Below you will find a Java code snippet of how you can read and extract data from a passport.
Remember, in order to retrieve the most accurate results, you will want to have a very crisp and clear image so the engine will not have trouble during the process.

Code:

// Set your license
RasterSupport.setLicense(licenseFile, developerKey);

try{
    if(RasterSupport.getKernelExpired()) {
    System.out.println("License NOT Set Successfully");
    }
    else {
    System.out.println("License Set Successfully");
    }

RasterCodecs rasterCodecs = new RasterCodecs();
MRTDReader mrtdReader = new MRTDReader();
String stream = "PASSPORT_IMAGE.jpg";

RasterImage rasterImage = rasterCodecs.load(stream);

OcrEngine ocrEngine = OcrEngineManager.createEngine(OcrEngineType.ADVANTAGE);
ocrEngine.startup(rasterCodecs, null, null, null);

		
mrtdReader.setOcrEngine(ocrEngine);
mrtdReader.processImage(rasterImage);		
mrtdReader.setImproveResults(true);
HashMap<MRTDField, MRTDDataElement> ar = new HashMap<>();
ar = mrtdReader.getResults();

String[] string = mrtdReader.getLines();
		
for (String string2 : string) {
	System.out.println(string2);
}
				
for (Map.Entry<MRTDField, MRTDDataElement> map : ar.entrySet()) {
MRTDField key = map.getKey();
System.out.println(key);
MRTDDataElement value = map.getValue();
System.out.println(value.getReadableValue());
}
		
ocrEngine.shutdown();
}
catch(Exception e)
{
	e.printStackTrace();
	throw new Exception(e);
}

I have created a project using this code for version 20 of our toolkit. The code is essentially the same, however the OCR Advantage engine is now called LEAD. I have also disposed of the RasterCodecs, the RasterImage, as well as the OcrEngine to prevent memory leaks.

Note that you will have to set your license in the DemoUtilities.java file located in C:\LEADTOOLS 20\Examples\Java\Common.

You can find the project zip attached here:
