<p>The library includes a command line utility as an additional example on how to use
the library.</p>
<p>
</p><div class="itemizedlist"><ul class="itemizedlist" type="disc"><li class="listitem">
<p><code class="filename">mkbarcode.php</code></p>
</li></ul></div><p>
</p>
<p>This utility can be found in the "<code class="filename">barcode/</code>" directory. This
utility should be used from the command line as the following example shows</p>
<p>
</p><pre class="screen">$>php mkbarcode.php -b code39 ABC123 > barcode.png</pre><p>
</p>
<p>The line above will create a barcode from the data string "abc123" using the Code
39 symbology and store the resulting image in the file
"<code class="filename">barcode.png</code>".</p>
<p>Using the command utility as above assumes that the client version of PHP is
available at the command line. </p>
<p>This utility has the following syntax</p>
<p>
</p><pre class="screen">mkbarcode.php -b <symbology> [-r -h -c -o <output format> -m <width> -s <scale>\\
-y <height> -f <filename> ] datastring
Create the specified barcode
-b What symbology to use, one of the following strings (case insensitive)
UPCA
UPCE
EAN128
EAN13
EAN8
CODE11
CODE39
CODE128
CODE25
CODEI25
CODABAR
BOOKLAND
-c Add checkdigit for symbologies where this is optional
-o Output format. 0=Image, 1=PS, 2=EPS
-m Module width
-s Scale factor
-h Show this help
-f Filename to write to
-r Rotate barcode 90 degrees
-y height Set height in pixels
-x Hide the human readable text
--silent Silent. Don't give any error mesages
</pre><p>
</p>
<p>If no filename is given the image will be sent back to the console which means it
should be redirected to a file.</p>
