Chapter 5 - Page Layout Analysis

Note: It is possible to have barcode analysis and recognition carried out automatically, but this option

is not set by default. To enable this option, select the

Look for barcodes item on the Recognition tab

(Tools>Options menu).

Automatic Page Layout Analysis Options

As part of the automatic page layout analysis procedure the following types of blocks are drawn: text

blocks, table blocks, picture blocks, and barcode blocks (note: the latter are only available in the Corpo-

rate Edition).

To start automatic layout analysis (and text recognition) click the

2-Read button. Before clicking this

button, however, select the main layout analysis options: document type and table analysis options.

Document type

In most cases text layout is determined automatically. Automatic detection is performed if the Autode-

tect layout value on the Recognition tab in the Document Type group (Tools>Options menu) is set.

Note that the value is set by default.

To select the document type manually:

● Select the desired type in the Document type group on the Recognition tab in the

Options dialog (Tools>Options menu).

Document types available:

Autodetect layout - (set by default) Text layout is determined automatically. Recognition of all text

types, including multi-column texts, and texts containing tables and pictures, is performed automatically.

Single column - The text is formatted into one column. Use this option if automatic page layout analy-

sis incorrectly determines the text type as multi-column.

Plain text formatted with spaces - The text is formatted into one column and set in a monospaced

font that is uniform in size throughout. In the recognized text left indents are represented by spaces,

each line is made into a separate paragraph, and original paragraphs are separated by means of empty

lines. Useful, for example, when recognizing C++ code printouts or old computer printouts.

Table analysis options

In most cases the application divides tables into rows and columns automatically. If additional tuning of

table options is required, open the

Recognition tab in the Tables group. Change these options if:

● automatic page layout analysis has drawn table rows and columns incorrectly;

● the document contains a large number of simple tables of the same type (i.e. there are no

merged cells or there is always only one line of text per cell).

1. Use the

One line of text per cell option if your table has no (or only a few) black

separators and there is only one line of text per cell. For example:

- this table has only one line of text per cell
