SDL_QueryTexture

Query the attributes of a texture.

Header File

Defined in SDL_render.h, but apps should use #include <SDL3/SDL.h>

int SDL_QueryTexture(SDL_Texture *texture, SDL_PixelFormatEnum *format, int *access, int *w, int *h);

texture	the texture to query
format	a pointer filled in with the raw format of the texture; the actual format may differ, but pixel transfers will use this format (one of the SDL_PixelFormatEnum values). This argument can be NULL if you don't need this information.
access	a pointer filled in with the actual access to the texture (one of the SDL_TextureAccess values). This argument can be NULL if you don't need this information.
w	a pointer filled in with the width of the texture in pixels. This argument can be NULL if you don't need this information.
h	a pointer filled in with the height of the texture in pixels. This argument can be NULL if you don't need this information.

Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.

This function is available since SDL 3.0.0.

SDL_Texture* source;

// loading etc ...

int w, h;
SDL_QueryTexture(source, NULL, NULL, &w, &h);
