barcode4j ENA13 problem

[yanlanglois]

I use the following code :

<componentElement>                <reportElement uuid="64c6102b-4364-4a18-844a-1e14f87db342" stretchType="RelativeToTallestObject" x="14" y="43" width="31" height="67">                    <property name="local_mesure_unitx" value="mm"/>                    <property name="local_mesure_unity" value="mm"/>                    <property name="local_mesure_unitwidth" value="mm"/>                    <property name="local_mesure_unitheight" value="mm"/>                </reportElement>                <c:EAN13 xmlns:c="http://jasperreports.sourceforge.net/jasperreports/components" xsi:schemaLocation="http://jasperreports.sourceforge.net/jasperreports/components http://jasperreports.sourceforge.net/xsd/components.xsd" orientation="90" checksumMode="ignore">                    <c:codeExpression><![CDATA[$F{ean13}]]></c:codeExpression>                </c:EAN13>            </componentElement>[/code]

If I use jasperPrint.setProperty(JRPdfExporterParameter.PROPERTY_FORCE_SVG_SHAPES, "false") :

If I use jasperPrint.setProperty(JRPdfExporterParameter.PROPERTY_FORCE_SVG_SHAPES, "true") :

How can I remove this empty space at the top of the barecode ?
