| 54 | <h2><center>Images with Alpha</center></h2> | |
| 55 | ||
| 8e43747f | 56 | wxMSW and wxMac now support alpha channels of supported image |
| 6a8fa617 | 57 | types, and will properly blend that channel when drawing a |
| 8a88769e RD |
58 | bitmap. It is not supported yet on wxGTK, (if you would like to |
| 59 | change that please submit a patch!) | |
| 60 | ||
| 803a0ba6 RD |
61 | <p>On wxGTK this demo turns the alpha channel into a 1-bit mask, so |
| 62 | yes, it looks like crap. Please help us fix it! | |
