这真的很简单，只是不是很直观。
需要扩展ImageTranscoder。在createImage方法中，分配一个BufferedImage，将其缓存为成员变量，并返回它。writeImage方法为空。并且需要添加一个getter来检索BufferedImage。
它看起来像这样：

class MyTranscoder extends ImageTranscoder {
        private BufferedImage image = null;
        public BufferedImage createImage(int w, int h) {
            image = new BufferedImage(w, h, BufferedImage.TYPE_INT_ARGB);
            return image;
        }
        public void writeImage(BufferedImage img, TranscoderOutput out) {
        }
        public BufferedImage getImage() {
            return image;
        }
    }

现在，要创建一个图像，您需要创建一个代码转换器的示例，并通过设置TranscodingHints将所需的宽度和高度传递给它。最后，您需要从一个TranscoderInput代码转换为一个null目标。然后调用代码转换器上的getter来获取图像。
调用看起来像这样：

MyTranscoder transcoder = new MyTranscoder();
    TranscodingHints hints = new TranscodingHints();
    hints.put(ImageTranscoder.KEY_WIDTH, width);
    hints.put(ImageTranscoder.KEY_HEIGHT, height);
    transcoder.setTranscodingHints(hints);
    transcoder.transcode(new TranscoderInput(url), null);
    BufferedImage image = transcoder.getImage();

很简单，对吗？（是的，对。我只花了2个星期就想明白了。唉。）

我刚刚用蜡染-1.7遵循了德文郡的方法
然而，为了使它工作，我必须对hints对象进行以下添加：

MyTranscoder transcoder =new MyTranscoder()

DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
TranscodingHints hints = new TranscodingHints();
hints.put(ImageTranscoder.KEY_WIDTH, width); // e.g. width=new Float(300)
hints.put(ImageTranscoder.KEY_HEIGHT,height);// e.g. height=new Float(75)
hints.put(ImageTranscoder.KEY_DOM_IMPLEMENTATION, impl.getDOMImplementation());
hints.put(ImageTranscoder.KEY_DOCUMENT_ELEMENT_NAMESPACE_URI,SVGConstants.SVG_NAMESPACE_URI);
hints.put(ImageTranscoder.KEY_DOCUMENT_ELEMENT_NAMESPACE_URI,SVGConstants.SVG_NAMESPACE_URI);
hints.put(ImageTranscoder.KEY_DOCUMENT_ELEMENT, SVGConstants.SVG_SVG_TAG);
hints.put(ImageTranscoder.KEY_XML_PARSER_VALIDATING, false);

transcoder.setTranscodingHints(hints);
TranscoderInput ti=new TranscoderInput(uri)
transcoder.transcode(ti, null);
BufferedImage image = transcoder.getImage();

看起来batik的XMLAbstractTranscoder（http://svn.apache.org/repos/asf/xmlgraphics/batik/tags/batik-1_7/sources/org/apache/batik/transcoder/XMLAbstractTranscoder.java）版本1.7中有一些更新。

我尝试使用德文郡和John的建议，这几乎对我有效。我不得不做一些调整，如下所示，随时用途：

  public static BufferedImage loadSvg(URL url, float width) throws IOException {

    transcoder.setTranscodingHints(getHints(width));
    try {
      TranscoderInput input = new TranscoderInput(url.openStream());
      transcoder.transcode(input, null);
    } catch (TranscoderException e) {
      throw new IOException("Error parsing SVG file " + url, e);
    }
    BufferedImage image = transcoder.getImage();
    logger.atInfo().log("Read '%s' SVG image from disk requested with width=%.1f, sized as %dx%d pixels.",

  }

  private static class SvgTranscoder extends ImageTranscoder {

    private BufferedImage image = null;

    @Override
    public BufferedImage createImage(int width, int height) {
      image = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
      return image;
    }

    @Override
    public void writeImage(BufferedImage img, TranscoderOutput out) {}

    BufferedImage getImage() {
      return image;
    }
  }
}

要避免传递dom参数，请执行以下操作：transcoder.setTranscodingHints((Map<?, ?>) hints);
