java svg 生成图片 报错

主要代码如下：
try {
            byte[] bytes = svgCode.getBytes("utf-8");
            JPEGTranscoder t = new JPEGTranscoder();
            TranscoderInput input = new TranscoderInput(new ByteArrayInputStream(bytes));
            TranscoderOutput output = new TranscoderOutput(outputStream);
            
            t.transcode(input, output);
            outputStream.flush();
        } finally {
            if (outputStream != null) {
                try {
                    outputStream.close();
                } catch (IOException e) {
                    e.printStackTrace();
                }
            }
        }
报错地方：t.transcode(input, output);
