Hi Tadej; Yes, I finally came up with the following, page = poppler_document_get_page(doc, page_num); poppler_page_get_size(page, &width, &height); cairo_surface_t *s; cairo_t *cr; s = cairo_image_surface_create(CAIRO_FORMAT_ARGB32, width, height); cr = cairo_create(s); poppler_page_render(page, cr); pixbuf = gdk_pixbuf_get_from_surface(s, 0, 0, width, height); image = gtk_image_new_from_pixbuf(pixbuf); with a build in GTK+-3. I just don't understand why there was a depreciation of the older code. Who makes these decisions?
