sfsignature base 64 string cannot loaded

I'm using  latest Blazor  version 23.2.5 (community free edition due to revenue)

if you try to upload an base64 string the signature component doesn't show something below the code


FData = (byte[])row["FData"]; // load to an byte array from database

string xSignImg = Convert.ToBase64String(FData, 0, FData.Length);

xSignImg = string.Format("data:image/jpg;base64,{0}", xSignImg);

// or xSignImg = "data:image/jpg;base64,{0}" + xSignImg;


await Signature.LoadAsync(xSignImg, 400, 256);

The same problem also exists on image editor

The image is shown on a SfGrid column without any problem with the same code as below

on an Grid column template

var cntx = DocsFData as Code.LoginState.DocsFields;

string base64String = Convert.ToBase64String(cntx.FData, 0, cntx.FData.Length);

string imagesrc = "data:image/jpg;base64," + base64String;
