How to make runtime instance of TUniCanvas transparent?

[Samsung]

Hi!

For the showing dynamic data i create runtime instance of TUniCanvas and it image change periodicaly via BitmapCanvas.

Once created, it is transparent. But as soon as I draw something (even a simple line or change the color of one pixel) - transparency is lost

Can I make it transparent permanently?

Thanks!

Everything in picture 3 what is not in picture 2 should be in the uniCanvas .. 

The transparent uniCanvas should lay over the unidbgrid ..
