.
Datamatrix
Introduction
Data Matrix is a two-dimensional
(2D) matrix symbology which is made up of square modules arranged within
a perimeter finder pattern. It can encode up to 3116 characters from the
entire 256 byte ASCII character set. The symbol consists of data regions
which contain square modules set out in a regular array. Large ECC 200
symbols contain several regions. Each data region is delimited by a finder
pattern, and this is surrounded on all four sides by a quiet zone border
(margin).
ECC 200 symbols have an even
number of rows and an even number of columns. Most of the symbols are
square with sizes from 10 x 10 to 144 x 144. Some symbols however are
rectangular with sizes from 8 x 18 to 16 x 48. All ECC 200 symbols can
be recognized by the upper right corner module being light (binary 0).
ECC200 is the newest version
of data matrix and supports advanced encoding error checking and correction
algorithms (reed-solomon). This algorithms allow the recognition of barcodes
that are up to 60% damaged.
The barcode supports two optional
mechanisms:
- The "Extended Channel
Interpretation" (ECI) mechanism enables characters from other character
sets (e.g. Arabic, Cyrillic ..) and other data interpretations or industry-specific
requirements to be represented.
- The "Structured append"
allows files of data to be represented as a secuence of up to 16 Data
Matrix symbols. The original data or file can be reconstructed regardless
of the order of the symbols.
J4L DataMatrix supports:
- All sizes and formats (from
10x10 till 144x144)
- Ascii, text , C40 and Base256
(for binary data) encoding.
- The Extended Channel Interpretation
and Structured append
Formats
RDataMatrix supports all data
matrix formats. The following table contains the size , the capacity and

Encoding
The data represented in the
symbol is can be compressed using one or several of the following algorithms:
- ASCII: it is used to encode
data that mainly contains ascii characters (0-127). It encodes one alphanumeric
or two numeric characters per byte.
- C40: it is used to encode
data that mainly contains numeric and upper case characters. C40 encodes
three alphanumeric data characters into two bytes.
- TEXT: it is used to encode
data that mainly contains numeric and lowercase characters. TEXT encodes
three alphanumeric data characters into two bytes.
- BASE256: it is used
to encode 8 bit values.
All encoding system can be
used to encode any data, but for example, encoding binary data with C40
generates much more overhead (longer symbol) than with BASE256.
Control characters
RDataMatrix uses the character
~ to recognize some special characters in the input data. The following
possibilities are available:
- ~X is used to represent
character values from 0 to 26. Replace the X like in the following
example ~@ = means character ascii 0, ~A= means character 1, ~B=means
character 2, ~C=means character 3 ...
- ~1: represents the character
FNC1. When FNC1 appears in the first position (or in the fifth position
of the first symbol of a Structured Append), it will indicate that the
data conforms to the UCC/EAN Application Identifier standard format.
- ~2: It is used to represent
Structured Append. Structured Append is used to link information from
several symbols in a secuence. The ~2 must be followed by 3 additional
bytes. The first 4 bits of thie first byte identify the position of
the particular symbol in the secuence . The last 4 bits identify the
total number of symbols in the secuence. The second and third byte are
used as a file identifier are can have a value between 1 and 254 (up
to 254*254=64516 identifiers). See Data Matrix Specification for more
information about this (ISO 16022).
- ~3: This character are only
allowed in the first position of the symbol. It indicates that the data
contains commands for the barcode reader.
- ~4: not allowed.
- ~5 and ~6: These characters
are only allowed in the first position of the symbol. If ~5 is used
the header [)> ascii30 ascii05 ascii29 will
be transmitted by the barcode reader before the data in the symbol and
the trailer ascii30 ascii04 will be transmitted after
the data. If a ~6 is used , the header [)> ascii30 ascii05
ascii29 will be transmittedby the reader before the data and
the trailer ascii30 ascii04 will be transmitted afterwards.
- ~7NNNNNN specifies the Extended
Channel to be used, where NNNNNN is a value between and 000000 - 999999.
For example: ~7000010 means Extended Channel 10 . Extended channel is
used for using other character sets other than ascii. See Data Matrix
Specification for more information about this (ISO 16022).
- ~dNNN represents the ascii
character encoded by the 3 digits NNN. For exmaple, ~d065 represents
the character 'A'.
QRCode
QR Code is a matrix symbology
which includes a finder pattern located at three corners of the symbol
used to locate the symbol and figure out its size and orientation.
The main features of QRCode
symbols are:
-
There are 40 sizes of QR
Code symbols (called Version 1, Version 2 till Version 40). Version
1 measures 21 modules * 21 modules, Version 2 measures 25 modules
* 25 modules and so on. Version 40 measures 177 modules * 177 modules.
-
The following data can
be encoded:
-
Numeric data (digits
0-9).
-
Alphanumeric characters
, digits 0 - 9; upper case letters A -Z and nine other characters:
space, $ % * + - . / :
-
Byte data (bytes 0-255)
-
Kanji characters (
hexadecimal values 8140 -9FFC and E040 - EBBF )
-
Symbol size is 21 * 21
modules to 177 * 177 modules (Versions 1 to 40, increasing in steps
of 4 modules per side).
-
The maximum number of characters
encoded in one symbol (without structured append) is:
-
Numeric data: 7089
characters
-
Alphanumeric data:
4296 characters
-
Byte data: 2953 characters
-
Kanji data: 1817 characters
-
Supports 4 error correction
levels:
-
L ( 7% of the symbol
codewords).
-
M ( 15% of the symbol
codewords).
-
Q ( 25% of the symbol
codewords).
-
H ( 30% of the symbol
codewords).
-
Structured append (optional)
This allows files of data to be represented logically in up to 16
QR Code symbols.
-
Extended Channel Interpretation
(optional): enables data using character sets other than the default
set (e.g. Arabic, Cyrillic, Greek).
-
FNC1 indicators: FNC1 mode
is used for messages containing data formatted either in accordance
with the UCC/EAN Application Identifiers standard or in accordance
with a specific industry standard previously agreed with AIM International.
J4L-QRCode supports:
-
QRCode mode 2 symbols (not
mode 1)
-
All versions 1-40. Automatic
selection of the version is also supported.

Aztec
code
Aztec Code is a 2D matrix symbology
made up of square modules on a square grid, with a square bullseye pattern at
their center. Aztec Code symbols can encode large amounts of data with user
defined error correction level.
The smallest format can encode 13
numeric , 12 alphabetic characters or 6 bytes of data, while the largest format
can encode 3832 numeric ,3067 alphabetic characters or 1914 bytes of data.
Compact formats can be used to encode
short messages in a more efficient manner than full range formats. Note that
reader/decoder can autodiscrimanate between both formats.
There are also a set of 256 special
formats called "Aztec runes" which can be used for encoding values
0 to 255 for special applications.
J4l-AztecCode supports:
- All Aztec code formats (compact
and full range).
- Normal and binary encoding.
- Structured append. This allows
you to encode large messages by means of a secuence of symbols.
- Extended Channel Interpretation.
- Reader initialization bit.
- Aztec Runes.
Formats
Available formats are:
| Rows / columns (number of modules/squares) |
Capacity (digits)
|
Capacity (text)
|
Capacity (binary data)

Encoding
The data represented in the symbol
can be compressed using one of the following algorithms:
- NORMAL: can encode any character
but it is not very efficient encoding binary values (values above 128).
- BINARY: use this mode only if
your data contains many bytes/characters above 128.
Control
characters
J4L-Aztec uses the character ~ to
recognize some special characters in the input data (if the processTilde option
has been activated). The following possibilities are available:
- ~~: will be replaced with ~
- ~dxxx: will be replaced by the
character whose ascii code is xxx. For example ~d065 will be replaced with
A.
- ~F: will be replaced with the
FNC1 flag (allowed as first codeword only).
- ~Exxxxxx: will be replaced with
the Extended Interpretation Channel flag xxxxxx. For example to activate Extended
Interpretation Channel 1, use ~E000001.
