sdlxGetRenderLogicalPresentation function render

({int h, int mode, int w})? sdlxGetRenderLogicalPresentation(Pointer<SdlRenderer> renderer)

Get device independent resolution and presentation mode for rendering.

This function gets the width and height of the logical rendering output, or 0 if a logical resolution is not enabled.

Each render target has its own logical presentation state. This function gets the state for the current render target.

\param renderer the rendering context. \param w an int filled with the logical presentation width. \param h an int filled with the logical presentation height. \param mode a variable filled with the logical presentation mode being 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 3.2.0.
