Hi All,

Need help to convert PNG from staticmap Google to Base64 string

Sub Handle(req As ServletRequest, resp As ServletResponse)
   GetPNG (resp)

End Sub

Sub GetPNG(resp As ServletResponse)
   Dim job As HttpJob
   job.Initialize("",Me)
   job.Download2($"http://maps.googleapis.com/maps/api/staticmap"$ , Array As String("center","merlion+stue"  ,"size","640x480") )
   Wait For (job) JobDone(job As HttpJob)
   If job.Success Then
     resp.Write(  job.GetString  )  '<-- how to convert return to base64 string ??
   End If
   StopMessageLoop
End Sub

Thank You

Job.GetString cannot work if the returned value is a bitmap.

Dim su As StringUtils
Dim base64 As String = su.EncodeBase64(Bit.InputStreamToBytes(Job.GetInputStream))
