Chapter 2 Introduction to OmniPage Web You probably have documents lying on your desk that you would like to share with the rest of your company, or, perhaps, the rest of the world. You could photocopy the information and mail it to anyone who might be interested, or you could retype it and hand-code it in HTML format. Neither of these is an appealing option. OmniPage Web offers a smart solution to increase your productivity and the visibility of your documents.
What Is Optical Character Recognition (OCR)? What Is Optical Character Recognition (OCR)? Optical character recognition (OCR) is the process of turning an image into computer-editable text. An image is an electronic picture of text such as a scanned paper document or an electronic fax file. Images do not have editable text characters; they have many tiny dots (pixels) that together form a picture of text. During OCR, OmniPage Web analyzes an image and defines characters to produce editable text.
Basic Steps of Creating a Web Page Basic Steps of Creating a Web Page These are the basic steps of OmniPage Web’s HTML-conversion process. 1 Bring a document image into OmniPage Web. You can scan a paper document or load an image file. The resulting image appears in OmniPage Web’s image view. See “Bringing Document Images into OmniPage Web” on page 24 for more information. 2 Create zones to identify areas you want to recognize as text or retain as graphics.
The OmniPage Web Desktop The OmniPage Web Desktop Before a document is outlined, OmniPage Web’s desktop displays the pages of the open document in its thumbnail view, image view, and text view. You can use buttons in the Standard, AutoWeb, and Zone toolbars to perform various tasks on the document. Standard toolbar Zone toolbar The image view displays the current page’s original image. AutoWeb toolbar The thumbnail view displays a picture of each page in the document.
The OmniPage Web Desktop After a document is outlined, OmniPage Web’s desktop displays the document outline in outline view, the original image in image view, and a preview of the HTML document in HTML view. Outline toolbar The image view displays the current page’s original image. The outline view displays an outline of the original document objects. Drag this splitter up or down to resize a view. The HTML view displays a preview of the HTML-formatted document.

Chapter 3 Processing Documents This chapter describes how to work with documents in OmniPage Web, including each step of converting paper documents to HTML. There are different ways to accomplish the same tasks in OmniPage Web. You can use toolbar buttons or menu commands to start procedures. OmniPage Web can perform all steps automatically, or you can start each step individually. You can even do different tasks at the same time.
Ways to Process Documents Ways to Process Documents OmniPage Web instantly turns a paper document into an HTML file that you can publish as a Web page. The basic steps of OmniPage Web’s HTML-conversion process are explained on page 13. The following is a summary of those steps. 1 Bring a document image into OmniPage Web. See page 24 for more information. 2 Create zones to identify areas you want to recognize as text or retain as graphics. See page 27 for more information.
Ways to Process Documents The first wizard screen appears. 3 Answer the question in the first screen and click Next. 4 Continue answering questions in the screens that follow. Automatic Processing Use the AUTO button to process a new document from start to finish or to finish processing an open document. To process your document automatically: Processing Documents 1 Set AutoWeb as the command in the AUTO button’s drop-down list. 2 Set the desired Image, Zone, OCR, Outline, and Export commands.
Bringing Document Images into OmniPage Web Performing Multiple Tasks at Once OmniPage Web takes advantage of your computer’s ability to handle more than one process at a time. You can simultaneously scan, create zones, recognize, and edit documents before outlining. For example, if you scan a multiple-page document, you can draw zones on an image as soon as the first page is scanned and you can edit recognized text as soon as it appears in the text view.
Bringing Document Images into OmniPage Web 4 Click the Image button or choose Scan Image in the Process menu. Pages are scanned in order and combined into one working document. Loading Image Files You can load image files into OmniPage Web. An image file is an electronic picture of text, such as a scanned paper document or an electronic fax, that is saved in an image file format such as PCX or TIFF. If a document is already open, loaded image files are inserted as new pages.
Bringing Document Images into OmniPage Web You can Shift-click or Ctrl-click to select multiple files in the same folder. 5 Click Advanced if you want to select files from more than one folder. • Select a file and click Add to put it in the Selected Files list. • Click Add All to add all files from the current folder. 6 Click Open when you have selected all the files you want to load. Image files are loaded in the order selected and combined into one working document.
Creating Zones for OCR Creating Zones for OCR Page images are displayed in OmniPage Web’s image view where zones are created before OCR. Zones are borders that identify areas of an image that will be recognized as text or retained as graphics. Any part of an image not enclosed by a zone is ignored during OCR and outlining. This is a table zone. It will be kept in a row-andcolumn format during OCR. These are text zones. They will be converted to text during OCR. This is an unzoned area.
Performing OCR on a Document 2 Click the Zone button or choose Auto Zones in the Process menu. OmniPage Web automatically draws zones on the current page in the image view. Each zone has a number indicating its order and a picture indicating its zone type. Performing OCR on a Document Performing OCR converts an image to editable text. This is also referred to as recognizing text. OmniPage Web only recognizes machine-printed characters such as laser-printed or typewritten text.
Proofreading OCR Results Proofreading OCR Results After performing OCR, recognized text appears in the text view where you can proofread the results. Proofreading starts automatically if you chose OCR and Proof as the OCR process command. OmniPage Web marks suspected errors in green and inserts a red “reject” character for any character it cannot recognize. To turn off these color markers, choose Show Markers in the View menu so that it is deselected.
Outlining a Document Modifying Words After performing OCR, you can compare recognized text against the original image to verify that the text was recognized correctly. You can modify the recognized text in the Modify Word dialog box. To modify recognized words: 1 Double-click any word in the text view. The Modify Word window opens and shows a picture of the original word and its surrounding area. This window shows a picture of the original image. Click inside it to enlarge or reduce the picture.
Editing Outline Results 3 Highlight an object and click the appropriate button in the Outline toolbar to make changes to the outline. See the next section, “Editing Outline Results,” for more information. Editing Outline Results After outlining, the original document objects appear in outline format in the outline view where you can edit the results. Use the outline toolbar to change the object hierarchy. The document outline appears in this window.
Editing Outline Results To filter which objects appear in the outline: 1 Click the Filter Objects button in the Outline toolbar to open the Filter Objects dialog box. 2 Select which objects you want to see in the outline. By default, body text is deselected to make the outline easier to read. Select which objects you want to see in the outline and click this button. These are the objects that OmniPage Web looks for in your document during outlining.
Selecting HTML Components Selecting HTML Components You can make your Web site even more usable by adding HTML components. Components are parts of an HTML document that make it interesting and functional, such as a hyperlinked table of contents, copyright notice, or navigation panel. To select and format HTML Components: 1 Click the HTML Options button in the Standard toolbar or choose HTML Options... in the Tools menu to open the HTML Options dialog box.
Working with Documents Working with Documents OmniPage Web’s thumbnail, image, text, outline, and HTML views allow you to look at and work with pages in the current document.

Chapter 5 Customizing Your Web Page OmniPage Web has many features that allow you to create customized Web pages. This chapter describes how to use these features. Please continue reading this chapter for information on these topics: • Making Your Web Page More Effective • Using Themes • Making Your Web Page More Effective • Customizing Zones • Creating User Dictionaries • OmniPage Web’s user dictionaries are saved in the data folder in your installation folder.
Making Your Web Page More Effective Making Your Web Page More Effective Organizing electronic documents is a challenge, but if done well, can allow your Web page visitors to quickly navigate through large amounts of information and cross-reference other topics without having to dig through unnecessary text. Here are some suggestions for making your Web page easy and enjoyable to visit. Organize your Web page to make it quicker and easier for visitors to skim the information.
Making Your Web Page More Effective If your image is dark, make sure you change the text colors to light shades so that they show up, and that you make the document background color dark. Otherwise, if the image fails to load (or takes a long time to load), the text will be unreadable. Include pictures to illustrate your text. • Add images. • Add image maps. • Add links to original images.
Using Themes Using Themes A theme has Web page design attributes including font, page layout, border style, and background. Themes allow you to instantly format your HTML document, and are useful to create consistantly-formatted Web pages. OmniPage Web provides a selection of fun and professional themes for you to use, or you can create and save one of your own. To select a theme: 1 Click the HTML Options button in the Standard toolbar, or choose HTML Options... in the Tools menu. 2 Click Load Themes...
Using Themes To save a new theme: Customizing Your Web Page 1 Open the HTML Options dialog box and select one of the provided themes, or begin selecting your own settings. 2 Click Save Themes... to open the Save Themes dialog box. 3 Type in a file name for the new theme.

Adjusting Page Images Before OCR Adjusting Page Images Before OCR You can rotate and straighten page images in OmniPage Web’s image viewer before zoning and OCR take place. This is recommended to improve OCR accuracy on pages that are not oriented correctly. If you need to rotate or straighten a page, be sure to do so before you create zones because all zones are deleted during these operations. To rotate a page image: 1 Click on the page image to make the image viewer active.
Customizing Zones Customizing Zones Zones are borders created around areas of a page image to identify what will be recognized as text or retained as a graphic during the HTMLconversion process. Zones play a big part in determining outline results. You can create zones automatically, manually, or with a template. See the online Help for more information.
Customizing Zones Reordering Zones The numbered order of zones determines the order in which text will be placed on a recognized page, objects will be placed in the outline, and components will appear in the HTML document. Make sure the zone order is acceptable before performing OCR and outlining your document. To reorder zones: 1 Click the Reorder Zones button. The numbers in the zones disappear. 2 Click within the zone you want recognized first. The number 1 appears in the zone.
Customizing Zones 4 Hold down the mouse button and drag the handle in the direction that you want to enlarge or reduce the zone. 5 Release the mouse button when you are done. The zone border changes to display the modified zone area. Deleting Zones You can delete the current zones if you want to create new zones. You can also delete individual zones that you do not want to process during OCR. Any part of a page image not enclosed by a zone is ignored during OCR.
Customizing Zones Zone Type Every zone on a page has a zone-type setting.
Customizing Zones 2 Click the Zone Properties button to open the Zone Properties dialog box. Close button The settings in this dialog box will be blank if multiple zones with different settings are selected. 3 Select a zone type for the selected zones.
