Hi Thor,

here is a little example, which shows how to freeze a SCUserView:

That example makes me realise that there should be a clear method, to wipe

out everything drawn.

Note that clearOnRefresh_(false) works only with relativeOrigin_(true).

Hi Jan

thanks for this!! Exactly what I needed. But I desperately also need the clear

Can you easily add a .clear?

Check the following:

(it draws on top of the other drawing. If I then set clearOnRefresh to true, it

removes the drawing when the window is refreshed)
