ProcessAtOnce Method

Summary

Analyzes input image by detecting, recognizing, and parsing MRZ code.

Syntax

C++/CLI

Python

public MRZReader ProcessAtOnce( 
   RasterImage image, 
   bool ownImage, 
   CancellationToken ct 
)

public:  
   MRZReader^ ProcessAtOnce( 
      RasterImage^ image, 
      bool ownImage, 
      CancellationToken^ ct 
   )

def ProcessAtOnce(self,image,ownImage,ct):

Parameters

image

A RasterImage reference.

ownImage

A boolean value to indicate whether to use its own image.

A CancellationToken value.

Remarks

This function ignores any feeds received by the Process() function, if any, and takes this frame (passed in the parameter) and uses it as a key frame and will try to parse the MRZ code.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Forms.Common; 
using Leadtools.Ocr; 
using Leadtools.Forms.Commands; 
 
 
 
public void ProcessAtOnceMRZCode(RasterImage rasterImage) 
{ 
   IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD); 
   ocrEngine.Startup(null, null, null, LEAD_VARS.OcrLEADRuntimeDir); 
 
   if (ocrEngine.SettingManager.IsSettingNameSupported("Recognition.RecognitionModuleTradeoff")) 
      ocrEngine.SettingManager.SetEnumValue("Recognition.RecognitionModuleTradeoff", "Accurate"); 
 
   MRZReader reader = new MRZReader(); 
   reader.MRZReaderOCR(ocrEngine); 
   var results = reader.ProcessAtOnce(rasterImage,true); 
 
   if (reader.Results != null) 
   { 
      foreach (var item in reader.Results) 
      { 
         Console.WriteLine("Field name : " + item.Key.ToString() + "Value : " + item.Value.ToString()); 
      } 
   } 
 
   reader.Dispose(); 
}
