I am struggling to get Cocoon to generate even a simple SVG image
encoded as a .png file inside an HTML page.
I am working with a subsite in Cocon 2.0.
Here is the subsitemap entry:
<map:match pattern="test-graph">
<map:generate src="docs/testgraph.xml"/>
<map:transform src="styles/svg-graph-test.xsl"/>
<map:transform type="extractor"/>
<map:transform src="styles/fragment-extractor.xsl"/>
<map:serialize/>
</map:match>
<map:match pattern="svg-images/*.png">
<map:generate type="extractor" src="{1}"/>
<map:serialize type="svg2png"/>
</map:match>
<!-- there are obviously also all the necessary entries
in the map:serializer portion; as per the sample map
-->
A testgraph.xml file thus:
<?xml version="1.0" encoding="UTF-8"?>
<graph>
<circle/>
</graph>
with a svg-graph-test.xsl stylesheet thus:
<?xml version="1.0"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:xlink="http://www.w3.org/1999/xlink";
xmlns:svg="http://www.w3.org/2000/svg";>
<xsl:template match="/">
<html>
<head>
<title>SVG Test</title>
</head>
<body bgcolor="#ffffff">
<p align="center">Test inclusion of SVG into web page as HTML...</p>
<p align="center">
<svg:svg width="300" height="300">
<circle style="fill:blue;stroke:red;" cx="200" cy="200" r="100"/>
</svg:svg>
</p>
</body>
</html>
</xsl:template>
and a fragment (fragment-extractor.xsl) processor thus:
<?xml version="1.0"?>
<xsl:stylesheet
version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
xmlns:fe="http://apache.org/cocoon/fragmentextractor/2.0";>
<xsl:template match="//fe:fragment">
<img src="svg-images/{@fragment-id}.png" border="0"/>
</xsl:template>
<xsl:template match="@*|*|text()|processing-instruction()"
priority="-1">
<xsl:copy>
<xsl:apply-templates
select="@*|*|text()|processing-instruction()"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>
gives the following error in the log:
ERROR (2002-05-20) 15:34.32:867 [cocoon ]
(/cocoon/indicators/svg-images/4c9d70-edee15fcbf--8000.png)
HttpProcessor[8080][4]/SVGSerializer: SVGSerializer: Exception writing
image
org.apache.batik.transcoder.TranscoderException: null

Any help as to what is causing this would be appreciated
