Syntax

Objective-C

C++/CLI

Java

Python

public BarcodeEngine()

- (instancetype)init

public BarcodeEngine()

public: 
BarcodeEngine();

__init__() # Default constructor

Remarks

When an instance of BarcodeEngine is initialized, the BarcodeEngine.Reader and BarcodeEngine.Writer properties will be initialized with a new instance of BarcodeReader and BarcodeWriter classes respectively.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void BarcodeEngine_Example() 
{ 
   string[] imageFileNames =

   Path.Combine(LEAD_VARS.ImagesDir, "Barcode1.tif"), 
   Path.Combine(LEAD_VARS.ImagesDir, "Barcode2.tif") 
 }; 
 
   // Create a Barcode engine 
   BarcodeEngine engine = new BarcodeEngine(); 
 
   // Load the image 
   using (RasterCodecs codecs = new RasterCodecs())
