wx.AlphaPixelData() is failing on windows server 2003

Development matplotlib-devel

wx.AlphaPixelData() is failing on windows server 2003. The sample code is
given below.
The same is working fine on windows xp. what could be the reason?

import wx

class Size(wx.Frame):
    def __init__(self, parent, id, title):
        wx.Frame.__init__(self, parent, id, title, size=(250, 200))
        absFilename =
"C:\Python26\Lib\site-packages\win32\Demos\images\smiley.bmp"
        bmp = wx.Bitmap(absFilename, wx.BITMAP_TYPE_BMP)
        pixelData = wx.AlphaPixelData(bmp)

        if not pixelData:
            print "error"
        else:
            print "fine"

app = wx.App(False)
Size(None, -1, 'Test')
app.MainLoop()

Is this bug related to matplotlib? (i.e. does it happen only when matplotlib is imported?) If not, you may have more luck on the wxpython mailing list.

It looks like you've done a pure-wx test, so it is a wx issue.

If not, you may have more luck on the wxpython mailing list.

yup, that's the place for it -- I suspect that windows server 2003 is old enough that it may not have the newer alpha-supporting drawing stuff -- that may be a dll that you could add, though.

You'll get a better answer on the wxpython-users list.
