Uint8 Graphics::calcBlueComp (  SDL_PixelFormat *    format, Uint32    pixel )

Definition at line 297 of file draw.cpp.

Uint8 Graphics::calcGreenComp (  SDL_PixelFormat *    format, Uint32    pixel )

Definition at line 290 of file draw.cpp.

Uint8 Graphics::calcRedComp (  SDL_PixelFormat *    format, Uint32    pixel )

Definition at line 283 of file draw.cpp.

Graphics::AbstractImage * Graphics::dynGenerateImage (  const string &    filename )

Reads a filename, and creates an instance of the appriopriate AbstractImage subclass based on the filename's extension. List of extension/class pairs thus far .bmp - SingleFrameImage .ani - AnimatedImage Parameters: filename  name of file Exceptions: exception  thrown when the extension is not in the above list Returns: dynically allocated AbstractImage* to appriopriate subclass Definition at line 196 of file draw.cpp.

Uint32 Graphics::getpixel (  SDL_Surface *    surface, int    x, int    y )

NOTE: The surface must be locked before calling this! Returns: the pixel value at (x, y) Definition at line 247 of file draw.cpp.

Uint32 Graphics::makeTopLeftPixelTrans (  SDL_Surface *    lpSurface )

Definition at line 274 of file draw.cpp.

void Graphics::putpixel (  SDL_Surface *    surface, int    x, int    y, Uint32    pixel )

NOTE: The surface must be locked before calling this! Set the pixel at (x, y) to the given value Definition at line 214 of file draw.cpp.
