Hi,
No, does not work for me:

Exception occurs on
jtrans.transcode(input, output);
I've never seen an IncompatibleClassChangeError.
Is Batik and the Sun implemention different? (different versions?)
In the batik sources, I cant find
"com.sun.image.codec.jpeg.JPEGImageEncoder" class or interface.
The JPEGTranscoder is located in the package
"org.apache.batik.transcoder.image".
What version of JPEGImageEncoder do I need?
Do I need the Java Image I/O?
Do I need to download it?
Is there another way for saving a DOM (SVGDocument) to a JPEG?
-----------
JDK 1.5 for Macosx
batik-1.7
thx.
Simon.

Betreff: Document saved as JPEG - getting IncompatibleClassChangeError
Hi,
Saving as SVG or PNG works fine.
But I am getting error when doing this:
I use this piece of code to save a document as a JPEG:
<code>
public void saveAsJPEG(File file) throws IOException,
TranscoderException {
JPEGTranscoder t = new JPEGTranscoder();
t.addTranscodingHint(JPEGTranscoder.KEY_QUALITY, new Float(1.0));
TranscoderInput input = new TranscoderInput(document);
OutputStream ostream = new FileOutputStream(file);
TranscoderOutput output = new TranscoderOutput(ostream);
t.addTranscodingHint(JPEGTranscoder.KEY_WIDTH, new Float(100));
t.addTranscodingHint(JPEGTranscoder.KEY_HEIGHT, new Float(100));
t.transcode(input, output);
ostream.flush();
ostream.close();
}
</code>

Has anybody had similar problems?
Where is "com.sun.image.codec.jpeg.JPEGImageEncoder" located? Inside
the batik.jar? Or is it a problem of my com.sun.image.codec.jpeg
package?
batik jar: batik-1.7.jar
I'am using JDK 1.5 on MacOsX 10.5.6.
Developing with Eclipse 3.4
Thx
Simon
