3 SDL_MapRGBA\- Map a RGBA color value to a pixel format\&.
8 \fBUint32 \fBSDL_MapRGBA\fP\fR(\fBSDL_PixelFormat *fmt, Uint8 r, Uint8 g, Uint8 b, Uint8 a\fR);
11 Maps the RGBA color value to the specified pixel format and returns the pixel value as a 32-bit int\&.
13 If the format has a palette (8-bit) the index of the closest matching color in the palette will be returned\&.
15 If the specified pixel format has no alpha component the alpha value will be ignored (as it will be in formats with a palette)\&.
18 A pixel value best approximating the given RGBA 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 \fBUint16\fP, and similarly a \fBUint8\fP for an 8-bpp format)\&.
