image printing

[Alexander Kuleshov]

Hello,

I need to print image in my gtk+ application. I have code:

GList* list;

void begin_print (GtkPrintOperation * oper, GtkPrintContext * context,
                       gint nr, gpointer user_data)
{
   GdkPixbuf* pixbuf = gdk_pixbuf_new_from_file("home/shk/photo.jpg", NULL);

   list = g_list_prepend (list, pixbuf);
   gtk_print_operation_set_n_pages(oper,1);

   g_object_unref(pixbuf);
}

Then draw-page:

void draw_page (GtkPrintOperation * oper, GtkPrintContext * context,
                       gint nr, gpointer user_data)
{
     cairo_t *cr = gtk_print_context_get_cairo_context (context);
        gdk_cairo_set_source_pixbuf(cr,
(GdkPixbuf*)g_list_nth_data(list, 0), 0, 0);

   cairo_paint (cr);
}

and print setup:

void   print_pixbuf(GtkWidget* widget, MainWin* mw)
{
    GtkPrintOperation *op;
    GtkPrintOperationResult res;

    op = gtk_print_operation_new ();

    gtk_print_operation_set_unit (op, GTK_UNIT_MM);
    g_signal_connect (op, "begin-print", G_CALLBACK (begin_print), mw);
   g_signal_connect (op, "draw-page", G_CALLBACK (draw_page), mw);

    res = gtk_print_operation_run (op,
GTK_PRINT_OPERATION_ACTION_PRINT_DIALOG, mw, NULL);

   g_object_unref (op);
}

But when i try to print image, i see segfault:

IA__gdk_cairo_set_source_pixbuf (cr=0x8333c00, pixbuf=0x0, pixbuf_x=0,
pixbuf_y=0) at gdkcairo.c:210 210 gdkcairo.c: No such file or
directory. in gdkcairo.c

What's wrong?

Thank you
