Re: Computing character height

Mon Dieu, C'est Magnifique!

Merci!

P.S.: Yeah, I'm still learning Pango concepts. Next time: clusters and 
glyphs and characters...

Just for the records:

void text_rectangles(cairo_t * cairo, PangoLayout * layout)
{
        PangoLayoutIter * iter = NULL;
        PangoRectangle extents;

        cairo_set_source_rgb(cairo, 0.5, 0.0, 0.0);
        cairo_set_line_width(cairo, 0.5);

        iter = pango_layout_get_iter(layout);
        do {
                pango_layout_iter_get_cluster_extents(iter, &extents, NULL);
                pango_extents_to_pixels(&extents, NULL);
		cairo_rectangle(cairo, extents.x, extents.y, extents.width, 
extents.height);
        } while (pango_layout_iter_next_cluster(iter));

        cairo_stroke(cairo);

        pango_layout_iter_free(iter);
}
