###### (This is the legacy documentation for SDL2, the previous stable version; [SDL3](https://wiki.libsdl.org/SDL3/) is the current stable version.) # SDL_RenderLogicalToWindow Get real coordinates of point in window when given logical coordinates of point in renderer. ## Header File Defined in [SDL_render.h](https://github.com/libsdl-org/SDL/blob/SDL2/include/SDL_render.h) ## Syntax ```c void SDL_RenderLogicalToWindow(SDL_Renderer * renderer, float logicalX, float logicalY, int *windowX, int *windowY); ``` ## Function Parameters | | | | | ------------------------------ | ------------ | -------------------------------------------------------------------- | | [SDL_Renderer](SDL_Renderer) * | **renderer** | the renderer from which the window coordinates should be calculated. | | float | **logicalX** | the logical x coordinate. | | float | **logicalY** | the logical y coordinate. | | int * | **windowX** | the pointer filled with the real X coordinate in the window. | | int * | **windowY** | the pointer filled with the real Y coordinate in the window. | ## Remarks Logical coordinates will differ from real coordinates when render is scaled and logical renderer size set ## Version This function is available since SDL 2.0.18. ## See Also - [SDL_RenderGetScale](SDL_RenderGetScale) - [SDL_RenderSetScale](SDL_RenderSetScale) - [SDL_RenderGetLogicalSize](SDL_RenderGetLogicalSize) - [SDL_RenderSetLogicalSize](SDL_RenderSetLogicalSize) ---- [CategoryAPI](CategoryAPI), [CategoryAPIFunction](CategoryAPIFunction), [CategoryRender](CategoryRender)
