SDL_ISPIXELFORMAT_FOURCC - A macro to determine if an
SDL_PixelFormat
is a "FourCC" format.
Defined in SDL3/SDL_pixels.h
#include "SDL3/SDL.h"
#define SDL_ISPIXELFORMAT_FOURCC(format) /* The flag is set to 1 because 0x1? is not in the printable ASCII range */ .BI ((format)&&(SDL_PIXELFLAG(format)!=1))
This covers custom and other unusual formats.
Note that this macro double-evaluates its parameter, so do not use expressions with side-effects here.
Returns true if the format has alpha, false otherwise.
It is safe to call this macro from any thread.
This macro is available since SDL 3.2.0.
