Detailed Description

CVideoSystem is an abstract interface to a video subsystem. It also serves as an abstract factory for implementation-specific objects, such as bitmap surfaces. This is a singleton class managed by a CSingletonManager.

Member Function Documentation

virtual CScreen& CVideoSystem::get_screen (   )  [pure virtual]

Return a CScreen surface that represents the video screen of the surface. See the CScreen object for more information on the nature of the screen as a singleton. Implemented in SDLDriver::CVideoSystemSDL.

virtual uint32 CVideoSystem::make_color (  uint8  r, uint8  g, uint8  b )  [protected, pure virtual]

Return the 32-bit integer representing the given color with (red, green, blue). It should be in the video system's architecture-dependent pixel format. Implemented in SDLDriver::CVideoSystemSDL.

virtual CSurfaceImpl* CVideoSystem::make_csurface_impl (  const char *  filename  )  [protected, pure virtual]

Return a bitmap surface that represents the given image file name (usually a Windows BMP file). Note that the pixel format used will be the image file's, NOT the screen's. Implemented in SDLDriver::CVideoSystemSDL.

virtual CSurfaceImpl* CVideoSystem::make_csurface_impl (  int  w, int  h )  [protected, pure virtual]

Create a CSurfaceImpl with the given width and height. The screen's pixel format is used. Implemented in SDLDriver::CVideoSystemSDL.
