getLogicalSize method

Point<double> getLogicalSize()

Get device independent resolution and presentation mode for rendering.

This function gets the width and height of the logical rendering output, or the output size in pixels if a logical resolution is not enabled.

\param renderer the rendering context. \param w an int to be filled with the width. \param h an int to be filled with the height. \param mode the presentation mode used. \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 3.1.3.
