Function Documentation

Surface_to_bytefield()

byte * Surface_to_bytefield	(	SDL_Surface *	source,
		byte *	dest
	)

Converts a SDL_Surface (indexed colors or RGB) into an array of bytes (indexed colors).

If dest is NULL, it's allocated by malloc(). Otherwise, be sure to pass a buffer of the right dimensions.

References NULL.

Color_to_SDL_color()

SDL_Color Color_to_SDL_color

(

byte

index

)

Gets the RGB 24-bit color currently associated with a palette index.

References Main, and T_Document::palette.

Get_SDL_pixel_8()

byte Get_SDL_pixel_8	(	const SDL_Surface *	bmp,
		int	x,
		int	y
	)

Reads a pixel in a 8-bit SDL surface.

Get_SDL_pixel_hicolor()

dword Get_SDL_pixel_hicolor	(	const SDL_Surface *	bmp,
		int	x,
		int	y
	)

Reads a pixel in a multi-byte SDL surface.

Set_SDL_pixel_8()

void Set_SDL_pixel_8	(	SDL_Surface *	bmp,
		int	x,
		int	y,
		byte	color
	)

Writes a pixel in a 8-bit SDL surface.

Get_SDL_Palette()

void Get_SDL_Palette	(	const SDL_Palette *	sdl_palette,
		T_Palette	palette
	)

Convert a SDL Palette to a grafx2 palette.
