OmniPage Direct adds the power of OCR directly to any Macintosh word-
processing, spreadsheet, or communications program. Working within
your application, you simply choose OmniPage Direct in the Apple menu.
Scanned text then appears in your document just as if you had typed it

point and click to recognize a single paragraph or multiple pages.
After running the Installer program on Disk 1, Direct will appear in the
Macintosh Apple menu.
Scanning text is as easy as pulling down the Apple menu and choosing
Direct. The Scan text dialog box lets you scan immediately or set options
for special features such as recognizing parts of a page or different
languages.
This tutorial guides you through the simplest scan and also explains how
to use the Partial Page features.
This chapter explains every command and setting within Direct. Topics
are listed alphabetically.
This chapter tells you the tricks for speeding up Direct and for improving
text-recognition accuracy. It explains how to recognize text from poor-
quality documents such as multiple-generation copies and newspaper
pages. Adjusting the Brightness setting is the easiest way to improve text-
recognition accuracy.
