MrzProcessingParams Object (IMrzProcessingParams Interface)
This object provides access to parameters of the machine-readable zone (MRZ) extraction.
|Application||Engine, read-only||Returns the Engine object.|
Specifies the MRZ format by the MRZ standards.
The default value is MF_Auto.
Specifies the minimum number of characters in the MRZ line. The value can be in the range of 1 to 44. The default value is 28. If the MRZ lines are shorter than the threshold set by this property, the system will not extract a valid MRZ from such an image.
The standard MRZ line length is specified in the ICAO Document 9303 and depends on the type of the document:
We recommend leaving the default value of 28 characters for standard documents. It allows recognizing the MRZs from all three types of documents and has a margin of two characters in case the image is a bit cropped.
If you need to extract the MRZ with more than two symbols lost due to crop or bad image quality, try setting this property to a lower value.
Note: With a lower MinMrzLineLength value, it is more likely that some garbage will be recognized as MRZ.
This object is passed as an input parameter to the ExtractMrz method of the FRPage object.
This object is the output parameter of the CreateMrzProcessingParams method of the Engine object.
