39 * @class QrCodeGenerator
40 * @brief This class provides methods to generate a QR code image.
44 * The %QrCodeGenerator class provides methods to generate a QR code image.
46 * The following example demonstrates how to use the %QrCodeGenerator class.
49 * Tizen::Uix::Vision::QrCodeGenerator qrGen;
52 * qrGen.EncodeToFile("test message", Tizen::Uix::Vision::QR_MODE_UTF8, Tizen::Uix::Vision::QR_ECL_Q, "/mnt/ums/Others/temp.bmp", Tizen::Media::IMG_FORMAT_PNG);
55 class _OSP_EXPORT_ QrCodeGenerator
56 : public Tizen::Base::Object
61 * This is the default constructor for this class. @n
62 * The object is not fully constructed after this constructor is called. @n
63 * For full construction, the Construct() method must be called right after calling this constructor.
67 QrCodeGenerator(void);
70 * This is the destructor for this class. @n
71 * The resources are deallocated by this method.
72 * This destructor overrides Tizen::Base::Object::~Object().
76 ~QrCodeGenerator(void);
79 * Initializes this instance of %QRCodeGenerator. @n
80 * Every application must call %Construct() before calling any other methods of %QRCodeGenerator.
84 * @feature %http://tizen.org/feature/vision.qrcode_generation
86 * @exception E_SUCCESS The method is successful.
87 * @exception E_UNSUPPORTED_OPERATION The Emulator or target device does not support the required feature.
88 * For more information, see <a href="../org.tizen.gettingstarted/html/tizen_overview/application_filtering.htm">Application Filtering</a>.
89 * @remarks Before calling this method, check whether the feature is supported by %Tizen::System::SystemInfo::GetValue() methods.

103 * Encodes a QR code into a file.
107 * @return An error code
108 * @param[in] message The text to encode to QR code image
109 * @param[in] mode The input text encoding format (QR_CODE_MODE_ALPHANUMERIC, QR_CODE_MODE_BYTE, QR_CODE_MODE_UTF8)
110 * @param[in] errorCorrectionLevel The QR code error correction level
111 * @param[in] compatibility The compatibility mode with zxing library for UTF-8 codes mode when mode is selected with QR_MODE_UTF8
112 * @param[in] imageFilePath The file path of the generated QR code image
113 * @param[in] imageFormat The image file format of the generated QR code image

117 * @exception E_INVALID_ARG A specified input parameter is invalid.
118 * @exception E_FILE_NOT_FOUND The specified file cannot be found or accessed.
120 * @remarks QR code encoding for UTF-8 is not standardized as yet.
121 * So we support UTF-8 encoding/decoding compatibility to zxing(http://code.google.com/p/zxing/) library.
