Scanner handling
OCR for Navision can use all scanners with a TWAIN driver. A TWAIN driver is the only requirement needed for the scanning process. All hardware management is done by OCR for Navision. A single call to the OCR codeunit, and your document is scanned and stored in the database.
(We do not support scanning process under Citrix with the current version of OCR for Navision)

Bitmap handling
The scanned documents are stored as TIFF-G4 bitmaps, the only bitmat format that handles multiple pages in the same document. Bitmap are stored either in the Navision database (BLOB fields), or saved on a fileserver.
The codeunit contains functions for preview and printing.

OCR functionality
OCR for Navision uses a neural network for character recognization. This results in different fonts being recognized easily, as long as the characters looks pretty normal. After characters are recognized, the words are compared with the words in the dictionary. You can easily manage the dictionary from Navision, and add your own words, such as items- or suppliers name.

Extraction of data from text
After the text is recognized, OCR for Navision parses the text, and extracts data, using user defined rules. Then the data are ready for further processing. OCR for Navision has a special function to automatically recognize and identify documents, by using predefined rules, and therefore without involving the user.

Language
OCR for Navision reads and understands Danish, English, French, and Dutch. It is only possible to recognize languages sharing the same characters with the previously mentioned languages and then developing language specific dictionaries.

For easy implementation, we include our "Developers Guide" and the demo-database (Financial 2.60), witch provides examples and basic implementation code.
