General information on page layout analysis

Page layout analysis can be carried out both automatically and manually. In most cases,

FineReader manages the complex task of page layout analysis by itself. Start automatic analysis by

clicking on the

2Read button. Recognition and layout analysis are performed simultaneously.

Note: A standalone page layout analysis procedure is also available (Process>Analyze

Layout

menu). You may run this standalone procedure if needed, but note that here page

layout analysis quality may be inferior, as the coupled layout analysis/recognition procedure

uses additional information acquired during recognition to aid layout analysis.

You may wish to draw blocks manually if:

1. Only part of a page is to be recognized;

2. Automatic layout analysis has resulted in blocks being drawn incorrectly.

Tip: z In some cases automatic layout analysis quality may be improved by altering

the page layout analysis options. To view the current layout analysis options:

Recognition tab, Tools>Options menu.

z If the application has drawn some blocks incorrectly, it is often faster to edit

the incorrect blocks using the block editing tools than to delete the blocks

and draw them manually again.

Block types

Blocks are image areas enclosed in frames. They tell the system which image areas are to be

recognized and in what order. The blocks also influence the way in which the original page

layout is retained. Different types of blocks have differently colored frames. Block frame col

ors can be changed on the

View tab of the Options dialog (Tools>Options menu) in the

Appearance group. Select the required block type in the Item field and the color you want

in the

Color field.

The following block types are available:

Recognition Area – this block type is used for automatic recognition and analysis. After

you click the

2Read button, all blocks of this type will be automatically analyzed and rec

ognized.

Text – this block type is used for text image areas and should only contain text formatted

in one column. If there are pictures inside the text, draw separate blocks around them.

Table – this block type is used for table image areas or for areas of text structured in a

table. When the application reads blocks of this type, it draws vertical and horizontal sepa
