I want to write directly to the screen buffer, that can change size at any time. If this is possible I would need a way to get the screen's dimensions beforehand so I can adjust the final images size.

If this is not possible, is there a way to create a simple image to write to and after finishing, push that to the screen? If you get back to me, a simple example will be greatly appreciated!

Maybe something similar to this SDL C code?

...
// edit an allocated buffer with colour data
(Uint8*)(m_window_surface->pixels)[offset + 0] = col.b;
(Uint8*)(m_window_surface->pixels)[offset + 1] = col.g;
(Uint8*)(m_window_surface->pixels)[offset + 2] = col.r;
...

// update the window with the buffer
SDL_UpdateWindowSurface(m_window);
