### rows

The row count of the QR Code.

```cpp
int rows
```

### columns

The column count of the QR Code.

```cpp
int columns
```

### errorCorrectionLevel

The error correction level of the QR Code.

```cpp
QRCodeErrorCorrectionLevel errorCorrectionLevel
```

### version

The version of the QR Code.

```cpp
int version
```

### model

Number of models of the QR Code.

```cpp
int model
```

### mode

Identify the first data encoding mode of the QR Code.

```cpp
int mode
```

### page

Identify the position of the particular symbol in the Structured Append format of the QR Code.

```cpp
int page
```

### totalPage

Identify the total number of symbols to be concatenated in the Structured Append format of the QR Code.

```cpp
int totalPage
```

### parityData

The Parity Data shall be an 8 bit byte following the Symbol Sequence Indicator. The parity data is a value obtained by XORing byte by byte the ASCII/JIS values of all the original input data before division into symbol blocks.

```cpp
unsigned char parityData
```

### dataMaskPattern

```cpp
int dataMaskPattern
```

### codewords

The codewords of the QR Code.

```cpp
unsigned char* codewords
```

### codewordsCount

The count of the codewords.

```cpp
int codewordsCount
```
