SDL_RenderLogicalToWindow

Get real coordinates of point in window when given logical coordinates of point in renderer.

Header File

Defined in SDL_render.h, but apps should only #include "SDL.h"!

Syntax

void SDL_RenderLogicalToWindow(SDL_Renderer * renderer, 
                                    float logicalX, float logicalY,
                                    int *windowX, int *windowY);

Function Parameters

renderer	the renderer from which the window coordinates should be calculated
logicalX	the logical x coordinate
logicalY	the logical y coordinate
windowX	the pointer filled with the real X coordinate in the window
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.
