Query the attributes of a texture.
int SDL_QueryTexture(SDL_Texture *texture, Uint32 *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.
