RE: SourceWritingTransformer to save jpeg/png to filesystem

[jim basilakis <ji...@ee.unsw.edu.au>]

Thanks for your reply.

I have tried replacing the serializer value from 'xml' to 'svg2png' and it
gave an error saying it not able to do this. I will try and look at the
source code and see what I can do save an image on the filesystem. If I get
the answer I will let you know.

Thanks again,
Jim

You can certainly set the serializer. The javadocs say:

Definition:

 <map:transformer     name="tofile"
src="org.apache.cocoon.transformation.SourceWritingTransformer">
   <!-- 'xml' is the default Serializer (if your Source needs one, like for
instance FileSource) -->
   <map:parameter name="serializer" value="xml"/>
 </map:transformer/>


Invocation:

 <map:transform type="tofile">
   <map:parameter name="serializer" value="xml"/>   <!-- you can optionally
override the serializer here -->
 </map:transform>

And you replace the xml with svg2png.

[Never tried it though...]
