| 48 | <h2><center>Alpha Drawing</center></h2> | |
| 49 | ||
| 50 | The wx.DC on Mac now supports alpha transparent drawing using pens and | |
| 51 | brushes. This is accomplished by enabling the wx.Colour class to have | |
| 52 | a fourth component for the alpha value, where 0 is fully transparent, | |
| 53 | and 255 is fully opaque. | |

| 56 | other platforms. | |
