Data Matrix Rectangular - bwipp/postscriptbarcode GitHub Wiki
The Data Matrix Rectangular symbology is a rectangular variant of Data Matrix.
Variants:
- Data Matrix is the standard square variant of the symbology.
- Data Matrix Rectangular Extension is a variant of Data Matrix Rectangular that provides a greater range of symbol dimensions.
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
^NNN
in 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 -
^ECI000000
to^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.
- 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.
- 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 8x18, 8x32, 12x26, 12x36, 16x36, 16x48. - If columns, rows and version are unspecified the encoder will default to creating a symbol that is the minimum size to represent the given data.
- The raw option denotes that the data field is providing the input as pre-encoded codewords in
^NNN
format, suitable for direct low-level encoding.
