HarmonyOS svg数据类型：uint8array ，image组件怎么显示

1. 可以先通过createPixelMap方法创建一个PixelMap对象，再将创建好的PixelMap对象通过RPC进行传输。
2. uint8array 转为base64 可解决。

Uint8Array 转base64 请参考以下代码demo案例

  // ss为base64的String
  let ss = "2N+ZMvs8Dn4HVylFmddFa4COJnkoz7PkgPsR7iGDgnU53S5TW5eMen7BIqc59bXt7kEDbqNUe+PQUmbRMoU9gJ9hcv79QzN0iQJPux5q1rM="
  // 生成 util base64Help
  let base64Helper = new util.Base64Helper();
  // 对base64的string 解码为 Uint8Array
  let keySS = base64Helper.decodeSync(ss);
  console.log("keySS : "+keySS.toString());
  // 对Uint8Array 转码为base64 的String
  let keyNN = base64Helper.encodeToStringSync(keySS)
  console.log("keyNN : "+keyNN.toString());

输出如下

// Uint8Array

// base64
