scale window sdl2

To scale a window using SDL2 in C++, you can follow the steps below:

1. Include the necessary header files:
2. #include <SDL.h> for SDL2 functionalities

3. #include <SDL_image.h> if you plan to use images

4. Initialize SDL2:

5. Call SDL_Init(SDL_INIT_VIDEO) to initialize the video subsystem

6. Create a window:

7. Use SDL_CreateWindow() to create a window with the desired dimensions and flags

8. The function takes parameters such as window title, initial position, width, height, and flags

9. Create a renderer:

10. Use SDL_CreateRenderer() to create a renderer for the window

11. The function takes parameters such as the window to attach the renderer to, the index of the rendering driver (-1 for the first available driver), and flags

12. Set the logical size:

13. Use SDL_RenderSetLogicalSize() to set the logical size of the rendering area

14. The function takes parameters such as the renderer and the desired logical width and height

15. Scale the window:

16. Use SDL_RenderSetScale() to set the scaling factors for the renderer

17. The function takes parameters such as the renderer and the desired horizontal and vertical scaling factors

18. Render to the window:

19. Use SDL_RenderClear() to clear the renderer

20. Use SDL_RenderPresent() to present the rendered content to the window

21. Handle events:

22. Use an event loop to handle events such as window close events or user input

23. You can use SDL_PollEvent() to poll for events and handle them accordingly

24. Clean up:

25. Use SDL_DestroyRenderer() to destroy the renderer
26. Use SDL_DestroyWindow() to destroy the window
27. Call SDL_Quit() to clean up and exit SDL2

Please note that these steps provide a general outline of how to scale a window using SDL2 in C++. You may need to modify the code according to your specific requirements and project structure. Additionally, it's always a good practice to check for errors and handle them appropriately to ensure smooth execution of your program.
