SDL_MapRGB

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 returned +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).
