Detailed Description

Encoder for QR code.

Encoding happens according to ISO/IEC 18004 international standard for QR Code 2005.

Unsupported Features:

• Kanji mode
• Extended Channel Interpretation (ECI)
• Structured Append
• Micro QR

GS1 QR Code is supported where a FNC1 mode is added as first data element. ASCII GS (hex 1D) may be used as terminator for variable application data fields.

Member Enumeration Documentation

Level

enum BpsQrCode::Level

Error correction levels.

Enumerator
LevelL	Low: up to 7% error correction.
LevelM	Medium: up to 15% error correction.
LevelQ	Quality: up to 25% error correction. This is the initial default.
LevelH	High: up to 30% error correction.

Member Function Documentation

encode()

QVector<QVector<bool> > BpsQrCode::encode	(	const QString &	aText,
		int	aVersion,
		Level	aLevel,
		bool	aGS1
	)

Encode a text into a matrix.

In case of error a empty matrix is returned. Possible errors are invalid version, or text too large to be encoded.

Parameters

aText	The text to encode.
aVersion	The QR code version (1...40) to use, or 0 to automatically use the smallest possible version for the given text and error correction level.
aLevel	The error correction level to use.
aGS1	True to create GS1 QR Code, false to create generic QR Code.

Returns

The encoded text in a bit matrix (2 dimensional array).
