Setup Zoned OCR dialog box

Set up specific zones to be processed during recognition on this dialog box. You can preview the document that is similar in structure to the documents that will be processed, navigate through its pages (if it is a multipage document) and select zones for recognition. During processing the component will try to recognize each zone, and if any text is found it will be assigned to an appropriate RRT. The text can be also saved into a CSV file.
