BankCheckReader Class

Summary

Class for reading BankCheckFields in a bank check image.

Syntax

C++

Java

public class BankCheckReader

Public Class BankCheckReader

public class BankCheckReader

public ref class BankCheckReader

Remarks

This is a general purpose class that can retrieve machine-printed information from bank check images.

It does not read all types of checks and does not always read all fields.

To extract hand-written text from scanned documents and convert images to text-searchable formats, use the LEADTOOLS ICR Module - OmniPage Engine.

Example

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Forms.Common; 
using Leadtools.Ocr; 
using Leadtools.Forms.Commands; 
 
public void TestBankCheckReader() 
{ 
   // Initialize the RasterCodecs class 
   RasterCodecs codecs = new RasterCodecs(); 
 
   // Initialize the BankCheckReader class 
   BankCheckReader checkReader = new BankCheckReader(); 
 
   // The bank cheque image 
   string chequePath = Path.Combine(LEAD_VARS.ImagesDir, "BankCheck.jpg"); 
   RasterImage image = codecs.Load(chequePath); 
 
   IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD, false); 
   ocrEngine.Startup(codecs, null, null, LEAD_VARS.OcrLEADRuntimeDir); 
   // Assign Engine to Reader 
   checkReader.OcrEngine = ocrEngine; 
 
   //Set MICR code type 
   checkReader.MicrFontType = BankCheckMicrFontType.E13b; 
 
   // handle Process Event 
   checkReader.Process += new EventHandler<ProgressEventArgs>(reader_Processed); 
 
   // Process Image 
   checkReader.ProcessImage(image); 
 
   ocrEngine.Shutdown(); 
} 
 
void reader_Processed(object sender, ProgressEventArgs e) 
{ 
   Console.WriteLine(string.Format("State      : {0}%", e.State)); 
   Console.WriteLine(string.Format("Percentage : {0}%", e.Percentage)); 
   Console.WriteLine(string.Format("FieldType  : {0}%", e.FieldType.ToString()));
