我从 apache png 转码器得到一个 org.apache.batik.bridge.BridgeException

I get an org.apache.batik.bridge.BridgeException from apache png transcoder

我想使用以下代码从 svg 字符串生成 png:

                    try {
                        PNGTranscoder coder = new PNGTranscoder();
                        StringReader reader = new StringReader(getSVG());
                        TranscoderInput input = new TranscoderInput(reader);
                        FileOutputStream outputStream = new FileOutputStream("tmp/tmp.png");
                        TranscoderOutput transcoderOutput = new TranscoderOutput(outputStream);
                        try{
                            coder.transcode(input, transcoderOutput);
                        }finally{
                            reader.close();
                            outputStream.close();
                        }
                    } catch (Exception e) {
                        ErrorHandler.getInstance().handle(e);
                    }

但是如果我 运行 代码,我会得到一个异常,因为 uri 因损坏或不受支持而无法打开:

org.apache.batik.bridge.BridgeException: null:0
The URI "https://cdn.discordapp.com/avatars/xxx/xxx.png"
on element <image> can't be opened because:
JDK URL is corrupt or unsupported variant

在转换此 svg 时:https://hastebin.com/mamudofira.xml

图像 url 已为保护隐私而被替换,但它有效!

我自己修复了这个问题,首先将图像下载为 base64 字符串,然后在 svg 中将其设置为 xlink:href
