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

Header File

Syntax

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

Function Parameters

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.
