SDL_BYTESPERPIXEL3
A macro to determine an sdl_pixelformat
Usage
#include "SDL3/SDL.h"
#define SDL_BYTESPERPIXEL(format) .BI (SDL_ISPIXELFORMAT_FOURCC(format)?.BI ((((format) == SDL_PIXELFORMAT_YUY2) || .BI ((format)==SDL_PIXELFORMAT_UYVY)||.BI ((format) == SDL_PIXELFORMAT_YVYU) || .BI ((format)==SDL_PIXELFORMAT_P010))?2:1):(((format)>>0)&0xFF))
Header file
Defined in SDL3/SDL_pixels.h
Overview
Note that this macro double-evaluates its parameter, so do not use expressions with side-effects here.
FourCC formats do their best here, but many of them don't have a meaningful measurement of bytes per pixel.
Return value
Returns the bytes-per-pixel of format .
Thread safety
It is safe to call this macro from any thread.
