QR Code - bwipp/postscriptbarcode GitHub Wiki
The QR Code symbology is a 2D matrix-style barcode symbology that can encode full 256 character extended-ASCII.
Also known as: Quick Response Code.
Variants:
- Micro QR Code is a small QR Code that is used in applications that require a small symbol space.
- GS1 QR Code is a variant of Data Matrix that should be used when encoding data that is in GS1 Application Identifier standard format.
- GS1 Digital Link QR Code is a variant of Data Matrix that should be used when encoding a GS1 Digital Link URI.
- HIBC QR Code is a variant of QR Code that should be used when encoding HIBC formatted data.
- Swiss QR Code is a variant of the QR Code for use with the QR-bill application supporting Swiss payments.
Standards: ISO/IEC 18004, JIS X 0510, ITS - QR Code, AIM ISS - QR Code.
- The data field can contain any extended ASCII data. The default interpretation of data by readers is in accordance with ISO/IEC 8859-1. When supported by the receiver characters from other code pages can be encoded using Extended Channel Interpretation (ECI).
- When the parse option is specified, any instances of
^NNN
in the data field are replaced with their equivalent ASCII value, useful for specifying unprintable characters. - When the parsefnc option is specified, non-data function characters can be specified by escape sequences:
-
^FNC1
: FNC1. Recommendation: Use GS1 QR Code for encoding GS1 AI syntax data. -
^ECI000000
to^ECI999999
: ECI indicators
-
- The eclevel option is used to specify the error correction level:
-
eclevel=L
- Low -
eclevel=M
- Medium (default) -
eclevel=Q
- Quality -
eclevel=H
- High
-
- The fixedeclevel option will prevent the error correction level from being opportunistically raised when a better fix to the current matrix is possible.
- The version option is used to specify the size of the symbol, 1 to 40.
- If unspecified the encoder will select the version of the symbol that is the minimum size to represent the given data at the selected error correction level.
- Deprecated: The suppresskanjimode option will prevent the use of Kanji Mode internal encodation. Some readers erroneously consider a Kanji Mode section as an indication that the affected part of the message should be interpreted using a Shift-JIS character set rather than as a data compaction strategy. There's nothing that can be done other than to disable the use of Kanji Mode data compaction for symbols intended to be read by such broken readers.
-
Deprecated: The format option is used to specify the symbol type, either:
-
full
(default) -
micro
: Use Micro QR Code for Micro QR Code symbols. -
rmqr
: The standard is still in draft.
