Retrieving the Decoded String (Simple)

This code snippet shows how to read a QR code and retrieve the decoded string.

C++

#include <eVision/EasyQRCode/EQRCodeReader.h>

using namespace eVision;


// Image constructor
EImageBW8 srcImage;

// QR code reader constructor
EQRCodeReader reader;

// ...

// Read
std::vector<EQRCode> qrCodes = reader.Read(srcImage);

// Retrieve the data of the first QR code found in best guess mode
std::string decodedString = qrCodes[0].GetDecodedString(EByteInterpretationMode_Auto);

C#

using eVision;

// Image constructor
EImageBW8 srcImage = new EImageBW8();

// QR code reader constructor
EQRCodeReader reader = new EQRCodeReader();

// ...

// Read
EQRCode[] qrCodes = reader.Read(srcImage);

// Retrieve the data of the first QR code found in best guess mode
string decodedString = qrCodes[0].GetDecodedString(EByteInterpretationMode.Auto);
