以下是您要求的代码翻译部分：

  1. try {
  2.     PNGTranscoder coder = new PNGTranscoder();
  3.     StringReader reader = new StringReader(getSVG());
  4.     TranscoderInput input = new TranscoderInput(reader);
  5.     FileOutputStream outputStream = new FileOutputStream("tmp/tmp.png");
  6.     TranscoderOutput transcoderOutput = new TranscoderOutput(outputStream);
  7.     try {
  8.         coder.transcode(input, transcoderOutput);
  9.     } finally {
  10.         reader.close();
  11.         outputStream.close();
  12.     }
  13. } catch (Exception e) {
  14.     ErrorHandler.getInstance().handle(e);
  15. }

英文:

I want to generate a png from a svg string with this code:

  1.                     try {
  2.                         PNGTranscoder coder = new PNGTranscoder();
  3.                         StringReader reader = new StringReader(getSVG());
  4.                         TranscoderInput input = new TranscoderInput(reader);
  5.                         FileOutputStream outputStream = new FileOutputStream("tmp/tmp.png");
  6.                         TranscoderOutput transcoderOutput = new TranscoderOutput(outputStream);
  7.                         try{
  8.                             coder.transcode(input, transcoderOutput);
  9.                         }finally{
  10.                             reader.close();
  11.                             outputStream.close();
  12.                         }
  13.                     } catch (Exception e) {
  14.                         ErrorHandler.getInstance().handle(e);
  15.                     }

But if i run the code, i get an exception because an uri cant be opend because it is corrup or unsupported:

  1. org.apache.batik.bridge.BridgeException: null:0
  2. The URI "https://cdn.discordapp.com/avatars/xxx/xxx.png"
  3. on element <image> can't be opened because:
  4. JDK URL is corrupt or unsupported variant
  5. 	at org.apache.batik.bridge.UserAgentAdapter.getBrokenLinkDocument(UserAgentAdapter.java:449)
  6. 	at org.apache.batik.bridge.SVGImageElementBridge.createRasterImageNode(SVGImageElementBridge.java:604)
  7. 	at org.apache.batik.bridge.SVGImageElementBridge.createImageGraphicsNode(SVGImageElementBridge.java:327)
  8. 	at org.apache.batik.bridge.SVGImageElementBridge.buildImageGraphicsNode(SVGImageElementBridge.java:177)
  9. 	at org.apache.batik.bridge.SVGImageElementBridge.createGraphicsNode(SVGImageElementBridge.java:119)
  10. [...]

While converting this svg: https://hastebin.com/mamudofira.xml

The image url is replaced for privacy but its working!

得分: 0

我通过首先将图像下载为Base64字符串，然后将其设置为SVG中的xlink:href，自行解决了这个问题。

英文:

I fixed it myself by first downloading the image as base64 string and then setting it as xlink:href in the svg.
