SDL_ISCOLORSPACE_MATRIX_BT601 - Man Page

SDL_ISCOLORSPACE_MATRIX_BT601 — A macro to determine if an SDL_Colorspace
uses BT601 (or BT470BG) matrix coefficients.

Defined in SDL3/SDL_pixels.h

#include "SDL3/SDL.h"

#define SDL_ISCOLORSPACE_MATRIX_BT601(cspace)        (SDL_COLORSPACEMATRIX(cspace) == SDL_MATRIX_COEFFICIENTS_BT601 || SDL_COLORSPACEMATRIX(cspace) == SDL_MATRIX_COEFFICIENTS_BT470BG)

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

Returns true if BT601 or BT470BG, false otherwise.

It is safe to call this macro from any thread.

This macro is available since SDL 3.2.0.
