SDL_BITSPERPIXEL - A macro to determine an SDL_PixelFormat

Defined in SDL3/SDL_pixels.h

#include "SDL3/SDL.h"

#define SDL_BITSPERPIXEL(format) .BI (SDL_ISPIXELFORMAT_FOURCC(format) ? 0 : (((format) >> 8) & 0xFF))

Note that this macro double-evaluates its parameter, so do not use expressions with side-effects here.

FourCC formats will report zero here, as it rarely makes sense to measure them per-pixel.

Returns the bits-per-pixel of format .

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
