如何将SDL_Surface转换为GtkImage

#include <SDL.h>
#include <gtk/gtk.h>

GtkWidget* sdlSurfaceToGtkImage(SDL_Surface* surface) {
    // 获取SDL_Surface的像素数据
    Uint32* pixels = (Uint32*)surface->pixels;
    int width = surface->w;
    int height = surface->h;

    // 创建一个新的GdkPixbuf对象
    GdkPixbuf* pixbuf = gdk_pixbuf_new(GDK_COLORSPACE_RGB, FALSE, 8, width, height);
    guchar* pixels_pixbuf = gdk_pixbuf_get_pixels(pixbuf);

    // 将像素数据复制到GdkPixbuf对象中
    for (int y = 0; y < height; y++) {
        for (int x = 0; x < width; x++) {
            Uint32 pixel = pixels[y * width + x];
            guint8 red, green, blue, alpha;
            SDL_GetRGBA(pixel, surface->format, &red, &green, &blue, &alpha);
            int offset = (y * gdk_pixbuf_get_rowstride(pixbuf)) + (x * gdk_pixbuf_get_n_channels(pixbuf));
            pixels_pixbuf[offset] = red;
            pixels_pixbuf[offset + 1] = green;
            pixels_pixbuf[offset + 2] = blue;
            pixels_pixbuf[offset + 3] = alpha;
        }
    }

    // 创建一个新的GtkImage对象
    GtkWidget* image = gtk_image_new_from_pixbuf(pixbuf);

    // 释放GdkPixbuf对象
    g_object_unref(pixbuf);

    return image;
}

int main(int argc, char* argv[]) {
    // 初始化SDL
    SDL_Init(SDL_INIT_VIDEO);

    // 创建一个SDL_Surface对象
    SDL_Surface* surface = SDL_CreateRGBSurface(0, 640, 480, 32, 0, 0, 0, 0);

    // 在SDL_Surface上绘制图像（此处省略具体绘制过程）

    // 将SDL_Surface转换为GtkImage
    GtkWidget* image = sdlSurfaceToGtkImage(surface);

    // 创建一个GTK+窗口
    GtkWidget* window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
    gtk_window_set_default_size(GTK_WINDOW(window), 640, 480);

    // 将GtkImage添加到窗口中
    gtk_container_add(GTK_CONTAINER(window), image);

    // 显示窗口和图像
    gtk_widget_show_all(window);

    // 进入GTK+主循环
    gtk_main();

    // 释放SDL_Surface对象
    SDL_FreeSurface(surface);

    // 清理SDL
    SDL_Quit();

    return 0;
