Windows are drawn on a displayed image to indicate which text and table zones you want to recognize and which graphics you want to save.
There are three window types: text blocks, graphic zones (containing photos, illustrations etc.) and tables.
A color code indicates the window type: text windows have a yellow border, graphics a blue border and table windows a purple border. (No ôfillö color is used because it would mask the actual color tones of the zone.)
There are three different methods of zoning images: automatic page analysis, manual windowing and the use of fixed layouts.
Drawing or detecting several windows is mandatory whenever a text is arranged in columns.
To decompose all scanned documents automatically, enable the option Page Analysis.
To make Readiris decompose the current page, use the command Analyze Page.
To select windows and modify their sort order, use the Sort command.
Select the document language before executing the page analysis when you are dealing with Asian documents. Specific routines are used for these languages: the interline spacing of Asian documents is in most cases bigger than in Western documents, the text is made up of small icons (ôideogramsö) that could easily be seen as graphic zones in Western documents and the text may run from top to bottom, from right to left.
Tools are available to draw windows manually on the scanned image.
Tip: right-click the mouse (Context menu) and select the command Window - Type to modify the zone type.
Apply page analysis to detect the windows and sort the ones you want to include.
Start drawing a window manually - all windows you didnÆt select are erased.
Specific zoning templates can be stored for future use.
