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 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 have 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 |
|
System.Drawing.Rectangle |
Leadtools.LeadRect |
|
System.Drawing.Color |
Leadtools.RasterColor |
|
System.Drawing.Drawing2.FillMode |
Leadtools.LeadFillMode |
These changes are not listed in the topics below.
