Syntax

C++/CLI

Python

public MRZCodeDetectionCommand()

public: 
MRZCodeDetectionCommand();

__init__() # Default constructor

Remarks

The MRZCodeDetectionCommand automatically finds an MRZ zone in a document image.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing; 
using Leadtools.ImageProcessing.Core;

   //Detect MRZ zone 
   MRZCodeDetectionCommand command = new MRZCodeDetectionCommand();
