wxPython's wx.RegionFromBitmap() wxPerl equalevant

[Justin zhang]

Hi All,
  Anyone know what's the wxPerl equalevant for wxPython's
wx.RegionFromBitmap()? This method creates a Wx::Region instance from a
bitmap. I followed the example code in the book *wxPython in action *which
says this is a global method. So I tried:

Wx::RegionFromBitmap()

However, I got error like:

Error while autoloading 'Wx::RegionFromBitmap' at ShapedWin1.pl line 63

Any idea?

Thank you very much!
