问 用Gdk::Pixbuf::create_from_resource打开png图像时出错

EN

我正在尝试用Gdk：：Pixbuf：：create_from_resource读取png图像：

#include <iostream>
#include <gtkmm.h>
int main(int argc, char *argv[])
    auto app = Gtk::Application::create(argc, argv, "org.gtkmm.examples.base");
    Gtk::Window window;
    window.set_default_size(100, 100);
    try  {
        Glib::RefPtr<Gdk::Pixbuf> image
            = Gdk::Pixbuf::create_from_resource("image.png");
    } catch (const Glib::Error &error) {
        std::cerr << "Failed to load an image: " << error.what() << std::endl;
    return app->run(window);
}

但是出现了一个错误：

 $ ./a.out 
Failed to load an image: The resource at “image.png” does not exist
 $ ls -l
total 128
-rwxrwxr-x. 1 user user 36528 Jul 18 15:01 a.out
-rw-r--r--. 1 user user 88792 Jul 18 15:00 image.png
-rw-r--r--. 1 user user   449 Jul 18 15:00 main.cpp

gtkmm版本3.24.6
