Below is example how to draw Bar code with text surrounded by code. (script in AutoIt)

; ----------------------------------------------------------------------------------------------------------------

$oQP.SetOrigin($__QPDF_SORIGIN_TopLeft);

$oQP.SetMeasurementUnits($__QPDF_MUNITS_Milimeters)

; Get the width of the barcode With a bar width of 0,1 mm

Local $iBarcodeWidth = $oQP.GetBarcodeWidth(0.1, $sText, 1);

; Draw the barcode

$oQP.DrawBarcode($iBarcodeLeft, $iBarcodeTop, $iBarcodeWidth, $iBarcodeHeight, $sText, 1, 0);

$oQP.SetTextSize(11);

Local $iTextWidth = $oQP.GetTextWidth($sText)

Local $iTextHeight = $oQP.GetTextHeight()

$oQP.SetFillColor(1, 1, 1);

; Draw White Box

$oQP.DrawBox($iBarcodeLeft + ($iBarcodeWidth - $iTextWidth) / 2, $iBarcodeTop + $iBarcodeHeight - $iTextHeight, $iTextWidth, $iTextHeight, 1)

; Center the text

$oQP.SetTextAlign($__QPDF_TEXTALIGN_Center);

; Draw the text

$oQP.SetTextSize(10);

$oQP.DrawText($iBarcodeLeft + $iBarcodeWidth / 2, $iBarcodeTop + $iBarcodeHeight, $sText);
