RE: svgz to jpeg ?
I think you'll have to write your own GZipGenerator or possibly a GZipSource? You are right that the gzipped svg document is not a ZIP archive (it doesn't include a table of contents or anything - it's just a single BLOB). On the bright side, gzip is trivial to use in Java, so writing your own shouldn't be hard.

I guess this is because there is no physical file to extract i.e jar:http//localhost/xyz.svg!??? Even Winzip will not open it. I haven't tried the zip generator yet because I haven't found any documentation, and someone has borrowed my Cocoon book !!

Re: svgz to jpeg ?
Just use the svg2jpg serializer. That's it. Regards, Upayavira On 27 Jun 2003 at 22:26, rob wrote: Hi, does anyone know if it is possible to serialize a compressed svg file (svgz) to jpeg ?

Re: svgz to jpeg ?
Thanks for you reply, but how do I generate the source ? The file generator only seems to accept uncompressed svg. When I use a compressed svg as the source I get the following error message : Original Exception: org.xml.sax.SAXParseException: Content is not allowed in prolog. at org.apache.xerces.util.ErrorHandlerWrapper.createSAXParseException(Unknown Source) at org.apache.xerces.util.ErrorHandlerWrapper.fatalError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLErrorReporter.reportError(Unknown Source) at org.apache.xerces.impl.XMLScanner.reportFatalError(Unknown Source) at org.apache.xerces.impl.XMLDocumentScannerImpl$PrologDispatcher.dispatch(Unknown Source) at org.apache.xerces.impl.XMLDocumentFragmentScannerImpl.scanDocument(Unknown Source) at org.apache.xerces.impl.XMLVersionDetector.scanDocument(Unknown Source) at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source) at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source) at org.apache.xerces.parsers.XMLParser.parse(Unknown Source) at org.apache.xerces.parsers.AbstractSAXParser.parse(Unknown Source) at org.apache.excalibur.xml.impl.JaxpParser.parse(JaxpParser.java:318) at org.apache.excalibur.xml.impl.JaxpParser.parse(JaxpParser.java:337) at org.apache.cocoon.components.source.SourceUtil.parse(SourceUtil.java:198) at org.apache.cocoon.generation.FileGenerator.generate(FileGenerator.java:140) at org.apache.cocoon.components.pipeline.impl.AbstractCachingProcessingPipeline.processXMLPipeline(AbstractCachingProcessingPipeline.java:277) at org.apache.cocoon.components.pipeline.AbstractProcessingPipeline.process(AbstractProcessingPipeline.java:489) at org.apache.cocoon.components.treeprocessor.sitemap.SerializeNode.invoke(SerializeNode.java:150) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:84) at org.apache.cocoon.components.treeprocessor.sitemap.PreparableMatchNode.invoke(PreparableMatchNode.java:164) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:108) at org.apache.cocoon.components.treeprocessor.sitemap.PipelineNode.invoke(PipelineNode.java:162) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:108) at org.apache.cocoon.components.treeprocessor.sitemap.PipelinesNode.invoke(PipelinesNode.java:162) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:325) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:307) at org.apache.cocoon.components.treeprocessor.sitemap.MountNode.invoke(MountNode.java:133) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:84) at org.apache.cocoon.components.treeprocessor.sitemap.PreparableMatchNode.invoke(PreparableMatchNode.java:164) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:108) at org.apache.cocoon.components.treeprocessor.sitemap.PipelineNode.invoke(PipelineNode.java:162) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:108) at org.apache.cocoon.components.treeprocessor.sitemap.PipelinesNode.invoke(PipelinesNode.java:162) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:325) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:307) at org.apache.cocoon.components.treeprocessor.sitemap.MountNode.invoke(MountNode.java:133) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:84) at org.apache.cocoon.components.treeprocessor.sitemap.PreparableMatchNode.invoke(PreparableMatchNode.java:164) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:108) at org.apache.cocoon.components.treeprocessor.sitemap.PipelineNode.invoke(PipelineNode.java:162) at org.apache.cocoon.components.treeprocessor.AbstractParentProcessingNode.invokeNodes(AbstractParentProcessingNode.java:108) at org.apache.cocoon.components.treeprocessor.sitemap.PipelinesNode.invoke(PipelinesNode.java:162) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:325) at org.apache.cocoon.components.treeprocessor.TreeProcessor.process(TreeProcessor.java:307) at org.apache.cocoon.Cocoon.process(Cocoon.java:628) at org.apache.cocoon.servlet.CocoonServlet.service(CocoonServlet.java:1139) at javax.servlet.http.HttpServlet.service(HttpServlet.java:853) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:247) at
