Ignore exterior zone
As an alternative to windowing templates, you can use the option
Ignore exterior zone. That way, you can define one particular area
on the page that needs to be OCRed. Any data outside the OCR area
will be excluded from recognition.
Operation
 Select Ignore exterior zone by clicking the corresponding
button on the image toolbar.
 Draw a frame around the part of the page you want Readiris to
recognize.
The part of the page you select will be analyzed automatically.
You will be prompted whether you want to ignore the same exterior
zone for all pages of the document.
To cancel this function, re-execute Page Analysis by clicking the
Analyze page button on the image toolbar.
