<pre>In Reportlab I can do the following code to generate barcode and to get the value of that barcode<o:p></o:p></pre>
<pre><o:p> </o:p></pre>
<pre> barcode=code39.Extended39("123456789",barWidth=0.2*mm,barHeight=8*mm)<o:p></o:p></pre>

<pre> bc = Paragraph("Barcode value: %s" % barcode.value, STYLES['Normal'])<o:p></o:p></pre>
