Constructor Detail

BarcodeQRCode

public BarcodeQRCode(String content,
                     int width,
                     int height,
                     Map<EncodeHintType,Object> hints)

Creates the QR barcode. The barcode is always created with the smallest possible size and is then stretched to the width and height given. Set the width and height to 1 to get an unscaled barcode.

Parameters:

content - the text to be encoded

width - the barcode width

height - the barcode height

hints - modifiers to change the way the barcode is create. They can be EncodeHintType.ERROR_CORRECTION and EncodeHintType.CHARACTER_SET. For EncodeHintType.ERROR_CORRECTION the values can be ErrorCorrectionLevel.L, M, Q, H. For EncodeHintType.CHARACTER_SET the values are strings and can be Cp437, Shift_JIS and ISO-8859-1 to ISO-8859-16. You can also use UTF-8, but correct behaviour is not guaranteed as Unicode is not supported in QRCodes. The default value is ISO-8859-1.

Throws:

WriterException
