Hello Vincent,
Thank you for your reply. I wrote this class which abuses the spirit of
the transcoding api a bit but does what I need
import java.awt.image.BufferedImage;
import org.apache.batik.transcoder.TranscoderOutput;
import org.apache.batik.transcoder.TranscoderException;
import org.apache.batik.transcoder.image.ImageTranscoder;
class BufferedImageTranscoder
extends ImageTranscoder
{
private BufferedImage image;
public BufferedImage createImage(int width, int height)
{
return new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
}
public void writeImage(BufferedImage image, TranscoderOutput output)
throws TranscoderException
{
// ignore output parameter
this.image = image;
}
public BufferedImage getImage()
{
return image;
}
}
