I am trying to do something similar as described below but using the
PDFTranscoder. I modified the code as follows:
import java.io.IOException;
import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;
import org.apache.fop.svg.PDFTranscoder;
import org.apache.batik.transcoder.TranscoderException;
import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
public class TranscodingServlet extends HttpServlet {
public void doPost(HttpServletRequest request,
HttpServletResponse response)
throws IOException, ServletException {
response.setContentType("application/pdf");
PDFTranscoder t = new PDFTranscoder();
/*t.addTranscodingHint(ImageTranscoder.KEY_WIDTH, new
Float(1056));*/
/*t.addTranscodingHint(ImageTranscoder.KEY_HEIGHT, new
Float(816));*/
TranscoderInput input = new TranscoderInput(request);
TranscoderOutput output = new
TranscoderOutput(response.getOutputStream());
try {
t.transcode(input, output);
} catch (TranscoderException ex) {
throw new ServletException(ex);
}
}
}
I am trying to compile this with:
javac -classpath servlet-api.jar;batik-transcoder.jar;pdf-transcoder.jar
TranscodingServlet.java
The three .jar files are in the same directory as
TranscodingServlet.java. servlet-api.jar is from Apache-tomcat 6.0 and
the others are from Batik 1.7. I think my JAVA is setup OK - I can
compile all of Batik from source. The error I get is:
TranscodingServlet.java:24 cannot find symbol
symbol : construction
TranscoderInput(javax.servlet.htto.HttpServletRequest)
location : class org.apache.batik.transcoder.TranscoderInput
TranscoderInput input = new TranscoderInput(request);
The error ^ points to new in the last line. Can anyone help on this? I
am afraid I am lost when it comes to JAVA.
Thanks

OK, I know a lot of people had the same problem, but reading through
forums
for 2 days now didn't help me at all.
I have a basic website with a svg embedded. The SVG has some JS in
there for
the user to change the svg. I would love to have a button to export
the svg
to a JPEG. I already downloaded the batik package and put it on the
server, I just
can't find the right way to call the rasterizer.
If you can run Java servlets on your server, then you can write a simple
servlet that will do the rasterising. Here is a simple example:
http://mcc.id.au/2007/09/batik-course/code/transcoding-servlet/
The actual code is in WEB-INF/classes/TranscodingServlet.java. That
example servlet causes a URI with the following form to return a PNG:
http://server/transcoding-servlet/transcode?uri=<uri-of-SVG-document>
&width=<width-of-output-PNG>&height=<height-of-output-PNG>
