SVG as background
An SVG (as a Nuclos String (Large Object)) can be rendered as a background image. Pure SVG/XML only – no embedded raster graphics!
| Codeblock |
|---|
|
<background>
<band height="845">
<image>
<reportElement mode="Transparent" x="1" y="0" width="530" height="845"/>
<imageExpression class="net.sf.jasperreports.engine.JRRenderable">net.sf.jasperreports.renderers.BatikRenderer.getInstance($F{teststring}.getBytes())</imageExpression>
</image>
</band>
</background> |
| Tipp |

|
For transparency replace in SQL: replace(text, "opacity:", "fill-opacity:"). |
