<div class="sect1" title="Principle of Datamatrix Barcodes"><div class="titlepage"><div><div><h2 class="title" style="clear: both"><a name="id2603444"></a>Principle of Datamatrix Barcodes</h2></div></div></div>
<p>Datamatrix (or Data Matrix) is a high density 2 dimensional barcode that can encode up
to 3116 characters from the entire 256 byte ASCII character set. Compared with DF417
barcode symbology the datamatrix barcode belongs to newer family of 2 dimensional
barcodes that makes better use of both dimensions and thus can achieve higher data
capacity than the PDF417 symbology (~3kB vs ~2kB). The symbol is built on a square grid
which have a finder pattern around the edges of the symbol to allow a scanner to
identify the barcode. The finder pattern makes it possible to read the barcode
regardless of the physical orientation of the code.</p>
<p>In the same way as with other 2 dimensional barcodes the datamatrix code includes
error correction capability in order to be resilient towards physical damages of a code.
Originally data matrix used an older convolutional error correction schema (ECC) but
that has later been changed to use a Reed-Solomon type of error correction which is much
more efficient. The older ECC version is known as ECC 000 to ECC 140 and should be
considered obsolete and should not be used in new applications.</p>
<p>The newer error correction schema (with Reed-Solomon codes) is known as ECC 200 schema
and is the current and recommended schema. By default the library will use the newer
schema but support also exists for legacy applications to use the older ECC schema. (See
??)</p>

<p>Even though it is primarily designed to handle the the Western alphabet (ISO-8859/x
code tables) it will support user prepared Unicode characters through the use of the
"Extended Channel Interpretation" (ECI) mechanism. However description of the ECI
standard is out of scope for this manual and the interested reader are referred to the
official ECI standard document.</p>
<p>Datamatrix standard has been adopted by (among others) "The American National
Standards Institute" (ANSI) as a standard symbology and a number of industry standard
associations (e.g. EIA, SEMI, AIAG, ATA) where it has been recommended for use.</p>

<p>Datamatrix is a two-dimensional symbology in the shape of a rectangle. The size
and shape of the symbol is usually chosen either automatically or by the user.
Usually it is chosen to be the smallest size that will have enough data capacity to
encode the given data. The symbol rectangle is build up by square dots whose size
"the module" is also user specified.</p>
<p>The Data Matrix symbol rectangle comes in two basic shapes.</p>
<p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p>It is either a square between the sizes of 10x10 up to 144x144 modules
in even steps</p>
</li><li class="listitem">
<p>It is a rectangle between the size of 8x16 up to 16x48</p>
</li></ol></div><p>
</p>
<p>Examples of the two basic shapes are shown in <a class="xref" href="ch26.html#fig.datamatrix-square" title="Figure 26.2. Datamatrix - Square symbol shape">Figure 26.2. Datamatrix - Square symbol shape</a> and <a class="xref" href="ch26.html#fig.datamatrix-rect" title="Figure 26.3. Datamatrix - Rectangle symbol shape">Figure 26.3.

</p>
<p>The maximum capacity for Data Matrix codes is up to 3116 numeric characters or up
to 2335 alphanumeric characters or up to 1555 bytes of binary information.</p>
<p>The exact number of characters that can fit in a Data Matrix symbol depends on the
actual encoding (or compaction) schema used. In short this is used to more
efficiently encode ASCII characters to fit more data into a fixed number of bytes.
For example if only numeric data is to be encoded then instead of using one byte to
hold each digit two digits is stored in a single byte hence doubling the amount of
data that can be stored in a given number of bytes.</p>
<p>To encode data into a Datamatrix symbol the following (principal) steps are
taken.</p>
<p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p>The input string (which can be any ASCII values between 0-255) is
encoded using the selected encoding or encodings (it is possible to
switch encoding mid-way through the string). The primary purpose of the
encoding is to compress the data into a much shorter form.</p>
</li><li class="listitem">
<p>If needed the data is padded to fill up to the capacity of the
selected symbol size.</p>
</li><li class="listitem">
<p>Once the string has been encoded (and possible padded) a number of
error correcting code words are added so that the data can be recovered
even if part of the printed symbol have been destroyed (perhaps a corner
has been teared off).</p>
</li><li class="listitem">
<p>Finally the encoded data and the error correcting words are placed in
the symbol according to an algorithm specified in the standard. This is
done by placing each bit of every data byte in a specific position in
the data matrix symbol.</p>
</li></ol></div><p>
</p>
<p>The above explanation is by necessity simplified and for those interested into the
specific details we refer to the official standard. It is also possible to review
the code itself to understand the details.</p>
</div>
<div class="sect2" title="Encodation efficiency"><div class="titlepage"><div><div><h3 class="title"><a name="sec.encodation-efficiency"></a> Encodation efficiency</h3></div></div></div>
<p>As explained in the previous section several compaction schema are used to encode
the data to enable more data to fit in a given symbol. Depending on the actual data
there are several compaction schema that can be used in order to achieve the
greatest possible compression. The standard specifies six different schema. The
compaction efficiency are given in <a class="xref" href="ch26.html#table.datamatrix-encodation-efficiency" title="Table 26.1. Datamatrix encodation efficiency">Table 26.1. Datamatrix encodation efficiency</a>. </p>
<p>Depending on the application the user of the library may chose to either select a
fixed encodation mode but it is usually best to let the library automatically select
a combination of encodation schema that will give the smallest possible symbol
size.</p>

<p>As was mentioned in the introduction there are two main subsets of Datamatrix
symbols. Those using convolutional codes for error correction which were used for
most of the initial installations of Datamatrix systems, these earlier versions are
referenced as ECC-000 to ECC-140 (the number specifies the level of convolutional
error correcting code).</p>
<p> This first subset will be commonly referred to as ECC-140 in the remainder of
this manual. </p>
<p>The second subset is referenced ECC-200 and uses Reed-Solomon error correction
techniques. The two subsets have the following characteristic:</p>
<p>
</p><div class="orderedlist"><ol class="orderedlist" type="1"><li class="listitem">
<p>ECC-000 to ECC-140 symbols all have an odd number of modules along
each square side.</p>
</li><li class="listitem">
<p>ECC-200 symbols have an even number of modules on each side. ECC-200
can have non-square symbol sizes.</p>
</li></ol></div><p>
</p>
<p>Hence the type of encoding used is auto-discriminative. The maximum data capacity
of an ECC-200 symbol is 3116 numeric digits, or 2335 alpha numeric characters, in
the largest 144 modules square symbol.</p>
<p>Even though the library supports the creation of both type of Datamatrix symbols
it is recommended that all new applications uses the more modern ECC-200 subset.
This is also the recommendation in the standard. ECC-140 should only be used in
legacy system where old equipment is used which have not be upgraded to handle the
modern ECC-200 subset.</p>

<p>As was mentioned in the previous section the actual data capacity depends on the
symbol size. By default the library will select the smallest possible symbol size
that will encode a given character string with the chosen encoding (possibly
automatic). Table 2 below gives the maximum capacity for the three most common
encoding schema for each symbol size as well as robustness in each symbol specified
as the number of errors (destroyed data) that can be recovered. </p>
