нужно переделать код из SDL 1.2 в SDL 2.0.12

include "Project.h"
 
#include "Image.h"
class Image;
 
class Graphics
{
private:
    SDL_Surface* Screen;

    bool DrawImage(Image* img, int x, int y, int startX, int startY, int endX, int endY);
 
    void Flip();
};
 
Graphics::Graphics(int width, int height)
{
    SDL_Init(SDL_INIT_EVERYTHING);
    Screen = SDL_SetVideoMode(width, height, 32, SDL_HWSURFACE | SDL_DOUBLEBUF); //ошибки
}
 
Image* Graphics::NewImage(char* file)
{
    Image* image = new Image();
    image->surf = SDL_DisplayFormat(SDL_LoadBMP(file)); //ошибка

        SDL_MapRGB(image->surf->format, r, g, b));
 
    return image;
}
 
bool Graphics::DrawImage(Image* img, int x, int y)
{
    if (Screen == NULL || img->surf == NULL)
        return false;
