[Gambas-user] Image handling ...

[Gareth Bult]

What I'm doing is;

PRIVATE $pic as Picture

Every time an image comes in I call;

File.Save("/tmp/temp",buffer)
$pic = Picture.Load("/tmp/temp")
canvas.refresh

Where buffer comes in from the camera over a httpclient connection.
(and 'canvas' is my drawing area)

Then I have;

PUBLIC SUB canvas_Draw()

  draw.Picture($pic,0,0,320,240)

END

.. this works like a charm .. 
(I have buffer = FALSE by the way)

How does a DrawingArea work with a Picture object, such as one gets from
a VideoDevice?

Thanks,

Bob
