If the Complex Structure of a Paper Document Is Not

Reproduced

Before running the document recognition process, ABBYY FineReader conducts an analysis of the

logical structure of the document and detects areas containing text, pictures, tables, and barcodes.

The program then relies on this analysis to identify the area s and the order in which they are

recognized. This information helps recreate the formatting of the original document.

By default, ABBYY FineReader will analyze documents automatically. However, in the case of very

complex formatting some areas may be detected incorrectly and you may wish to correct them

manually.

Use the following tools and commands to correct areas:

 Manual area adjustment tools on the Image window toolbar.

 Shortcut menu commands available by right–clicking the selected area in the Image

window or the Zoom window.

 Commands on the Area menu.

Restart the OCR process after making the desired adjustments.

Recognition settings, area properties and saving settings also have an effect on how well the layout

of the original document is retrained. For details, see the following sections: "OCR Options,"

"Adjusting Area Properties," and "Saving OCR Results."

If Areas Are Detected Incorrectly

ABBYY FineReader analyzes page images before recognition and detects different types of areas on

these images, such as Text, Picture, Background Picture, Table, and Barcode areas. This

analysis determines which areas will be recognized and in what order. In the user interface,

different area types are distinguished by the colors of their borders.

If you click on an area, it will be highlighted and will become active. You can also navigate areas by

pressing the Tab key. The areas' numbers determine the order in which they are selected when the

Tab key is pressed. By default, these area numbers are not visib le in the Image window, and only

appear if the Order Areas tool is selected.
