sdlRenderCoordinatesToWindow function render

bool sdlRenderCoordinatesToWindow(Pointer<SdlRenderer> renderer, double x, double y, Pointer<Float> windowX, Pointer<Float> windowY,)

Get a point in window coordinates when given a point in render coordinates.

This takes into account several states:

• The window dimensions.
• The logical presentation settings (SDL_SetRenderLogicalPresentation)
• The scale (SDL_SetRenderScale)
• The viewport (SDL_SetRenderViewport)

\param renderer the rendering context. \param x the x coordinate in render coordinates. \param y the y coordinate in render coordinates. \param window_x a pointer filled with the x coordinate in window coordinates. \param window_y a pointer filled with the y coordinate in window coordinates. \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.
