scan

Scans the document associated with this for fonts.

At most n_pages will be scanned starting from the current iterator. iter will point to the first font scanned.

Here is a simple example of code to scan fonts in a document

font_info = poppler_font_info_new (document);
while (poppler_font_info_scan (font_info, 20, &fonts_iter)) {
        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
iter	return location for a FontsIter

Returns:

true, if there are more fonts left to scan
