Data Matrix - bwipp/postscriptbarcode GitHub Wiki
The Data Matrix symbology is 2D matrix-style barcode that can encode full 256 character extended-ASCII.
Also known as: Data Matrix ECC 200, DataMatrix.
Variants:
- Data Matrix Rectangular is a variant of Data Matrix that uses rectangular symbols.
- Data Matrix Rectangular Extension is a variant of Data Matrix Rectangular that provides a greater range of symbol dimensions.
- GS1 DataMatrix is a variant of Data Matrix that should be used when encoding data that is in GS1 Application Identifier standard format.
- GS1 Digital Link Data Matrix is a variant of Data Matrix that should be used when encoding a GS1 Digital Link URI.
- HIBC Data Matrix is a variant of Data Matrix that should be used when encoding HIBC formatted data.
- Royal Mail Mailmark is a variant of Data Matrix that is used by the Royal Mail postal service on letters and other small mailpieces.
Standards: ISO/IEC 16022, ANSI/AIM BC11 - ISS Data Matrix.
- 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
^NNNin the data field are replaced with their equivalent ASCII value. This is 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 DataMatrix for encoding GS1 AI syntax data. -
^PROG: PROG - Reader programming -
^ECI000000to^ECI999999: ECI indicators
-
- Whenever the data field contains suitable input, the encoder will compress ISO/IEC 15434 structured data (internally using the 05 Macro and 06 Macro codewords.)
- When the dotty option is specified the modules are rendered as dots rather than squares. The dot radius can be adjusted using the inkspread option.
- The columns and rows options are used to specify the size of the symbol.
- The version option can also be used to specify the symbol size, as
version=RxC. Valid options are 10x10, 12x12, 14x14, 16x16, 18x18, 20x20, 22x22, 24x24, 26x26, 32x32, 36x36, 40x40, 44x44, 48x48, 52x52, 64x64, 72x72, 80x80, 88x88, 96x96, 104x104, 120x120, 132x132, 144x144 - If columns, rows and version are unspecified the encoder will default to creating a symbol of the specified format that is the minimum size to represent the given data.
- The c40headerlength option specifies the number of leading characters in the data field that must be stored using C40 encodation.
- The raw option denotes that the data field is providing the input as pre-encoded codewords in
^NNNformat, suitable for direct low-level encoding. -
Deprecated: The format option is used to specify the shape of the symbol, either:
-
square(default) -
rectangle: Use Data Matrix Rectangular for rectangular symbols.
-
- Deprecated: Use Data Matrix Rectangular Extension. The dmre option enables Data Matrix Rectangular Extension symbols based on the ISO/IEC standard, which increases the number of rectangular symbol sizes available.
Identical symbols, automatically sized, the latter showing use of the parse option:
Data: This is Data Matrix
Options:
Encoder: datamatrix
Data: This is ^068ata Matrix
Options: parse
Encoder: datamatrix
Identical symbols with a fixed size:
Data: Fixed size
Options: version=48x48
Encoder: datamatrix
Data: Fixed size
Options: rows=48 columns=48
Encoder: datamatrix
A rectangular symbol with a fixed size:
Data: Rectangular
Options: format=rectangle version=16x48
Encoder: datamatrix
An advanced use containing "hidden data" in the padding codewords as used by some non-standard, "high-security" applications. The technique works by filling the symbol using raw codewords formed from the standard data immediately followed by the non-standard padding data beginning with ^129:
Data: ^066^067^068^142^052^129^161^056^206^101^251^147
Options: version=16x16 raw
Encoder: datamatrix
