public QRBill()
```
- Method Detail
  - validate
```
public static ValidationResult validate(Bill bill)
```
    Validates and cleans the bill data.
    The validation result contains the error and warning messages (if any) and the cleaned bill data.
    
    For details about the validation result, see Bill data validation
    
    Parameters:
    
    bill - bill data
    
    Returns:
    
    validation result
  - generate
```
public static byte[] generate(Bill bill,
                              QRBill.BillFormat billFormat,
                              QRBill.GraphicsFormat graphicsFormat)
```
    Generates a QR bill payment part.
    If the bill data does not validate, a QRBillValidationError is thrown, which contains the validation result. For details about the validation result, see Bill data validation
    
    Parameters:
    
    bill - the bill data
    
    billFormat - the bill's output size
    
    graphicsFormat - the bill's output format
    
    Returns:
    
    the generated QR bill (as a byte array)
    
    Throws:
    
    QRBillValidationError - thrown if the bill data does not validate
  - generate
```
public static byte[] generate(Bill bill,
                              QRBill.BillFormat billFormat,
                              Canvas canvas)
```
    Generates a QR bill payment part using the specified canvas.
    If the bill data does not validate, a QRBillValidationError is thrown, which contains the validation result. For details about the validation result, see Bill data validation
    
    The canvas will be initialized with Canvas#setupPage and it will be closed before returning the generated QR bill
    
    Parameters:
    
    bill - the bill data
    
    billFormat - the bill's output size
    
    canvas - the canvas to draw to
    
    Returns:
    
    the generated QR bill (as a byte array)
    
    Throws:
    
    QRBillValidationError - thrown if the bill data does not validate
  - encodeQrCodeText
```
public static java.lang.String encodeQrCodeText(Bill bill)
```
    Encodes the text embedded in the QR code from the specified bill data.
    The specified bill data is first validated and cleaned.
    
    If the bill data does not validate, a QRBillValidationError is thrown, which contains the validation result. For details about the validation result, see Bill data validation
    
    Parameters:
    
    bill - the bill data to encode
    
    Returns:
    
    the QR code text
    
    Throws:
    
    QRBillValidationError - thrown if the bill data does not validate
  - decodeQrCodeText
```
public static Bill decodeQrCodeText(java.lang.String text)
```
    Decodes the text embedded in the QR code and fills it into a Bill data structure.
    A subset of the validations related to embedded QR code text is run. It the validation fails, a QRBillValidationError is thrown, which contains the validation result. See the error messages marked with a dagger in Bill data validation.
    
    Parameters:
    
    text - the text to decode
    
    Returns:
    
    the decoded bill data
