Alpha Drawing

- -The wx.GCDC class is a class that implemented the wx.DC API using the -new wx.GraphicsContext class, and so it supports anti-aliased drawing -using pens and brushes, that can optionally also be drawn using an -alpha transparency. (On the Mac all the DC classes are using this new -implementation.) This is accomplished by enabling the wx.Colour class -to have a fourth component for the alpha value, where 0 is fully -transparent, and 255 is fully opaque. - - -""" - - - -if __name__ == '__main__': - import sys,os - import run - run.main(['', os.path.basename(sys.argv[0])] + sys.argv[1:]) -
