Hi Luca,
I'm woking for an animation with wxPython. I need to move an image
and zoom it. I've tried with DCs, using double buffer method to reduce
the flicking. So I've tested the animation on 2 computers: they have
almost the same features, (the bigger difference is on the graphical
board: computer1 mounts geForce, computer2 Ati)but on computer1 the
animation works slowly, and the process needs the 100% of CPU. Computer2
takes this animation more easy and needs only 30-35% of CPU and it
results more fluid and nice to see. I'll need to run this animation on a
low performance computers...maybe I'm doing something wrong...Any ideas?
Ciao Andrea,
Two or three of them:
1) Try FloatCanvas: wx.lib.floatcanvas
Do you think this could be work better?
2) Are you using wx.BufferedPaintDC() together with an empty
wx.EVT_ERASE_BACKGROUND?
Yes, I'm using BufferedDC but not wx.EVT_ERASE_BACKGROUND.
3) If you post some code, I am sure some DC guru can help you.
I simply use a wx.Bitmap and a wxDC.SetUserScale for the zoom... 30 or 40 code lines..
Andrea.
