New file format with improved image compression
Microsoft Office Document Imaging uses the Microsoft Document Imaging Format (MDI) (Microsoft Document Imaging Format (MDI): A high resolution, tag-based graphics format, based on the Tagged Image File Format (TIFF) used for digital graphics.), a file format based on the Tagged Image File Format (TIFF) (Tagged Image File Format (TIFF): A high-resolution, tag-based graphics format. TIFF is used for the universal interchange of digital graphics.) that is designed to store images by page layout.In general, images that are saved in the MDI file format take up less disk space than the same images saved as TIFF files. The image quality of an image saved in the MDI file format is comparable to that of the same image saved in TIFF.
Support for importing files from other programs
You can import files that were created in other programs directly into Microsoft Office Document Imaging, creating in effect a scanned document from an existing file. You can share files with other people who use Microsoft Office Document Imaging, and even get their comments or feedback in the file, even if they don't have the program that was used to create the file. And you can do this as simply as opening a file.
Support for annotating documents
When you are reviewing a Microsoft Office Document Imaging document, you can use annotations to mark up your document. You can add text as a note or comment, apply highlighting to important text, draw freeform text or shapes to circle text in question, or insert a picture in your document by using the buttons on the Annotations
toolbar.

Picture added as an annotation
Highlighting applied to call out important information
Freeform shape drawn to call attention to a detail
Text added as a comment for a reviewer
You can:
- Move, resize, and remove annotations.
- Select the font and background color (if any) for text you add to your document.
- Choose the thickness and color of ink for the pens you use to add highlighting and drawings.
- Make your annotations a permanent part of your document.
- Print your document with or without annotations.
New page pane views
When you are viewing your document in the page pane (page pane: Displays the page that's selected in the thumbnail pane in a larger size, and enables portions of the page to be selected and copied.), you can select from the following options on the View menu:
- Single page view and scroll through your document one page at a time.
- Continuous Page view and scroll through the pages as one continuous document.
- Two Pages view two pages side-by-side on the screen and scroll through your document two pages at a time.
Optical character recognition (OCR) changes
Optical character recognition (OCR) now includes support for the following:- document layout information such as font type and font size is captured and stored along with the raw text
- pictures and simple tables are recognized
- text in East Asian languages is recognized
In addition, you can now perform OCR on a page by page basis. You can select only the page or pages you want to perform OCR on, or you can perform OCR only on pages that OCR has not been run on yet. This saves you time when you only need to recognize a portion of text in your document, or if you need to recognize text in a different language on only a few pages.
Support for sending documents to a fax service
In addition to sending a document to someone as an attachment in e-mail, you can also send a document to a fax service.
Support for Automation
Microsoft Office Document Imaging supports Automation. A programmer can use a number of different programming languages, for example Visual Basic, C++, or VBScript, to manipulate exposed objects by invoking methods on the object or by getting and setting the object's properties. Office Document Imaging exposes a document object, and a viewer object, so that a program can be written for example to open a Tagged Image File Format (TIFF) or Microsoft Document Imaging Format (MDI) document, change the zoom scale, compression options, and OCR text information.
