Transcoder API example
I am trying the first Transcoder API example with the following code:
import java.io.*;
import org.apache.batik.transcoder.image.JPEGTranscoder;
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();
// Set the transcoding hints.
t.addTranscodingHint(JPEGTranscoder.KEY_QUALITY,
new Float(.8));
// Create the transcoder input.
String svgURI = new File(args[0]).toURL().toString();
System.out.println("svgURI = " + svgURI);
TranscoderInput input = new TranscoderInput(svgURI);
// Create the transcoder output.
OutputStream ostream = new FileOutputStream("out.jpg");
TranscoderOutput output = new TranscoderOutput(ostream);
// Save the image.
t.transcode(input, output);
// Flush and close the stream.
ostream.flush();
ostream.close();
System.exit(0);
}
}
But I got the following error:
200 rlaw ~/downloads/batik-1.6/test > java SaveAsJPEG batikYin.svg
svgURI = file:/home/rlaw/downloads/batik-1.6/test/batikYin.svg
Exception in thread "main" java.lang.NullPointerException

batikYin.svg is from xml-batik/samples and is in the same directory as SaveAsJPEG.class. What could I be missing?
Ray,

Hi Ray,
It seems your environment may not have resources directory or
XMLResourceDescriptor.properties file under util directory.
Thanks,
Selva
