Hello,
i tray to simulate an analogic clock. (I found a nice example in and oreilly book)
I have do some tray with Tkinter, but i will use a nicer image (with a GIF image) ...
i make a tray with PIL, but the rotate function give strange image !! (with black corners)
than i will tray with wx ... but i don't no how to superimpose 2 GIF image (with some transparency part, and where one image have be rotated) ;-((
I make many google search but i don't found the informations I'm looking for. I just found some ideas, but I'm really not sure of the better way to go on :
- use the dc.DrawBitmap to draw the image on a memoryDC, when done drawing blit the result to the paintDC.
- use PNGs rather than GIFS, they support alpha
- use something like img.SetAlpha(i,j, 255) for i,j in the pixels outside the zone of interest to get rid of the black corners (img is a wx.Image)
- take a look at Andrea's SpeedMeter http://xoomer.virgilio.it/infinity77/eng/freeware.html#speedmeter

How about:
wx.lib.analogclock
In any case, I'm a little confused as to why you need to superimpose two GIFs? I can see you might want to use an Image as the background, but then you can just draw the parts that move (the hands) in top of the Image with a wx.MemoryDC.
