Objet : Re: [UMN_MAPSERVER-USERS] Add polygon in shapefile
Should work although I don't remember exactly how. I think you have to
define
only one newLineObj and add to it all the vertex of your polygon PLUS the
first vertex. Then put this single closed line into your new shape.
Something like :
$line_a = ms_newLineObj();
$line_a->add($ecluse_sel_a);
$line_a->add($ecluse_sel_b);
$line_a->add($ecluse_sel_c);
$line_a->add($ecluse_sel_d);
$line_a->add($ecluse_sel_a);
$shape->add($line_a);
$zone_shp->addShape($shape);
$shape->free();
$zone_shp->free();
Hope it'll help.
