img's Issues

images path needs to be relative

To ensure the program can work after being installed in /usr/local/bin/ on Linux and is able to look at the directory the user is in, you can modify the program to take an optional command line argument specifying the directory to load images from. If no argument is provided, the program will load images from the current working directory.

User's now need to specify the path after img command is used, like this:
img /path/to/images

new main code:

int main(int argc, char** argv) {
  char* dir_path = ".";
  if (argc > 2) {
    g_print("Usage: %s [directory]\n", argv[0]);
    return EXIT_FAILURE;
  } else if (argc == 2) {
    dir_path = argv[1];
  }

  load_images(dir_path);

  gtk_init(&argc, &argv);

  GtkWidget* window = gtk_window_new(GTK_WINDOW_TOPLEVEL);
  gtk_window_set_title(GTK_WINDOW(window), "Image Viewer");
  gtk_window_set_default_size(GTK_WINDOW(window), 300, 300);
  gtk_container_set_border_width(GTK_CONTAINER(window), 10);
  gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER);
  g_signal_connect(window, "destroy", G_CALLBACK(gtk_main_quit), NULL);

  image = gtk_image_new_from_pixbuf(pixbuf[current_image]);
  gtk_container_add(GTK_CONTAINER(window), image);

  g_signal_connect(window, "key-press-event", G_CALLBACK(on_key_press), NULL);

  gtk_widget_show_all(window);

  gtk_main();

  for (int i = 0; i < total_images; i++) {
    g_object_unref(pixbuf[i]);
  }

  return EXIT_SUCCESS;
}
