NAME

SDL_BITSPERPIXEL - A macro to determine an SDL_PixelFormat

HEADER FILE

Defined in SDL3/SDL_pixels.h

SYNOPSIS

#include "SDL3/SDL.h"

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

DESCRIPTION

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.

RETURN VALUE

Returns the bits-per-pixel of format .

THREAD SAFETY

It is safe to call this macro from any thread.

AVAILABILITY

This macro is available since SDL 3.2.0.
