In PowerPoint.pm extension to Win32::OLE I added a routine to create a line in a PowerPoint - like this it works!

sub add_line {
  my ($self, $options) = @_;

  return unless $self->slide;

  $options = {} unless ref $options eq 'HASH';

  my $new_line = $self->slide->Shapes->AddLine($options->{x1}, $option
+s->{y1}, $options->{x2}, $options->{y2});

  $new_line->{Line}{ForeColor}{RGB}=RGB($options->{forecolor}) if(defi
+ned $options->{forecolor});

  $new_line->{Line}{Weight}=$options->{weight} if(defined $options->{w
+eight});

  $new_line->{Line}{Pattern}=$options->{pattern} if(defined $options->
+{pattern});

  return $new_line;
}

Now I'm trying to add a routine to make a polyline ... (so I can draw arbitrary and not just mso Shapes) and I coded it like this:

sub add_polyline {
  my ($self, $options) = @_;

  return unless $self->slide;

  $options = {} unless ref $options eq 'HASH';

  my $new_poly=$self->slide->Shapes->AddPolyline($options->{points});

  $new_poly->{Line}{ForeColor}{RGB}=RGB($options->{forecolor}) if(defi
+ned $options->{forecolor});

  $new_poly->{Line}{Weight}=$options->{weight} if(defined $options->{w
+eight});

  $new_poly->{Line}{Pattern}=$options->{pattern} if(defined $options->
+{pattern});

  if(defined $options->{fillcolor})
  {
    $new_poly->{Fill}{ForeColor}{RGB}=RGB($options->{fillcolor});
  }
  else
  {
    $new_poly->{Fill}{Transparency}=1;
  }

  return $new_poly;
}

Which does not work. The argument needed by the microsoft routine AddPolyline is something called a "SafeArrayOfPoints" in the docos.

I've tried an array, a two-dimensional array, and array reference ... nothing works.

Can anyone help?
