GnomeCanvasGroup * group = group;
GnomeCanvasItem;
GPPath * bpath;

bpath = gp_path_new();

bpath->path[0].code = ART_MOVE_OPEN;
bpath->path[0].x1 = x01;
bpath->path[0].y1 = y01;
bpath->path[0].x2 = x02;
bpath->path[0].y2 = y02;
bpath->path[0].x3 = x03;
bpath->path[0].y3 = y03;

bpath->path[1].code = ART_CURVETO;
bpath->path[1].x1 = x11;
bpath->path[1].y1 = y11;
bpath->path[1].x2 = x12;
bpath->path[1].y2 = y12;
bpath->path[1].x3 = x13;
bpath->path[1].y3 = y13;

bpath->path[2].code = ART_END;
bpath->path[2].x1 = x21;
bpath->path[2].y1 = y21;
bpath->path[2].x2 = x22;
bpath->path[2].y2 = y22;
bpath->path[2].x3 = x23;
bpath->path[2].y3 = y23;

item = gnome_canvas_item_new(group,
                             gnome_canvas_bpath_get_type(),
                             "bpath", bpath,
                             "fill_color", "#ff0000",
                             NULL);
