!!DESCRIPTION |
| |
|
22 |
|
| |
|
23 |
|
| |
|
24 |
Allocate an empty surface (must be called after |
| |
|
25 |
''SDL_!SetVideoMode'') |
| |
|
26 |
|
| |
|
27 |
|
| |
|
28 |
If __depth__ is 8 bits an empty palette is allocated for |
| |
|
29 |
the surface, otherwise a 'packed-pixel' |
| |
|
30 |
__SDL_!PixelFormat__ is created using the |
| |
|
31 |
__[[RGBA]mask__'s provided (see __SDL_!PixelFormat__). |
| |
|
32 |
The __flags__ specifies the type of surface that should |
| |
|
33 |
be created, it is an OR'd combination of the following |
| |
|
34 |
possible values. |
| |
|
35 |
|
| |
|
36 |
|
| |
|
37 |
__SDL_SWSURFACE__ |
| |
|
38 |
|
| |
|
39 |
|
| |
|
40 |
SDL will create the surface in system memory. This improves |
| |
|
41 |
the performance of pixel level access, however you may not |
| |
|
42 |
be able to take advantage of some types of hardware |
| |
|
43 |
blitting. |
| |
|
44 |
|
| |
|
45 |
|
| |
|
46 |
__SDL_HWSURFACE__ |
| |
|
47 |
|
| |
|
48 |
|
| |
|
49 |
SDL will attempt to create the surface in video memory. This |
| |
|
50 |
will allow SDL to take advantage of Video- |
| |
|
51 |
|
| |
|
52 |
|
| |
|
53 |
__SDL_SRCCOLORKEY__ |
| |
|
54 |
|
| |
|
55 |
|
| |
|
56 |
With this flag SDL will attempt to find the best location |
| |
|
57 |
for this surface, either in system memory or video memory, |
| |
|
58 |
to obtain hardware colorkey blitting support. |
| |
|
59 |
|
| |
|
60 |
|
| |
|
61 |
__SDL_SRCALPHA__ With this flag SDL will attempt to find |
| |
|
62 |
the best location for this surface, either in system memory |
| |
|
63 |
or video memory, to obtain hardware alpha |
| |
|
64 |
support |
