Unfortunately on Linux I'm getting a segfault with that test on the last line
in the
following block:
53 print "Bitmap depth is:", B.GetDepth()
54 pdata = wx.AlphaPixelData(B)
55 pacc = pdata.GetPixels()
56 pacc.MoveTo(pdata, i,j)
57 outColor = pacc.Get()[:3]
It does seem to run fine on Mac, though.
