void DrawIMG	(	SDL_Surface *	screen,
		SDL_Surface *	img,
		int	x,
		int	y,
		int	flags
	)

Draw an image on a surface.

void DrawLine	(	SDL_Surface *	screen,
		SDLEXT_Coord *	coord1,
		SDLEXT_Coord *	coord2,
		Uint8	r,
		Uint8	g,
		Uint8	b
	)

Draw a line on a surface.

Parameters:

screen	The target surface to draw the line on.
coord1	Coordinate one (from).
coord2	Coordinate two (to).

void DrawPixel	(	SDL_Surface *	screen,
		int	x,
		int	y,
		Uint8	r,
		Uint8	g,
		Uint8	b
	)

Draw a pixel on a surface.

void DrawRect	(	SDL_Surface *	screen,
		SDL_Rect *	rect,
		Uint8	r,
		Uint8	g,
		Uint8	b
	)

Draw a rectangle on a surface.

Uint32 GetPixel	(	SDL_Surface *	screen,
		int	x,
		int	y
	)

Retrieve pixel data from a surface.

SDL_Surface* Image_Load	(	const char *	filename,
		bool	bOptimize
	)

Loads an image and optionally optimizes the loaded surface.

void Slock ( SDL_Surface * screen )

Locks a surface.

void Sulock ( SDL_Surface * screen )

Unlocks a surface.

SDL_Surface* Surface_Optimize ( SDL_Surface * pSurface )

Optimizes a surface for faster blitting.

Remarks:: Returns a surface in case of success. Returns 0 in case of failure.

After executing this function, the specified surface for 'pSurface' won't be useable anymore (it's freed). Please replace the specified surface immediately with the return value of this function.
