[Pythoncard-users] tips on reducing flicker?

[Alec B. <wry...@gm...>]

I have a PythonCard app that creates collages from a directory of pictures.
It makes a show of the process, displaying each picture as its added, about
two per second, full screen.

My problem is that every time a new picture is added, the whole screen
flickers. This isn't really that surprising consdiering the way I'm doing
it: the new image gets pasted onto a fresh canvas and then the old image
(the previous frame) gets swapped out for the new image (the current frame).
When this image swap happens the screen flickers a little bit, but since it
happens twice per second its very distracting.

Can anyone think of a way to reduce this flicker?

In wx I could set something like
self.SetBackgroundStyle(wx.BG_STYLE_CUSTOM), but not in PythonCard as far as
I can tell?

Or some other way to do this?

Thanks for any tips.
