Manual Layout and Viewing the Image

You have an opportunity to preview and change the CuneiForm - made decomposition of the image before the recognition. This is very useful when default Automatic Layout does not produce the desired decomposition of the original image.

An incorrect decomposition may lead to recognition errors. The examples of this situation may be found when trying to scan and recognize complex tables, catalogs with a lot of graphics intermixed with text, etc.

In these cases you can activate Manual Layout option and see whether Automatic Layout did a proper decomposition of the page.  If not, then you can use Split (Cut), Merge, Delete and Create to correct manually an automatic page decomposition.

Manual Layout will always overwrite the results of the default Automatic Layout.

Mark the Manual Layout check box in the Recognition Options to select it. At the first step of recognition CuneiForm automatically lays out (decomposes) an image into text and non-text blocks such as headers, paragraphs, pictures, etc. If the Manual Layout option is chosen, the page image will be shown with the blocks selected in it. Each text block is enclosed by frame.

Each text block will be recognized later. All the text blocks not enclosed into a frame will not contribute  any text in final recognition. It is possible to create, delete and change blocks manually. Using the buttons or menus you can:

Create a new block;

Merge blocks;

Delete blocks;

Split a block vertically or horizontally.

When manual layout is complete click [image] button, or press Enter.

To familiarize with the Manual Layout functions you can: press F1 key and the description of the currently selected menu item will upper on screen, or click [image] button and then click the necessary button on the toolbar.
