Convert the coordinates in an event to render coordinates.
Defined in <SDL3/SDL_render.h>
int SDL_ConvertEventToRenderCoordinates(SDL_Renderer *renderer, SDL_Event *event);
SDL_Renderer * | renderer | the rendering context. |
SDL_Event * | event | the event to modify. |
(int) Returns 0 on success or a negative error code on failure; call SDL_GetError() for more information.
Touch coordinates are converted from normalized coordinates in the window to non-normalized rendering coordinates.
Once converted, the coordinates may be outside the rendering area.
This function is available since SDL 3.0.0.
