[mapserver-users] Length of a line calculation?

[Azimuth, Erwin Perik]

Hi V,

Had about the same question to the list a couple of days ago regarding 
getting the points of a shape.

If you found a way to get every point of a shape i'd really appreceate it ;-)

This i got from my Lowell F. :

Perl Mapscript example:
#
# Create shapefile object of existing data.
$shpfile = new shapefileObj("data", -1);
#
# Create shape object.
$shp = new shapeObj(-1);
#
# Retrieve shape into shape object.
$shpfile->get(1,$shp);
#
# Get first line.
my $line = new lineObj();
$line = $shp>{line};
#
# Get the first point of line.
my $point = new pointObj();
$point = $line->{point};
$px = $point->{x};
$py = $point->{y};
print "<br>POINT X=$px Y=$py<br>";
Doing such for each line of a shape and each point of
a line...
