sdlxGetTextureSize function render

({double h, double w})? sdlxGetTextureSize(Pointer<SdlTexture> texture)

Get the size of a texture, as floating point values.

\param texture the texture to query. \param 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. \param 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 true on success or false on failure; call SDL_GetError() for more information.

\threadsafety This function should only be called on the main thread.

\since This function is available since SDL 3.2.0.

extern SDL_DECLSPEC bool SDLCALL SDL_GetTextureSize(SDL_Texture *texture, float *w, float *h)

  }
