Problem with generating PDF from Svg
Hi,
I have tried several methods of generating a PDF but I already end up with the following AbstractMethodError. Can anyone give me a hint as to what can be wrong? Thanks.
About to transcode 1 SVG file(s)
Converting test.svg to G:\Vss\Evaluation\batik\test.pdf ... java.lang.AbstractMethodError

Hi Vincent,
my batik and fop were only download last week so they should be
compatible with each other. As I read the ability to output to JPEG or PDF
is because of the transcoders, I changed the transcoder from JPEG to PDF to
find out if it is so.
import java.io.*;
import org.apache.batik.transcoder.image.JPEGTranscoder;
import org.apache.fop.svg.PDFTranscoder;
import org.apache.batik.transcoder.TranscoderInput;
import org.apache.batik.transcoder.TranscoderOutput;
public class SaveAsJpeg {
public static void main(String [] args) throws Exception {
// create a JPEG transcoder
//JPEGTranscoder t = new JPEGTranscoder();
PDFTranscoder t = new PDFTranscoder();
// set the transcoding hints
//t.addTranscodingHint(JPEGTranscoder.KEY_QUALITY, new Float(.8));
// create the transcoder input
String svgURI = new File("G://batik//test.svg").toURL().toString();
TranscoderInput input = new TranscoderInput(svgURI);
// create the transcoder output
OutputStream ostream = new FileOutputStream("G://batik//test.pdf");
TranscoderOutput output = new TranscoderOutput(ostream);
// save the image
t.transcode(input, output);
// flush and close the stream then exit
ostream.flush();
ostream.close();
System.exit(0);
}
}

Russ,
I suspect you are using an incompatible version of the PDF transcoder.
There has been an API change in Batik a couple months ago which
created an incompatibility. Did you try the most recent PDF transcoder?
