    I have double check with my data. Actually you don't need to convert it. What I realized is this portion "data:image/png;base64," or similar definition is not exist in my data. May be removing this part from data will solve your problem.

     

    =Replace(First(Fields!Delivery_Signature.Value, "DataSet"),"data:image/png;base64,","")

Hi ,

I removed the prefix from the data and in the database my particular column in LongBLOB data type and after  using the Replace DAX which one you gave this error is coming .

 

 

"The 'Value' expression for the image 'Image3' contains an error: [BC30455] Argument not specified for parameter 'Find' of 'Public Function Replace(Expression As String, Find As String, Replacement As String, [Start As Integer = 1], [Count As Integer = -1], [Compare As Microsoft.VisualBasic.CompareMethod = Microsoft.VisualBasic.CompareMethod.Binary]) As String'.
----------------------------
The definition of the report '' is invalid."

 

Can you please Help me in this 

 

Thanks & Regards
