</table></dd>
<DT><I>Data</I></DT>
<DD>Specifies the barcode data. Note that some characters may need to be URL-encoded as dictated by the HTTP 
specification. For example, you would use "+" for space " ".
<p>If the barcode type supports check characters, it's not necessary
to include them in the data. 
<p>
If your barcode data contains a native character with no ASCII equivalent, 
you need to use the character whose (ANSI Western/Unicode) code is that of the native character plus 128.
For example, in the Code-128 case, the <i>FNC 1</i> character (native code: 102) would be represented
by the character whose code is 102+128 = 230 (or 0xE6 in hex). To use such a character in a URL,
you need to URL encode it; i.e., you would need to use 0xU00E6 for <i>FNC 1</i>.
<DT><I>AddOnData</I></DT>
<DD>Specifies the add-on barcode data if the barcode type has an add-on barcode.</dd>
<DT><I>ImageFormat</I></DT>

<DT><I>Width</I></DT>
<DD>Specifies the desired width of the barcode in pixels; depending on the <i>orientation</i>,
this may either be the actual <i>image </i>width or height. An alternative way of specifying
the barcode width is to use the <i>BarWidth</i> parameter.</dd>
<DT><I>Height</I></DT>
<DD>Specifies the desired height of the barcode in pixels; depending on the <i>orientation</i>,
this may either be the actual <i>image </i>height or width.</dd>
