be scanned one after the other. All specified pages enter the document and are recognized. Existing pages remain unchanged, even if some of them were unrecognized. If the current page was the last in the document when you clicked Start, the new pages are appended to the end of the document. If not, the Acquire Images dialog box lets you specify where to place the new pages. When recognition (and optionally proofing) are completed, the whole document is exported: sent to Clipboard or saved to file through the Export dialog box.
u Process All Unrecognized Pages
Recognition (and optionally proofing) is performed on all unrecognized pages. No new pages can be added if this option is selected. When processing is finished, or if there are no unrecognized pages, export starts, to Clipboard or file as specified.
When saving to file, the Export dialog box appears. All changes to all pages are saved, not just the pages recognized by this command.
u Reprocess All Pages
All recognition results for all recognized pages in the document will be discarded, and all images will be (re-)recognized. Any image without zones is auto-zoned. If any zones exist, the Zoning
Instructions dialog box lets you choose to use current zones only, to discard all zones and have auto-zoning, or to run auto-zoning in addition to existing zones. Your choice will be applied to all pages containing manually drawn or modified zones.
Automatic processing 31
32 Processing documents
Manual processing
You can use manual processing when you want greater control over the OCR process. Processing proceeds step-by-step. This allows you to view and manually zone images before you send them for recognition.
It also lets you modify settings between each processing step or from page to page. That can be important if some pages in the document need different settings from others.
During manual processing you can acquire multiple pages with each click of the Get Page button. Similarly, the Export button is for exporting recognition results from all recognized pages in the document. By contrast, the OCR button is used to have only the current page processed.
Steps for manual processing
Three OCR Toolbar buttons let you control the process step-by-step:
1. Acquire images
Define the image source in the Get Page pop-up menu. Choose to scan pages or to load one or more image files. Click the Get Page button (number 1). A miniature image of each page appears in
Thumbnail view, the image of one page appears in Image view.
Recognition does not start. See Bringing page images into
OmniPage Pro on page 36 and Get Page options on page 70.
2. Create zones on the images
Draw zones in Image view using the Tools palette. Zones are areas that define which parts of a page image should be recognized. You can also load template zones and draw zones in addition to the zones placed from the template. See Creating and modifying zones
on page 39 and Zone templates on page 96.
3. Perform OCR
Specify to have recognition, with or without proofing, or to do training in the OCR pop-up menu. Click the OCR button
(number 2). Choose to use existing zones only or to allow autozoning on all unzoned parts of the page. Any page without zones
will be auto-zoned. You will see a progress indicator as the current page is recognized. After OCR, recognition results appear in Text view. If you requested proofing and there are suspect words on the page, proofing begins immediately. If you did not request proofing, you can view, edit and verify the recognized text or start proofing from any point in the text.
See Performing OCR on page 50 and Training OCR on page 97.
4. Export the document
Specify an export target in the Export pop-up menu. You can save recognition results to one or more files, or have them copied to the
Clipboard. Click the Export button (number 3). If you are saving to file, specify the file name, format and location.
See Exporting documents on page 61 for more information.
Using automatic and manual processing together
Automatic processing provides speed and efficiency. After you have selected settings, many pages can be processed from start to finish without user intervention. Manual processing demands more attention, but gives the user greater control over the recognition results. It is possible to tap into both benefits while processing a single document. Suppose you have a long document, ideally suited to automatic processing, except for a few pages needing separate zoning or settings. We provide two examples of how you could proceed.
t To start automatically and finish manually:
1. Prepare settings and then process all pages automatically.
2. Export the document to protect it, maybe as an OmniPage
Document.
3. Examine the recognition results, especially on pages you think will need individual attention. Identify which changes are needed to zoning or settings.
4. Make the required changes on a page and reprocess it manually by clicking on the OCR button.
Using automatic and manual processing together 33
5. Specify a choice in the Zoning Instructions dialog box.
6. Repeat steps 4 and 5 until all pages are adequately recognized.
7. Export the finished document as required.
t To start manually and finish automatically:
1. Prepare settings and acquire all the images for the document by clicking the Get Page button.
2. Examine the images for suitable brightness, orientation and content. Rescan or rotate unsuitable images. Use the eraser tool or zoning to remove or exclude spotty and degraded areas. Reorder pages as desired.
3. Manually zone pages needing special attention. Place pictures or diagrams in Graphics zones and areas you do not want recognized in Ignore zones. Draw and specify text zones.
4. Click the Start button and choose Process All Unrecognized Pages in the OCR Instructions dialog box.
5. Make a choice in the Zoning Instructions dialog box for all pages.
Choose Use Only Current Zones or Keep Current Zones and Find
Additional Zones.
6. After proofing (if requested), you can export the document.

4. Click the Get Page button in the OCR Toolbar.
Pages are scanned in order and the resulting images appear in
Thumbnail view. The first page is displayed in Image view.
Loading image files
You can load JPEG, PDF, PICT and TIFF image files into OmniPage
Pro. An image file is an electronic picture of text, such as a fax or scanned image, that is saved in an image file format. You can load more than one file at once. You can also load selected or all pages from multi-page image files (these can be in TIFF or PDF formats).
36 Processing documents
t To load a single page image file:
1. Select Load Image as the option in the Get Page Pop-up menu.
2. Click the Get Page button. The Load Images dialog box appears. It is a standard Macintosh dialog box.
3. Specify in the Show pop-up menu which files should be listed: All image files, or only files with a single format.
4. Select the folder containing your file with the From pop-up menu.
5. Select the file you want to load and then click Open. Or, doubleclick the file name.
The image from the file is displayed in miniature in Thumbnail view and at the specified magnification in Image view.
t To load multiple images from file:
1. Select Load Image in the Get Page pop-up menu and click the Get
Page button. Select which file types should be listed.
2. Under the OS X operating system, select files as follows:
• Files listed together: Shift+click the first and the last file names. These files and all in between will be selected.
• Non-adjacent files: Command+click each file.
Command+click a selected file to deselect it.
3. Click Open after you have selected all the files you want to load.
Image files are loaded in the order they are listed and combined into one working document.
4. When opening a multi-page image file (TIFF or PDF), you can select which pages to open. Miniature page images appear in
Thumbnail view and the first page is displayed in Image view.
5. Drag page images to new locations in Thumbnail view if the pages do not appear in the desired order.
Note If you scan or load pages while a document is currently open with its last page displayed, new pages are appended to the end of the document. If the last page is not the active one, you will be asked where to place incoming pages.
Bringing page images into OmniPage Pro 37
Opening OmniPage Documents
You can open an OmniPage Document using the Open command in the File menu. An OmniPage Document (OPD) is a file in OmniPage
Pro’s proprietary format. OPDs contain original page images, zones, settings and recognition results (if any). Each piece of recognized text remains linked to the image it came from, so text can still be proofed and verified when the OPD is reopened. You can also make editing changes to recognized text, re-recognize pages and add further pages to the document. You can save recognition results from the OPD more than once, for instance to different file formats.
Note OmniPage Pro can only have one working document open at a time. If you try to open another file while you have a document open, you are prompted to close the current document. However, you can add pages to your current document using the Get Page button.
t To open an OmniPage Document:
1. Choose Open... in the File menu.
The Open OmniPage Document dialog box appears.
2. Open the folder where your OmniPage Document is located.
3. Double-click a file name or select the file and click Open.
The OmniPage Document opens with one thumbnail image for each page. The original image of the first page appears in Image view and its recognition results (if any) in Text view. Some settings from the OPD are activated.
Note
For advice on saving OmniPage Documents, see page 56 and page 62.
Using drag-and-drop
You can import images into an open document by drag-and-drop from the Desktop or Finder. Use Shift-clicks to select multiple files.
You can import multi-page image files; the Select Pages dialog box allows you to specify which of the file’s pages to open.
38 Processing documents
If you drag and then drop the image icon on Image view, the page or pages are appended to the end of the document.
If you drop the image icon on Thumbnail view, you can choose where to have the page(s) placed. As you drag the icon over the pages, a black bar appears between two pages. Drop the icon to have the new page(s) placed immediately below the bar.
The first of the imported pages becomes the current page.
You can launch OmniPage Pro X and load one or more images to start a new document. Drag an image file icon from the Desktop or Finder onto the OmniPage Pro X icon.
If you drag an image file icon onto the OmniPage Pro icon when you have the program running with a document, the new image is appended to the document if its last page was active, otherwise a dialog box lets you specify where to place the new image(s).
You can also launch the program by dragging the icon of an
OmniPage Document onto the program icon, or by double-clicking the OPD icon. You cannot drag an OPD file into an open document.
In this case, you will be invited to save any changes to the current document before it is closed and the OPD opened.
Note
To use drag-and-drop to export recognition results, see page 65.
Creating and modifying zones
Page images are displayed in Image view. This is where zones can be manually created before OCR. Zones are bordered areas that identify parts of a page that will be recognized as text, retained as graphics or ignored. Any part of a page not enclosed by a zone is ignored during
OCR, unless you specify that auto-zoning should run.
Note You can create zone templates to use when you process documents with the same zoning requirements. Zone templates remember the shape, position, order, type,
contents, and style of zones. See Zone templates on page 96.
Creating and modifying zones 39
40 u u u
This section presents the following topics: u
Creating zones automatically
OmniPage Pro can create zones automatically for you. To do so, it uses the selected page layout description to find blocks of text and graphics on the page, place these in zones and decide a reading order. t To run auto-zoning during automatic processing:
1. Choose a setting in the Original Layout pop-up menu that most closely matches the layout of your page or pages.
Select Single Column, Multiple Column, Spreadsheet, Mixed
Pages, or a template of your own. See Original Layout options on
page 72 for more information on these settings.
2. Check all other settings, then click the Start button to begin automatic processing. This will include auto-zoning (unless you applied a template and chose Use Only Current Zones).
After recognition, the automatically detected zones are displayed in Image view. Each zone has a number indicating the order in which it was recognized. The zone icon next to the number indicates the zone type. If the zone locations, types or order are not suitable, change the zoning and then re-recognize the page.
t To run auto-zoning during manual processing:
1. Choose a setting in the Original Layout pop-up menu that most closely matches the layout of your page or pages.
2. Click the OCR button to have the current page zoned and recognized. If there are no zones on the page, OmniPage Pro will automatically create zones and display them after recognition. If the page has at least one zone, the Zoning Instructions dialog box offers the following choices:
Processing documents
• Use Only Current Zones (auto-zoning will not run)
• Discard Current Zones and Find New Zones
• Keep Current Zones and Find Additional Zones.
Specifying zone types
All zones are identified as a particular type. This determines the way they are treated during OCR. You can specify zone types using the tools at the top of the Zone Info palette. This palette always appears when Image view is active.
Single Column Text zone
Automatic zone
Table zone
Multiple Column Text zone
Ignore zone
Zone type and contents currently selected.
Reverse Text zone
Graphic zone
The Zone Type display box tells you the zone type of the currently or last selected zone. The corresponding zone type tool has a ‘pushed-in’ appearance. When multiple zones with different types are selected, the display box will show ‘Mixed Zone Types’.
Click a tool to change the zone type. This will apply to all currently selected zones (if any) and to new zones drawn from now on. Here are the properties of the different zone types: t Automatic zone type
This zone type gives OmniPage Pro the right to make its own decisions on how to handle the contents of the zone. It decides whether the zone contains text or graphics. It decides whether text is in columns or not and reversed or not. Any side-by-side columns detected are treated as flowing text (moving top to bottom, then left to right). Automatic zones have purple borders. After recognition, the automatic zone may be replaced by a set of smaller zones.
Creating and modifying zones 41
t Single Column Text zone type
OmniPage Pro treats all contents as one block of text; it does not look for columns or detect graphics. Tabs are inserted between any side-byside columns detected within a zone, so this zone type can be used for tables or texts in columns you do not want decolumnized or placed in a table grid. These zones have blue borders (denoting a zone containing text).
t Multiple Column Text zone type
OmniPage Pro tries to find columns within the zone area. If it finds them, the text is decolumnized (unless True Page is selected as the style set). After recognition, each column is likely to have its own zone.
Graphics will not be detected inside the zone area. These zones also have blue borders.
t Table zone type
OmniPage Pro will treat the zone contents as a table. The contents will be placed in a table grid or in tab-separated columns, as requested in the Miscellaneous panel of the Preferences dialog box. These zones have orange borders and dividers. They must be rectangular (not irregular).
t Graphic zone type
OmniPage Pro treats all contents as a graphic area; it will not extract text from the zone. If Retain Graphics is selected, it copies the image area and transfers it to Text view. If True Page is selected as the style set, the graphics areas appear in frames in their original locations. In all other cases, the graphics are placed at the end of the recognized text from the page. These zones display a graphic icon and have black or white borders, depending on the background color.
t Reverse Text zone type
If the page contains reverse text (white or pale letters on a black or dark background), place this in a separate reverse text zone. The text will be recognized and displayed as normal text. If you want the text
42 Processing documents
reversed in your output document, do this in your target application.
These zones have black or white borders, depending on the background color.
t Ignore zone type
OmniPage Pro ignores the zone entirely during auto-zoning. This is useful if you want OmniPage Pro to draw zones automatically but first want to identify areas to be ignored. By excluding complex tables or areas of line-art you do not need, you can speed up processing considerably. These zones have red borders and stripes.
Tip
You can change the zone type of individual zones any time before OCR. For example, suppose auto-zoning placed a Single Column Text zone over two columns of text. If you do not want tabs inserted between the two columns, you can change the zone type to Automatic or Multiple Column Text. The columns will then be recognized separately and text will flow from one column to the next.
t To specify a zone type:
1. Click the Draw/Select Zones tool in the Tool palette if it is not already selected.
If the Tools palette is not visible, check that Image view is active and (in Mac OS 9) that the palette has not been minimized.
2. Select the zone you want to identify by clicking it.
• Shift-click to select additional zones.
• Double-click the Draw/Select Zones tool or choose Select All in the Edit menu to select all zones on the current page.
3. Click the desired zone type in the Zone Info palette.
The zone type of all selected zones will change accordingly. This value will also be used for new zones that you draw.
t To specify zone contents:
1. Select a zone whose zone contents you want to modify.
Zone contents can be specified only for text zones, that is for
Automatic, Single Column Text, Multiple Column Text, Table or
Reverse type zones.

44 Processing documents
You can draw up to 64 separate zones. Draw zones in the order you want them processed. A number at the top left of each zone indicates the reading order.
If you draw a zone over an existing one, the borders of the new zone will wrap around the existing zone. The zones will not overlap. t To draw an irregular zone:
1. Click the Polygon tool in the Tools palette. The mouse pointer becomes a drawing tool in Image view.
2. Make sure no existing zones are selected.
3. Click the appropriate zone type in the Zone Info palette.
4. Position the drawing tool where you want to start drawing the first side of the zone and click the mouse button once.
5. Move the drawing tool to form the first side of your zone.
6. Click the mouse button again when the dotted line has the desired line length. The line becomes solid.
7. Draw a perpendicular line in either direction and then click to form the next side of the zone.
8. Repeat step 7 to finish drawing each side of your zone.
9. Double-click to close the shape.
You will not be allowed to draw a line if it constitutes a restricted shape. The following zone shapes are restricted:
Indented along the bottom
Indented along the top
Hole in the middle
If you draw an irregular zone when the zone type is set to Table, it will change to Single Column Text. You cannot change the zone type of an irregular zone to Table.
Creating and modifying zones 45
Modifying zones
Zones can be modified before OCR takes place. You can move, copy, resize, reorder, extend, connect, divide, and delete zones. If you modify zones after recognition, you will have to re-recognize the page for the modifications to take effect.
The Modify Zones tool is for adding and subtracting zone areas.
Typically, this results in irregular zones, so it is not available for table type zones. This tool is also for connecting and dividing zones.
t To move zones:
1. Click the Draw/Select Zones tool in the Tools palette if it is not already selected.
2. Place the mouse pointer inside a zone.
3. Hold down the mouse button and drag the zone where you want to move it. Or use the arrow keys. Only the zone borders are moved. The contents of the page image remain as is.
t To resize zones:
1. Click the Draw/Select Zones tool if it is not already selected.
2. Select the zone you want to resize by clicking it.
Handles appear on the zone border.
3. Select a handle, hold the mouse button down, and drag the mouse pointer in the direction you want to enlarge or reduce the zone.
4. Release the mouse button when you are done.
The zone border changes to display the modified zone area.
t To reorder zones:
1. Click the Order Zones tool. The numbers in the zones disappear.
2. Click within the zone you want to have recognized first.
The number 1 appears in the zone.
3. Click within the next zone you want recognized.
The number 2 appears in the zone.

Performing recognition
Performing recognition involves analyzing character shapes found in an image and generating editable text from them. This is also referred to as performing OCR. After OCR, you can proofread for recognition errors and misspelled words before you export the text to another application. u u u u u
This section describes the following procedures:
Performing OCR
Before performing OCR, make sure the current zones and settings are appropriate for your document. For example, to transfer the contents of graphic zones to have them embedded in the recognition results, you must select Retain Graphics in the OCR panel of the Preferences
dialog box. See OCR settings on page 80.
t To perform OCR on a single current page:
1. Select Perform OCR or OCR & Proof in the OCR button’s pop-up menu. OCR & Proof prompts you to check for errors after OCR.
2. Click the OCR button.
The page is recognized according to the current zones and settings.
If there are no zones on the page, zones are created automatically or with a currently selected zone template. Recognition results appear in Text view.
To recognize more than one page at a time, you must use
automatic processing (see page 31).
50 Processing documents
Proofreading OCR results
Recognized text appears in Text view after OCR so you can check for errors and misspellings in the text before exporting it.
Error checking (proofing) starts automatically after OCR if you chose
OCR & Proof as the OCR option. It starts from the first recognized page and continues through all recognized pages in the document. If you chose Perform OCR you must start proofing by choosing Proofread
OCR... in the Edit menu as described below. Then, proofing starts from the current cursor position.
You can select main and secondary recognition languages, a user dictionary and whether to use a Language Analyst or not in the
Spelling panel of the Preferences dialog box. See Spelling settings on
page 82 for more information. See also User dictionaries on page 101.
t To check and correct errors in recognized text:
1. Choose Proofread OCR... in the Edit menu.
Proofing stops on words containing an unrecognizable character and displays them red. An unrecognizable character is replaced by a red reject character; a tilde ( ~) by default.
If a Language Analyst is enabled, proofing will also stop on:
• Words containing one or more characters recognized with a lower degree of certainty (words displayed green )
• Words flagged by the Language Analyst, for instance for not being found in a main or user dictionary (displayed in blue )
You can choose whether or not to stop on acronyms, abbreviations and proper names in the Spelling panel of the Preferences dialog box.
When OmniPage Pro stops on a word, it highlights the word in
Text view. These words will also have color markers if Show
Markers is enabled in the Edit menu. The Proofread OCR dialog box shows the original image of the word (also highlighted) in its context on the original page.

Saving to Portable Document Format (PDF)
When saving to PDF, we recommend you choose the True Page style set, because this forms the basis for saving, whatever style set is chosen.
Check that all text is visible within the frame borders. You have four choices when saving recognition results to PDF files.
Image only: The PDF file is viewable only and cannot be modified in a PDF editor and text cannot be searched.
Normal: The PDF file can be viewed and searched in a PDF viewer and edited in a PDF editor.
With Image on text: The PDF file is viewable only and cannot be modified in a PDF editor. There is a text file behind each image, so text can be searched. A found word is highlighted in the image.
With image substitutes: Words with reject and suspect characters have image overlays, so uncertain characters display as they were in the original document. The PDF file can be viewed, edited and searched.
Copying a document to the Clipboard
You can choose to send a copy of the recognition results from all recognized pages in the document to Clipboard. This can then be pasted into another application. You can also copy the image block from a zone in Image view to the Clipboard.
t To copy an entire document to Clipboard:
1. Select To Clipboard in the Export button’s pop-up menu.
2. Click the Start button for automatic processing or the Export button to export pages manually.
The results from every recognized page are copied to the
Clipboard. With manual processing this happens immediately.
With automatic processing it happens when the last page is recognized or proofed.
3. Paste the Clipboard contents to a target application.
Text formatting, such as bold and italics, is retained if you paste it into an application that supports RTF information. Otherwise,
Processing documents
only plain text is pasted. Graphics are retained if you selected
Retain Graphics and the target application supports them. The graphics have the resolution chosen in the OCR panel of the
Preferences dialog box.
t To copy the image from a zone to Clipboard:
1. Make Image view active.
2. Click the Draw/Select Zones tool in the Tool palette.
3. Select the zone you want to copy by clicking it.
4. Choose Copy in the Edit menu. A copy of the image from the zone area is placed on the Clipboard. It can be pasted into any target application capable of handling PICT images. It retains its original resolution and color depth value (up to 256 colors).
Note Copying through Clipboard (and Direct OCR) work best for processing just a few pages, especially under Mac OS 9 if an application’s partition is almost full. Save larger documents to a file format compatible with your application.
Using drag-and-drop functionality
Drag-and-drop can be used for import (see page 38) and export.
Dragging a thumbnail for whole page export
You can drag a thumbnail from Thumbnail view to the Desktop, to a folder or to another application that supports drag-and-drop functionality. The image of the thumbnail’s page is placed as a PICT image with the same resolution and mode (black-and-white, grayscale or color) as the original image. If it is dragged to the Desktop or a folder, it is named Picture clipping, with a numerical suffix if necessary.
Dragging a zone from Image view
You can drag a single selected zone from Image view to the same locations. A copy of the zone contents is placed as a PICT image, with the same behavior as for a whole page.

Dragging from Text view
You can drag a block of selected recognized text from Text view to the
Desktop or another application that supports drag-and-drop functionality. Text formatting will be transferred if possible. The result appears on the Desktop as a picture clipping icon, and double-clicking on it allows you to view the text only. But if you drag the icon into a text editing application, it is inserted as editable text. An embedded graphic can be exported by drag-and-drop from Text view. However, you cannot drag-and-drop text and graphics together.
Direct OCR
The Direct OCR™ feature allows you to activate OmniPage Pro from the Dock (Mac OS 9: Apple menu), perform OCR on one or more images, and have the recognized text placed at the insertion point in a target application.
Direct OCR works with virtually any Macintosh application that supports pasting text from the Clipboard. Your Macintosh must have enough memory to run both OmniPage Pro and the application.
OmniPage Pro does not have to be running when you start Direct
OCR. If it is running with no document, it will remain open afterwards. If it is running with a document open, you will be prompted to close it first. Before starting Direct OCR, be sure the
Clipboard does not contain something you still want to paste.
Text formatting, such as bold and italics, is retained if you are pasting into an application that supports RTF information. Otherwise, only plain text will be pasted. Graphics are transferred if Retain Graphics was selected and the target application supports them.
Note If the Direct OCR icon does not appear automatically in the Dock, you should drag the icon from the OmniPage Pro: OmniPage Extras folder and drop it into the Dock.
Using Direct OCR
You can run Direct OCR using automatic or manual processing. For automatic processing, all settings should be selected suitably in
OmniPage Pro before using Direct OCR. If you are uncertain whether settings are suitable or not, or if you want to exclude parts of the pages, use manual processing instead. This allows you to check and change settings and also do manual zoning.
Choose Direct OCR settings (including the choice of automatic or manual processing) in the Miscellaneous panel on the Preferences dialog box before you use Direct OCR.
Click this icon to see Direct
OCR settings.
Select this for automatic processing. The Start button is triggered as soon as you activate Direct OCR.
Deselect this to use manual processing.
Select this to keep
OmniPage Pro and the document open after Direct
OCR is finished.
t To use Direct OCR with automatic processing:
1. Align a page in your scanner or a stack of pages in its automatic document feeder (ADF) if you plan to scan. Be sure Scan Until
Empty is enabled if you want to scan multiple pages from the ADF.
2. Open or switch to the application and place the insertion point where you want recognized text to be placed. You do not need to open OmniPage Pro itself.
3. Click the OmniPage Direct OCR icon on the Dock. OmniPage Pro opens in Direct OCR mode. Either scanning starts or the Load
Images dialog box appears so you can select image files.
4. Pages are processed automatically. This includes auto-zoning, unless you apply a template and choose Use Only Current Zones.
The Export button displays To application, blocking other export

until the Direct OCR operation is finished. Proofing starts as soon as the last page is recognized, if OCR & Proof was selected.
5. When recognition or proofing is finished, the recognition results appear at the insertion point in the target application.
t To use Direct OCR with manual processing:
1. Follow points 1 to 3 as for automatic processing.
2. The OCR Toolbar appears. Scanning starts or the Load Images dialog box lets you name image files.
3. Do manual zoning on the resulting page images if you wish.
Modify settings as necessary.
4. Select an OCR method and click the OCR button for each page, or click the Start button and then choose Recognize All
Unrecognized Pages.
5. Proof each page if you asked it to start automatically. Verify and edit text as desired. Start proofing manually if you wish.
6. The Export button displays To Application. If you clicked Start, export follows automatically. If not, click the Export button.
All recognized pages are placed at the insertion point in the target application.
t What happens after Direct OCR
If you selected Keep OmniPage Pro Running after Pasting, with
Direct OCR Document Loaded in the Miscellaneous panel of the
Preferences dialog box, OmniPage Pro remains open with the images and recognition results, allowing you to verify, edit and save the document to file.
If you deselected this option, the recognition results are available only in the target application and on the Clipboard. If OmniPage
Pro was closed when you started Direct OCR, it will be closed down. If it was open when you started Direct OCR, it will remain open, without a document.

Tip
• Select Flipscape to have landscape images rotated by 180 degrees.
Flipped and Flipscape options are useful if you are scanning pages in a book and have trouble positioning the book correctly in the scanner. You can also rotate a page image after it is loaded into OmniPage Pro. For more information, see
ADF settings
If you use a scanner with an automatic document feeder (ADF), you can use the following settings.
• Select Scan until Empty to scan every page in your scanner’s
ADF.
This setting is useful when you want to scan a stack of pages at once. If it is not selected, OmniPage Pro only scans the first page in your ADF and you must click the Get Page or Start button to scan each subsequent page.
• Select Double-sided Pages to scan pages that have text printed on both sides.
OmniPage Pro scans pages and then prompts you to turn them over so it can scan the reverse sides. If you have a stack of double-sided pages, also select Scan Until Empty. After scanning, page images are displayed in Image view in the correct order. If you have a duplex scanner, do not set this; the scanner’s own software can handle the double-sided scanning.
Scanning Resolution
Use this to select a scanning resolution in dots per inch (dpi). The values offered are scanner dependent. For non-color scanning they may range from 200 to 600 dpi, and from 200 to 300 for color scanning. In general, 300 dpi is best for OCR accuracy. 400 dpi may be better for very small print. Higher resolutions may be desirable for saving higher-quality images to file or to OmniPage Documents, at the expense of increased file size, processing time and maybe OCR accuracy.
Chapter 4
Brightness
The brightness setting for scanning a page works like that on a photocopier. This setting can compensate for variations in paper and print quality, so it can have a big influence on OCR accuracy.
Click the Manual Brightness check box and move the slider to lighten or darken the brightness for your scanning.
The following illustrates optimum and unsuitable brightness.

Manual Contrast check box and move the slider to make a contrast setting.
Note Some scanners offer only automatic detection for brightness and contrast. Some require a manual setting. Others offer both methods. In this case, automatic detection may be better; some scanners do this dynamically, varying the setting for different parts of the page. If results are disappointing, try using manual adjustment.

Retain Graphics switch
Select Retain Graphics if you want OmniPage Pro to retain original graphics, such as photographs or drawings, in the recognized document. They will be displayed in Text view and exported to file, provided the selected file format supports graphics. Graphics can be exported by drag-and-drop, copying to Clipboard and Direct OCR.
Make sure that all the pictures you want retained are correctly enclosed in zones with the zone type Graphic. These have black borders and display a graphic icon. See Specifying zone types on
If you deselect this, the contents of graphics zones are ignored.
Pictures will neither appear in Text view nor be available for export.
In the lower part of the panel you specify the resolution for graphics exported in grayscale or color. Exported graphics appear as they do in
Text view (black-and-white, grayscale or color).
Reject Character
Words containing unrecognizable characters appear in red in the
Proofread OCR dialog box and optionally in Text view. Unrecognized characters are replaced by a red reject character. The default character is a tilde (~). Type the character you want to use in the Reject Character edit box.
For example, if OmniPage Pro could not recognize the J in REJECT, and the tilde ( ~ ) was the reject character, the string RE ~ ECT would appear in your recognized document.
Retain Graphics settings

Main Language
The Main Language pop-up menu enables you to choose the main language for the page(s) you intend to recognize. Your choice determines which characters are validated for recognition and which main dictionary will be used.
The languages available are Danish, Dutch, English (UK and US),
Finnish, French, German, Italian, Norwegian, Portuguese (Standard and Brazilian), Spanish and Swedish.
Additional Language(s)
In addition to the Main Language for recognition, you may select one or more secondary languages. Specifying additional languages broadens the range of accented letters validated for recognition. It also enables more than one dictionary. Then the program monitors text as it is recognized to determine its language and which dictionary to apply. This lengthens the processing time, so you should only activate additional languages if your pages really contain more than one language.
The Main Recognition Language is displayed on the OCR Toolbar. It is followed by three dots if any additional languages are selected.
t To select secondary languages and dictionaries:
1. Click the Select... button to the right of the Additional
Language(s) display. The Select Secondary Languages dialog box appears displaying all the available languages, except the current main language.

User dictionaries on page 101.
Use Language Analyst
Select Use Language Analyst to have dictionaries and other linguistic aids used during recognition. Proofing will then stop on all doubted words, and the Language Analyst may suggest replacement words.
This is similar to the automatic spell-checking feature in many word processors. If this is selected, marking is available in Text view for all doubted words – those with rejected or questionable characters and those not found in a dictionary.
If you deselect Use Language Analyst, proofing will stop only on words containing unrecognizable characters, and only these words will be available for marking (in red) in Text view. OmniPage Pro can handle almost sixty more languages than those directly selectable (see the list
in Supported languages on page 110). To read these languages, you
must deselect Use Language Analyst.
Choose other options to decrease the number of words the Language

Applying and editing zone styles
Specifying the style set
A style set determines the appearance of the recognition results for each recognized page. The program is supplied with seven built-in style sets and users can create their own custom style sets.
Each style set contains one or more zone styles . A zone style defines formatting elements such as fonts, text flow, alignment and indentation to be used for text within any zone the zone style is applied to.
OmniPage Pro X User’s Guide 87
The following tables give an overview of the built-in style sets and the zone styles offered by each of them.
Four of these style sets define basic formatting levels. These cannot be deleted and allow only limited editing. They are useful mainly for processing documents automatically or for applying standard formatting during manual processing.
The remaining three built-in style sets can be considered samples.
They can be edited and deleted. These style sets can accept new zone styles and allow the zone style values to be changed. These are useful for reformatting documents, mainly during manual processing.

90 Customizing OCR
Specifying a global style set
Select a style set from the Style Set pop-up menu in the OCR
Toolbar. The selected style set is applied to all incoming pages until you change the setting. A new setting here has no effect on existing pages, even if you re-recognize them. t To modify the style set for a page:
Make Image view active. The Zone Info palette appears.
Select the desired style set in its Style Set for Page pop-up menu.
The zone styles available for the page may change.
If the page has already been recognized, you will have to recognize it again for the new style set to take effect.
Creating style sets
You can create and use custom style sets. This is useful for imposing consistent formatting on particular types of documents.
For example, if you often recognize recipes, you can design your own style set that contains a zone style for the recipe title, a style for the list of ingredients, and a style for the directions. You can then use this style set for all the recipes you recognize, even if the original pages have different layouts and formatting.
Note OmniPage Pro X is shipped with three sample style sets, for instance Article. You can use this as a guide when you create zone styles for your new style set. See
page 95 for instructions on editing style sets.
t To create a style set:
Choose Style Sets...
in the Edit menu.
A dialog box appears displaying all available style sets.
Chapter 5
Click New . The New Style Set dialog box appears.
Enter a name for your style set.
For example, you could enter Bibliography as the name if you are creating a style set for handling bibliographies.
Click New .
The Edit Style Set dialog box appears. Your new style set will inherit its behavior from the style set Similar Formats. That means text is decolumnized, but original column widths can be maintained and frames are not used. Auto Detect is the only zone style automatically created.
Add zone styles and define their properties as described in the following section.
Applying and editing zone styles
Much like applying styles to paragraphs in your word processor,
OmniPage Pro allows you to apply zone styles to individual zones.
The zone styles specify how text from each zone should be formatted.
Style sets and zone styles can be selected in the Zone Info palette. You can use only one style set for each page in a document. However, different style sets can be used for different pages in the same document.
Applying and editing zone styles 91

Note Shortcut for applying zone styles
Hold the mouse button down while the mouse pointer is over a zone. A menu of all the zone styles in the current style set is displayed. Select the style you want to use for that zone. If the style set for the page only contains one style, no menu will appear.
Customizing OCR t To apply styles to new zones:
There are two ways of doing this. Decide which you prefer:
• Draw a zone. It will inherit the zone style and other properties of the last selected zone. If more than one zone is selected, the zone style is taken from the first zone in the selection.
• Make sure no zones are selected. Select the desired zone style and other properties in the Zone Info palette. Draw the zone.

Click Done in the Style Sets dialog box if you do not want to edit any other style sets.
Font mapping
If Auto is selected as the font setting for a zone style, OmniPage Pro analyses the text styling inside the zone and assigns it to one of four categories. More than one text category may be detected within a single zone. Each category is mapped to a font which you can specify. u u
Proportional Serif
Character widths vary and short lines finish off letter strokes. This text is an example of this font type. The default font is Times.
Proportional Sans-Serif
Character widths vary; letter strokes do not have finishing lines.
The default font is Helvetica .
Chapter 5 u u
Monospaced Serif
Character width is the same for each character; short lines finish off the letter strokes. The default font is Courier .
Monospaced Sans-Serif
Character width is the same for each character; letter strokes do not have finishing lines. The default font is 0RQDFR .
Note
Font mapping is not applicable to the Plain Format style set. It is always performed with the style sets Similar Fonts, Similar Formats or True Page. It is available but not compulsory for editable style sets.
Note
To avoid font mapping during manual processing, specify a font name for a zone style in place of Auto. This font will be applied to all text in all zones with this zone style. To avoid font mapping in automatic processing, select an editable style set, define a zone style with a specific font name instead of Auto, make this the default zone style and then choose the style set in the OCR Toolbar before starting the automatic processing.

Zone templates
You can use a zone template to quickly and efficiently create zones on documents that have the same zoning requirements. For example, if you frequently process documents with layouts and content that require the same type of zoning, you can create and save a zone template and apply it to all such pages or documents.
A zone template can have up to 64 zones. It remembers the size, position, order, type, style and contents of zones.
t To save a zone template:
Create the desired zones on a page image, manually or automatically with checking and modification as required.
See Creating zones automatically on page 40.
Choose Save Zone Template... in the File menu.
The Save Zone Template dialog box appears.
Type a name for your file and click Save.
The zone template file is saved in the Zone Templates folder within your installation folder. t To apply a zone template to future pages:
• Select the zone template you want to use in the Original Layout pop-up menu on the OCR Toolbar.
OmniPage Pro places template zones on all incoming page images while the template remains in effect.
t To apply a zone template to an existing page:
Make sure the desired template is selected in the Original Layout pop-up menu on the OCR Toolbar.
M ake Image view active, with the desired page displayed.
Click the Apply Template tool in the Zone Info palette.
Chapter 5 t To remove a zone template:
• Select a non-template setting in the Original Layout pop-up menu on the OCR Toolbar.
OmniPage Pro will no longer place template zones on incoming page images. This does not remove template zones from existing zoned pages. Just delete or modify them or choose Discard Current
Zones and Find New Zones in the Zoning Instructions dialog box.
Training OCR
You can create a training file to handle characters that are being consistently misrecognized. A training file is a set of up to 256 prerecognized character shapes each linked to an OCR solution.
OmniPage Pro compares the stored shapes with those encountered on incoming documents.
OmniPage Pro X is a powerful, pre-trained OCR product. For recognizing ordinary characters in everyday fonts, training files should not be needed. Training is useful mainly for long documents (or a set of documents) in which a few character shapes are being repeatedly misrecognized in the same way. Training is not useful for poorly formed characters unlikely to occur again in the document. For instance, a character shape damaged by spots on the image is a poor candidate for training. Do not attempt to create a training file for an unsupported language or alphabet.
t To create a training file:
Open an image file or scan a page that includes the characters you want to train or use a page you have already recognized.
If you select a recognized page, its recognition results are deleted.
Accept the invitation that appears when you finish, to re-recognize the page with the new training file.
Create or modify zones on the page image if you want to train characters from only part of the page.
Select Train OCR as the option in the OCR pop-up menu.

Dictionaries are used to assist recognition and provide suggestions during proofing. A user dictionary is a personal dictionary that you build and customize, to supplement a built-in main dictionary.
Entries for a user dictionary must consist of 2 to 32 characters, without spaces or control characters, such as tabs. The program is supplied with one empty user dictionary, named User Dictionary.
t To create or edit a user dictionary:
Choose User Dictionaries...
in the Edit menu. The User
Dictionaries dialog box lists all user dictionary files.
Do one of the following:
• Select a file and click Open to edit an existing user dictionary.
• Click New to create a new user dictionary. Enter a name in the dialog box that appears and click New .
The Edit User Dictionary dialog box appears.
The words in an existing user dictionary appear in the list box. No words are listed for a new dictionary.
Add or delete words as desired:
• Type a word in the New Word edit box and click Add to add it.
• Select a word in the list box and click Delete to delete it.
• Click Delete All to remove all words from the dictionary.
• Click Import...
to add all words from a specified plain text file, with each word on a separate line.

Troubleshooting
Solutions to try first
Try these solutions if you experience problems starting the program: u u
Ensure that your system meets all requirements listed under System
Make sure that your scanner is plugged in and that all cable connections are secure.
u u u u u
Turn off your computer and your scanner, turn your scanner back on, and then restart your computer. Make sure other applications are functioning properly.
Use the software that came with your scanner to verify that it is working properly before using it with OmniPage Pro.
Make sure you have the correct and up-to-date drivers for your scanner, printer and video card. See the Scanner Guide on
ScanSoft’s web site for more information.
Delete the file ’OmniPage Pro X Prefs’ if unsuitable settings are generating error messages or problems. The program will create a new preference settings file with default values.
Run Disk First Aid to check your hard disk for errors. See
Macintosh Help for more information.
Low memory situations
u u u u
OmniPage Pro may run slowly or poorly under low-memory conditions. Try these solutions if you get low memory warnings:
Restart your computer.
Close other open applications to release memory.
Increase the amount of free hard disk space.
Increase your computer’s physical memory (RAM).
Chapter 6 u Do not scan in color unless you need colored graphics in your output files. Prefer Web color or 256 colors (8-bit pixel depth) rather than True color (16-bit depth) or similar choices.
t To adjust preferred memory size for an application under OS 9.X:
Make sure OmniPage Pro X is closed.
Select OmniPage Pro X under Components in the program folder.
Select Get Info then Memory from the File menu of the Finder.
Adjust Preferred Size under Memory Requirements.
Low disk space situations
u u u
Problems may occur if your system runs low on free disk space. Try these solutions for low disk space situations:
Empty the Trash.
Close all open applications that are not immediately needed.
u
List your OPD files. Delete any you no longer need. Open OPD files and save their recognition results as desired, then delete them.
OPD files tend to be large, especially if they contain color pages.
To keep OPD files as a document archiving system, consider transferring them to a ZIP drive or another mass storage device.
Delete files that are no longer needed. Transfer large but seldom used files to backup storage.
u Run Disk First Aid (in the Utilities Folder) to check for errors that may be using disk space. See Macintosh online Help.
Improving accuracy
Try the following solutions if accuracy is lower than you expected.
Acquire high-quality images u In general, try to use original pages when scanning documents.
High-quality typeset pages yield the best OCR accuracy.
Troubleshooting 105
106 Technical information u u u u u u u u
With low-quality originals, sometimes a good-quality photocopy can yield better OCR results. This may be true for documents with low contrast or printed on thin paper. On the other hand, poor-quality photocopies with stripes, blotches or uneven brightness will usually give worse results.
Page images should be free of notes, lines, doodles or spots.
Anything in a text zone that is not a printed character slows recognition. Exclude such marks from text zones, or enclose them in Ignore-type zones or use the eraser in the Tools palette to delete them from the image.
Check the glass, mirrors, and lenses in your scanner for dust, smudges, or scratches. Clean if necessary.
If your only criteria is OCR accuracy, prefer black-and-white scanning for good quality documents with crisp black text on a white background. Choose grayscale scanning if you are scanning pages with text on colored or shaded backgrounds, or for degraded documents with low or varied contrast.
Adjust the brightness and contrast sliders in the Scanner panel of the Preferences dialog box, or on the scanner’s own interface. Or choose Auto-brightness, if available. Experiment with different settings combinations to get the desired results. See how to
optimize brightness on page 79.
Text in page images should be reasonably clean and crisp.
Characters should be separated from each other and not blotched together or overlapping. Characters distorted by marks or smudges may be unrecognizable.
If you have influence over the styling used in documents you want to recognize, avoid having underlines used. It is difficult to recognize underlined text because the underline changes the shape of descenders on the letters q, g, y, p, and j.
Check the image resolution by selecting Show Page Info from the
File menu. The ideal resolution for OCR is 300 dpi. Images with
200 to 250 dpi or more than 400 dpi are liable to yield lower
Chapter 6 accuracy. The program will not open image files with resolutions below 200 dpi. If this happens and you have the documents on paper, scan them again with better settings.
Ensure zones are suitable u Look at the original page images and ensure that all required text areas are enclosed by text zones. If an area is not enclosed by a zone, it is generally ignored during OCR.
u u
Make sure zone borders do not cut through text and the graphics are correctly zoned. Resize zones as necessary.
Make sure text zones are specified correctly. Change zone types, zone contents, or zone styles as necessary, and perform OCR on
the document again. See Specifying zone types on page 41.
u u u
Be sure you do not have an unsuitable zone template loaded by mistake. If zone borders cut through text, recognition is impaired.
Be sure the original layout option you selected best describes your incoming pages because this influences auto-zoning.
To retain handwritten text, such as a signature, specify it as a graphic zone and be sure Retain Graphics is specified.
Use suitable recognition settings u Make sure the correct main recognition language is selected in the
Spelling panel of the Preferences dialog box. Select secondary languages only if the document really contains them. A flood of blue words in Text view suggests an incorrect language choice.
u u
Check in the OCR panel that Dot Matrix is not selected for
Character Type, unless the document really contains draft-mode
9-point dot-matrix text.
Use the Train OCR mode, or use a suitable existing training file.
This is most likely to help with stylized fonts or uniformly
degraded documents. See Training OCR on page 97.
Troubleshooting 107
108 Technical information u u u u
If you are getting poor results with a training file loaded, check its contents by clicking Training Files... from the Edit menu. Make sure the training file is appropriate for the current document. If it is not, either unload it or edit its contents to remove training from poorly formed character shapes. Unsuitable training can yield worse results than no training at all.
If proofing is skipping too many unsuitable words, be sure Use
Language Analyst is enabled. If you have a user dictionary loaded, check its contents by choosing User Dictionaries... from the Edit menu. Delete entries added in error, especially misspelled words.
If the recognition results do not appear in Text view as you expected, consult the Zone Info palette to check that your style set selection is appropriate. Check that the zone styles are suitably assigned and defined. See chapter 5.
With the True Page style set, recognized text is put into frames
(formatting boxes). Some text may be hidden if a frame is too small. You can see a plus (+) sign in the bottom right corner of the frame in this case. To view the text, place the cursor in the text frame and use the arrow keys on your keyboard to scroll to the top or bottom of the frame. Reduce the point size of framed text to make the whole text visible, or resize the frames in your target application, or choose Remove Frames on Export in the Export dialog box.
Improving fax recognition
Try these solutions to improve OCR accuracy on fax images: u Ask senders to use clean, original documents if possible. Sans serif fonts are easier to recognize than serif fonts.
u u
Ask senders to select Fine or Best Mode when they send you a fax.
This produces a resolution of 200 x 200 dpi.
Ask senders to transmit files directly to your computer via fax modem if you both have one. You can save fax images as image files and then load them into OmniPage Pro. See Loading image
files on page 36 for more information.
Chapter 6
Interface problems and solutions
The Start button is disabled.
Be sure Train OCR is not selected in the OCR pop-up menu.
Training can only be done on a single page at a time.
The Save button in the Preferences dialog box is grayed.
Change a setting in one of the panels, then it will become available.
The Verify window refuses to appear.
Keep this window open or close it; do not minimize it. If it remains minimized, it cannot jump to a new location.
Image view has disappeared completely.
Drag the splitter between the two views to the right.
The table editing tools in the Tools palette are grayed.
These become available only if the current page contains a table zone.
The Export pop-up menu offers no choices.
You are probably using Direct OCR, which places the value To
Application. The pop-up menu becomes available again only when recognition results have been placed in the target application.
System failure during OCR
u u u
Try these solutions if a system failure occurs during OCR or if processing takes a very long time:
Resolve low memory or low disk space problems.
Check the quality of the images you are recognizing.
u
Consult your scanner documentation on ways to improve the quality of scanned images.
Break complex page images (lots of text blocks and graphics or elaborate formatting) into smaller jobs. Draw zones manually or modify automatically created zones and perform OCR on one page area at a time.
