GetAvailableSymbologies Method

Summary

Gets a list of all the barcode symbologies (types) currently available for reading by LEADTOOLS.

Syntax

Objective-C

C++/CLI

Java

Python

public BarcodeSymbology[] GetAvailableSymbologies()

@property (nonatomic, strong, readonly) NSArray<NSNumber *> *availableSymbologies;

public BarcodeSymbology[] getAvailableSymbologies()

public: 
array<BarcodeSymbology>^ GetAvailableSymbologies();

def GetAvailableSymbologies(self):

Return Value

An array of BarcodeSymbology enumeration members that list all the barcode symbologies (types) currently available for reading by LEADTOOLS.

Remarks

The GetSupportedSymbologies returns all the barcode symbologies (types) supported by LEADTOOLS. Depending on the level of unlocked support and availability of the back-end barcode assemblies, not all of the supported types may be available. For example, if the Leadtools.Barcode.QrRead.dll assembly is missing, QR read support will not be available to your application.

To get a list of the barcode symbologies available for reading, use BarcodeReader.GetAvailableSymbologies and to get a list of the barcode symbologies available for writing, use BarcodeWriter.GetAvailableSymbologies.

To get the friendly name of any barcode symbology, use BarcodeEngine.GetSymbologyFriendlyName.

Example

Java

using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.Barcode; 
using Leadtools.ImageProcessing; 
 
 
public void BarcodeEngine_SupportedAndAvailableSymbologiesExample() 
{ 
   // Show all the supported symbologies 
   BarcodeSymbology[] supportedSymbologies = BarcodeEngine.GetSupportedSymbologies(); 
   Console.WriteLine("{0} Supported symbologies:", supportedSymbologies.Length); 
   foreach (BarcodeSymbology symbology in supportedSymbologies) 
   { 
      Console.WriteLine("{0}: {1}", symbology, BarcodeEngine.GetSymbologyFriendlyName(symbology)); 
   } 
   Console.WriteLine("----------"); 
 
   // Create a Barcode engine to get the available read and write symbologies 
   BarcodeEngine engine = new BarcodeEngine(); 
 
   BarcodeSymbology[] readSymbologies = engine.Reader.GetAvailableSymbologies(); 
   Console.WriteLine("{0} Avaliable read symbologies:", readSymbologies.Length);

   foreach (BarcodeSymbology symbology in writeSymbologies) 
   { 
      Console.WriteLine(symbology); 
   }
