using microsoft office document

Introduction

Optical Character Recognition (OCR) extracts text and layout information
from document images. With the help of Microsoft Office Document Imaging
Library (MODI), which is contained in the Office 2003 package, you can
easily integrate OCR functionality into your own applications. In
combination with the MODI Document Viewer control, you will have
complete OCR support with only a few lines of code.

Important note: MS Office XP does not contain MODI, MS Office 2003 is
required!
