Hi , i have tried with adding "get_target" in all possible places, but still "write_png" is saving zero byte png.i have attched the full code . Could you tell how to save that surface? //////////////////////////////////////////////////////////////////////////////////////// cairo_surface_t *image,*tsurf; static gdouble rotate_angle = 30.0,scale_factor = 1.5; GtkWidget* da; static gboolean on_expose_event(GtkWidget *widget,     GdkEventExpose *event,     gpointer data) {   cairo_t *cr; gint width,height; cr = gdk_cairo_create (widget->window); width = cairo_image_surface_get_width(image); height = cairo_image_surface_get_height(image);   cairo_translate(cr,width/2,height/2); cairo_scale(cr,scale_factor,scale_factor); cairo_rotate(cr,rotate_angle*M_PI/180.0); gtk_widget_set_size_request (da, width*scale_factor,height*scale_factor);  cairo_set_source_surface(cr, image,-width/2,-height/2);  cairo_paint(cr);   tsurf = cairo_get_target(cr); if(cairo_surface_status(tsurf) != CAIRO_STATUS_SUCCESS)  g_print(" nil surface \n"); else  cairo_surface_write_to_png (tsurf, "sticker.png");   cairo_destroy(cr);   return FALSE; } int main(int argc, char *argv[]) {   GtkWidget *window;   GtkWidget *fixed,*image1;   gint width,height;   image = cairo_image_surface_create_from_png(argv[1]);   width = cairo_image_surface_get_width(image);   height = cairo_image_surface_get_height(image);  g_print("width = %d height = %d \n",width,height);   gtk_init(&argc, &argv); window = gtk_window_new(GTK_WINDOW_TOPLEVEL); g_signal_connect(window, "destroy",       G_CALLBACK (gtk_main_quit), NULL); gtk_window_set_default_size(GTK_WINDOW(window), 800, 480); gtk_window_set_position(GTK_WINDOW(window), GTK_WIN_POS_CENTER); fixed=gtk_fixed_new(); gtk_container_add(GTK_CONTAINER(window),fixed); image1=gtk_image_new_from_file("bg.png"); gtk_fixed_put(GTK_FIXED(fixed),image1,0,0); da = gtk_drawing_area_new (); gtk_widget_set_size_request (da, width*2,height*2); gtk_fixed_put(GTK_FIXED(fixed),da,50,50); g_signal_connect(da, "expose-event",G_CALLBACK (on_expose_event), NULL);   gtk_widget_show_all(window); gtk_main(); cairo_surface_destroy(image);   return 0; }   /////////////////////////////////////////////////////////////////// <div class="gmail_quote">On Wed, Apr 16, 2008 at 6:32 PM, Gerdus van Zyl <<a href="mailto:gerdusvanzyl@gmail.com">gerdusvanzyl@gmail.com</a>> wrote: <blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">You can use get_target anywhere in on_expose, the write_to_png should be where it is now, after all painting is done before destroy. <div><div></div><div class="Wj3C7c"> </div></div></blockquote></div>
