    copied!<p>I want to save a webpage using webkit, gtk3 and cairo into a pdf. <hr/> What works: The visible part (visible in window) gets correctly printed into the pdf<hr/> What doesn't work, but should work: The invisible part (the part when you scroll down) should be printed into that pdf, too. Any ideas? <hr/> That's my code:</p> <pre><code>#include &lt;gtk/gtk.h&gt; #include &lt;webkit/webkit.h&gt; #include &lt;cairo-pdf.h&gt; static void save_as_pdf (GtkWidget *widget, const char *filename) { GtkAllocation allocation; printf("Saving PDF to file %s\n", filename); gtk_widget_get_allocation(GTK_WIDGET(widget), &amp;allocation); printf("height: %d width: %d\n", allocation.height, allocation.width); cairo_surface_t *surface = cairo_pdf_surface_create( filename, allocation.width, allocation.height); cairo_t *cr = cairo_create(surface); gtk_widget_draw(widget, cr); cairo_destroy(cr); cairo_surface_destroy(surface); } static void notifyProgressCb(WebKitWebView* webView, GParamSpec* pspec, GtkWidget* window) { float progress = webkit_web_view_get_progress(webView); printf("\x1b[1G\t\x1b[1G%f", progress * 100); fflush(stdout); if (progress == 1.0) save_as_pdf(window, "test.pdf"); } int main (int argc, char *argv[]) { GtkWidget *window; WebKitWebView *webView; gtk_init (&amp;argc, &amp;argv); window = gtk_window_new (GTK_WINDOW_TOPLEVEL); gtk_window_set_default_size(GTK_WINDOW(window), 1024, 768); webView = WEBKIT_WEB_VIEW(webkit_web_view_new()); gtk_container_set_resize_mode(GTK_CONTAINER(webView), GTK_RESIZE_PARENT); gtk_container_add(GTK_CONTAINER(window), GTK_WIDGET(webView)); g_signal_connect(webView, "notify::progress", G_CALLBACK(notifyProgressCb), webView); webkit_web_view_load_uri(webView, "http://www.heise.de"); g_signal_connect (window, "destroy", G_CALLBACK (gtk_main_quit), NULL); gtk_widget_show_all (window); gtk_main(); return 0; } </code></pre> <p>compile with: </p> <blockquote> <p>gcc <code>pkg-config --cflags --libs gtk+-3.0</code> <code>pkg-config --libs --cflags webkitgtk-3.0</code> yourfile.c</p> </blockquote>
