				if (!fonts_iter)
								continue; /* No fonts found in these 20 pages */
				do {
								/* Do something with font iter */
								g_print ("Font Name: %s\n", poppler_fonts_iter_get_name (fonts_iter));
				} while (poppler_fonts_iter_next (fonts_iter));
				poppler_fonts_iter_free (fonts_iter);
}

Parameters:

this	a FontInfo
n_pages	number of pages to scan
