I'm trying to draw a road shapefile over a geotiff using Goo::Canvas and Geo::Shapefile. It seems when I run this part of the script it crashes perl. Specifically, it seems around the drawing of the Polyline. Maybe the monks can help me figure out why?
my $road_group = Goo::Canvas::Group->new($root); my $shapefile = new Geo::ShapeFile("UT_Southeast"); for(1 .. $shapefile->shapes()) { my @shape = (); my $shape = $shapefile->get_shp_record($_); #for(1 .. $shape->num_parts) { foreach my $p(1 .. $shape->num_parts){ if ($shape->y_max <= $top_lat && $shape->y_min >= $bot_lat && +abs($shape->x_max) <= abs($top_long) && abs($shape->x_min) <= abs($bo +t_long)){ my @part = $shape->get_part($p); print $shape->dump; #draw the lines for(@part) { #print $_->X,' ',$_->Y,"\n"; push(@shape,[$_->X,',',$_->Y]); } foreach (@shape){ print @$_,"\n"; } my $num_points = @shape; print "$num_points\n"; my $road = Goo::Canvas::Polyline->new($road_group,FALSE,$n +um_points,@shape); } } }
