Hi,<BR>
<BR>
I used the code below to render a page of a pdf to a scrolled window in a gtk application of mine.<BR>
After downloading Ubuntu 12.04 I get that there is no more support for poppler_page_render_to_pixbuf().<BR>
I do know that we are supposed to use cairo. But how? How do I replace the code below with cairo?<BR>
<BR>
these are global variables<BR>
<BR>
static PopplerDocument *doc;<BR>
static PopplerPage *page;<BR>
GdkPixbuf *pixbuf;<BR>
GtkWidget *image;<BR>
<BR>
void open_pdf_file_on_lily_complete()<BR>
{<BR>
GtkWidget *viewport, *window, *hpane, *entry;<BR>
GtkScrolledWindow *scrolledwindow;<BR>
GError* err = NULL;<BR>
GString *link;<BR>
gchar *uri;<BR>
window = GTK_WIDGET(gtk_builder_get_object (builder, "window"));<BR>
link = make_ly_extension_into_pdf();<BR>
uri = g_filename_to_uri(link->str, NULL, NULL);<BR>
g_string_free(link, TRUE);<BR>
doc = poppler_document_new_from_file(uri, NULL, &err);<BR>
total_pages = 0;<BR>
width = 0.0;<BR>
height = 0.0;<BR>
if(doc!= NULL)<BR>
{<BR>
scrolledwindow = GTK_SCROLLED_WINDOW(gtk_builder_get_object (builder, "pdfscrollview")); <BR>
hpane = GTK_WIDGET(gtk_builder_get_object(builder, "ly_pdf_hpane"));<BR>
total_pages = poppler_document_get_n_pages(doc);<BR>
if(page_num > total_pages) page_num = 0;<BR>
page = poppler_document_get_page(doc, page_num);<BR>
poppler_page_get_size(page, &width, &height); <BR>
pixbuf = gdk_pixbuf_new(GDK_COLORSPACE_RGB, FALSE, 8, width, height);<BR>
poppler_page_render_to_pixbuf(page, 0, 0, width, height, 1, 0, pixbuf);<BR>
image = gtk_image_new_from_pixbuf(pixbuf);<BR>
viewport = gtk_bin_get_child(GTK_BIN(scrolledwindow));<BR>
if(viewport ) gtk_container_remove(GTK_CONTAINER(scrolledwindow), viewport);<BR>
gtk_scrolled_window_add_with_viewport(GTK_SCROLLED_WINDOW (scrolledwindow), image);<BR>
viewport = gtk_bin_get_child(GTK_BIN(scrolledwindow));<BR>
gtk_widget_add_events(viewport, GDK_POINTER_MOTION_MASK | GDK_BUTTON_PRESS_MASK);<BR>

g_signal_connect(G_OBJECT(viewport), "button-press-event", G_CALLBACK(mouse_down), image);<BR>
gtk_paned_set_position(GTK_PANED(hpane), 500);<BR>
window = GTK_WIDGET(gtk_builder_get_object (builder, "window"));<BR>
entry = GTK_WIDGET(gtk_builder_get_object (builder, "Entry"));<BR>
gchar *my_string = g_strdup_printf("%i", page_num + 1);<BR>
gtk_entry_set_text(GTK_ENTRY(entry), my_string);<BR>
gtk_widget_show_all (window);<BR>
}<BR>
