MICR Magnetic Ink Character Recognition

Magnetic Ink Character Recognition(MICR) is one of the supported fill methods in LEADTOOLS LEAD engine. MICR is used to describe the special numbers and symbols you typically see at the bottom of checks, along with the technology and processes to produce and analyze these characters.

You can recognize MICR fonts using any of the LEADTOOLS OCR engines mentioned above by setting the OcrZone.FillMethod to NativeOcrZoneFillMethod.Micr and then recognizing your page.

The following example shows how to recognize MICR zones:


// Assuming you already added the correct references and the 
// following using statements at the beginning of your class: 
// using Leadtools; 
// using Leadtools.Ocr; 
// *** Step 1: Start an OCR engine 
// We will use the LEADTOOLS OCR Module - LEAD Engine  
IOcrEngine ocrEngine = OcrEngineManager.CreateEngine(OcrEngineType.LEAD); 
ocrEngine.Startup(null, null, null, @"C:\LEADTOOLS23\Bin\Common\OcrLEADRuntime"); 
// *** Step 2: Load the TIF image that contains the MICR document to be recognized 
string imageFile = @"C:\LEADTOOLS23\Resources\Images\MICR_SAMPLE.tif"; 
RasterImage image = ocrEngine.RasterCodecsInstance.Load(imageFile, 1); 
// *** Step 3: Create an OCR page from this image 
IOcrPage ocrPage = ocrEngine.CreatePage(image, OcrImageSharingMode.AutoDispose); 
LeadRect micrLocation; 
// *** Step 4: Add an OCR MICR zone around the MICR font area 
//   Either set the location manually if known. For example, this is for MICR_SAMPLE.tif: 
// micrLocation = new LeadRect(38, 678, 1655, 87); 
//   Or use the MICRCodeDetectionCommand to automaitcally detect the location 
Leadtools.ImageProcessing.Core.MICRCodeDetectionCommand micrCodeDetection = new Leadtools.ImageProcessing.Core.MICRCodeDetectionCommand(); 
micrLocation = micrCodeDetection.MICRZone; 
int zoneIndex = 0; 
OcrZone zone = new OcrZone(); 
zone.Bounds = micrLocation; 
zone.ZoneType = OcrZoneType.Micr; 
// *** Step 5: Recognize 
// *** Step 6: Get the results as text 
string text = ocrPage.GetText(zoneIndex); 
Console.WriteLine("The MICR characters recognized on this check are:"); 
// Optionally, you can use the OcrMicrData helper class to parse the MICR data: 
OcrMicrData micrData = ocrPage.GetRecognizedCharacters()[0].ExtractMicrData(); 
Console.WriteLine("Parsed MICR data:"); 
Console.WriteLine("Auxiliary:" + micrData.Auxiliary); 
Console.WriteLine("EPC:" + micrData.Epc); 
Console.WriteLine("Routing:" + micrData.Routing); 
Console.WriteLine("Account:" + micrData.Account); 
Console.WriteLine("CheckNumber:" + micrData.CheckNumber); 
Console.WriteLine("Amount:" + micrData.Amount); 
// Alternatively you can create an IOcrDocument and add the page to it to save it to 
// any of the supported formats instead 
// *** Step 7: Clean up
