NAME¶
SDL_GetRGBA - Get RGBA values from a pixel in the specified format.
SYNOPSIS¶
#include "SDL3/SDL.h"
void SDL_GetRGBA(Uint32 pixel, const SDL_PixelFormat * format, Uint8 * r, Uint8 * g, Uint8 * b, Uint8 * a);
DESCRIPTION¶
This function uses the entire 8-bit [0..255] range when converting color components from pixel formats with less than 8-bits per RGB component (e.g., a completely white pixel in 16-bit RGB565 format would return [0xff, 0xff, 0xff] not [0xf8, 0xfc, 0xf8]).
If the surface has no alpha component, the alpha will be returned as 0xff (100% opaque).
FUNCTION PARAMETERS¶
AVAILABILITY¶
This function is available since SDL 3.0.0.
