SDL_MapRGB(3) SDL API Reference SDL_MapRGB(3)
NAME
SDL_MapRGB - Map a RGB color value to a pixel format.
SYNOPSIS
#include "SDL.h"
Uint32 SDL_MapRGB(SDL_PixelFormat *fmt, Uint8 r, Uint8 g, Uint8 b);
DESCRIPTION
Maps the RGB color value to the specified pixel format and returns the
pixel value as a 32-bit int.
If the format has a palette (8-bit) the index of the closest matching
color in the palette will be returned.
If the specified pixel format has an alpha component it will be re-
turned as all 1 bits (fully opaque).
RETURN VALUE
A pixel value best approximating the given RGB color value for a given
pixel format. If the pixel format bpp (color depth) is less than 32-bpp
then the unused upper bits of the return value can safely be ignored
(e.g., with a 16-bpp format the return value can be assigned to a
Uint16, and similarly a Uint8 for an 8-bpp format).
