[Gambas-user] Download JPG with HttpClient to memory

[EA7DFH]

Hi list

I am unable to download a JPG image from an IP Webcam and feed a
PictureBox, without creating a file-like object.

I'm using HttpClient to fetch the images asyncronously, but the buffer
at last is only a string representation of its binary data.

How do I convert this data into an actual image object for viewing in a
PictureBox or DrawingArea?

This is my code so far:


' Gambas class file

PUBLIC $http AS HttpClient
PRIVATE $pic AS String

PUBLIC SUB Form_Open()
  $http = NEW HttpClient AS "MyStream"
  $http.Async = TRUE
  $http.Timeout = 3
  $http.URL = "http://192.168.1.10:4500/axis-cgi/jpg" &
              "/image.cgi?resolution=320x240"
END

PUBLIC SUB Timer1_Timer()
  $http.Get
END

PUBLIC SUB MyStream_Read()
  DIM buffer AS String
  READ #LAST, buffer, Lof(LAST)
  $pic &= buffer
END

PUBLIC SUB MyStream_Finished()
  ' Here I want to feed the picturebox with the buffered JPG
  ' but $pic only contains a string repr of the binary image
   PictureBox1.Refresh
END

PUBLIC SUB btnStart_Click()
  Timer1.Start
END

PUBLIC SUB btnStop_Click()
  Timer1.Stop
END

PUBLIC SUB btnExit_Click()
  Timer1.Stop
  ME.Close
END

I'd like to avoid using a file, is it possible to do from RAM?
