Set up a video mode with the specified width, height and bits-per-pixel.
If bpp is 0, it is treated as the +current display bits per pixel.
The flags parameter is the same as the flags field of the SDL_Surface structure. OR'd combinations of the following values are valid.
| SDL_SWSURFACE | Create the video surface in system memory |
| SDL_HWSURFACE | Create the video surface in video memory |
| SDL_ASYNCBLIT | Enables the use of asynchronous updates of the display surface. This will +usually slow down blitting on single CPU machines, but may provide a speed +increase on SMP systems. |
| SDL_ANYFORMAT | Normally, if a video surface of the requested bits-per-pixel (bpp) is not available, SDL will emulate one with a shadow surface. Passing SDL_ANYFORMAT prevents this and causes SDL to use the video surface, regardless of its pixel depth. |
| SDL_HWPALETTE | Give SDL exclusive palette access. Without this flag you may not always get the the colors you request with SDL_SetColors or SDL_SetPalette. |
| SDL_DOUBLEBUF | Enable hardware double buffering; only valid with SDL_HWSURFACE. Calling +SDL_Flip will flip the +buffers and update the screen. All drawing will take place on the surface +that is not displayed at the moment. If double buffering could not be enabled +then SDL_Flip will just perform a +SDL_UpdateRect +on the entire screen. |
| SDL_FULLSCREEN | SDL will attempt to use a fullscreen mode. If a hardware resolution change is +not possible (for whatever reason), the next higher resolution will be used and +the display window centered on a black background. |
| SDL_OPENGL | Create an OpenGL rendering context. You should have previously set OpenGL video attributes with SDL_GL_SetAttribute. |
| SDL_OPENGLBLIT | Create an OpenGL rendering context, like above, but allow normal blitting +operations. The screen (2D) surface may have an alpha channel, and +SDL_UpdateRects +must be used for updating changes to the screen surface. NOTE: This option +is kept for compatibility only, and is not recommended for +new code. |
| SDL_RESIZABLE | Create a resizable window. When the window is resized by the user a SDL_VIDEORESIZE event is generated and SDL_SetVideoMode can be called again with the new size. |
| SDL_NOFRAME | If possible, SDL_NOFRAME causes SDL to create a window with no title bar or frame decoration. Fullscreen modes automatically have this flag set. |
Note: Whatever flags SDL_SetVideoMode could satisfy are set in the flags member of the returned surface.
Note: The bpp parameter is the number of bits per pixel, +so a bpp of 24 uses the packed representation of +3 bytes/pixel. For the more common 4 bytes/pixel mode, use a +bpp of 32. Somewhat oddly, both 15 and 16 will +request a 2 bytes/pixel mode, but different pixel formats.
