| |
|
24 |
This function takes a surface and copies it to a new surface |
| |
|
25 |
of the pixel format and colors of the video framebuffer plus |
| |
|
26 |
an alpha channel, suitable for fast blitting onto the |
| |
|
27 |
display surface. It calls |
| |
|
28 |
''SDL_!ConvertSurface'' |
| |
|
29 |
|
| |
|
30 |
|
| |
|
31 |
If you want to take advantage of hardware colorkey or alpha |
| |
|
32 |
blit acceleration, you should set the colorkey and alpha |
| |
|
33 |
value before calling this function. |
| |
|

If the conversion fails or runs out of memory, it returns |
| |
|
38 |
__NULL__ |
