Leadtools.Forms.Ocr.OcrZoneType.Icr ICR (Intelligent Character Recognition) zone. Handwritten text and numbers.
Leadtools.Forms.Ocr.OcrZoneType.Mrz

MRZ (Machine Readable Zone) zone. Only applicable to passports and identity cards.

Travel passports worldwide are MRPs (machine-readable passports). They are standardized by the ICAO Document 9303 (endorsed by the International Organization for Standardization and the International Electrotechnical Commission as ISO/IEC 7501-1) and have a special machine-readable zone (MRZ). MRZs are usually at the bottom of the identity page at the beginning of a passport. These zones are normally used for passports and identity cards.

MRZ text uses capital letters, digits separated by one or more < characters. For example, P<<FIRSTNAME<<<<<LASTNAME.

Note that currently, MRZ zones are not auto-detected by the engine. Instead, use MRZCodeDetectionCommand to detect the MRZ zone area automatically, if needed, and add an OcrZone object with OcrZoneType.Mrz to the page.

Once a zone with MRZ data is recognized, use the IOcrZoneCharacters to parse the row data.
Leadtools.Forms.Ocr.OcrZoneType.Barcode

Barcode zone.

Note that currently, Barcode zones are not auto-detected by the engine. Instead, you need to use BarcodeReader to detect the barcode zone(s) area automatically if needed and add an OcrZone object with OcrZoneType.Barcode to the page.

This for future use of LEADTOOLS.
Leadtools.Forms.Ocr.OcrZoneType.None No recognition zone.
Leadtools.Forms.Ocr.OcrZoneType.FieldData

Field data zone. For example, the name, address and date fields data in passports and identity cards.

Field data uses capital letters, digits and separators.

Note that currently, Field data zones are not auto-detected by the engine. Instead this should be set manually if a zone is known to contain field data to enhance the recognition results.

Once a zone with field data is recognized, you can use the IOcrZoneCharacters to parse the row data.
Leadtools.Forms.Ocr.NativeOcrZoneType Native zone types.
Leadtools.Forms.Ocr.NativeOcrZoneType.Text Flowing text type zone.
Leadtools.Forms.Ocr.NativeOcrZoneType.Table Table type zone.
Leadtools.Forms.Ocr.NativeOcrZoneType.Graphic Zone containing graphics (Not sure).

Leadtools.Forms.Ocr Assembly Changes from Version 16.5 to Version 17

Note on LEADTOOLS for .NET v17

In LEADTOOLS for .NET v16.5, some assemblies had a dependency on System.Drawing. System.Drawing is the .NET 2.0 assembly used with the Windows Forms and GDI+ platforms. Since LEADTOOLS v17 treats Windows Forms, Windows Presentation Foundation (WPF) and Silverlight as equal citizens, certain types in this LEADTOOLS assembly has been changed to reflect that. For example, properties with System.Drawing.Point type have been changed to use the new Leadtools.LeadPoint type, methods with a parameter of System.Drawing.Rectangle type have been changed to use the new Leadtools.LeadRect type. The following table shows the old 16.5 and corresponding new v17 types:

Old v16.5 Type

New v17 Type

System.Drawing.Point

Leadtools.LeadPoint

System.Drawing.Size

Leadtools.LeadSize

These changes are not listed in the topics below.
