The code sample 'MRZExtraction' demonstrates how ABBYY FineReader Engine 12 can be used for the data extraction from Machine Readable Zones (MRZ). The sample uses the basic objects and methods of ABBYY FineReader Engine 12:

1. Create the Engine object using the InitializeEngine function.
2. Load the MachineReadableZone predefined profile using the LoadPredefinedProfile method of the Engine object.
3. Call the CreateFRDocument method of the Engine object to create the FRDocument object.
4. Add pages from the image file to the document. Use the AddImageFile method of the FRDocument object.
5. [optional] Create the MrzProcessingParams object to set up the MRZ format.
6. Call the ExtractMrz method of the FRPage object to extract data from MRZ.
7. Call the ExportToFile method of the MrzData object to save the extracted data to a file of the specified format. The precompiled sample demonstrates export to XML.
8. Close the FRDocument object using the Close method.
9. Unload FineReader Engine — use the DeinitializeEngine function.
