legacy function

What was the pre-2014 function for IsPolyClosed?

[Pat Stanford]

IsPolyClosed dates back to at least 2012. I think it is much older than that.

 

There was a post to the Vectorscript List in January 2013 that included this.

I found a polyline can be recognised as closed (with ispolyclosed) even though a segment can be shown as invisible and hence visually an open poly – so I wrote a more intelligent version – code below

Could be rewritten to be more general – I already know the number of vertices and you may not want the end point/invisible status.

function isclosedpoly(objH : HANDLE; vertnum : INTEGER; VAR vend,inviscnt : INTEGER) : BOOLEAN;

Var

  polyclosed : BOOLEAN;

  i,vnum : LONGINT;

begin

  inviscnt := 0;

  vend := 0;

  polyclosed := ispolyclosed(objH);

    vnum := vertnum-1;

    for i := 0 to vnum do begin

      if NOT GetVertexVisibility(objH,i) then begin

        polyclosed := FALSE;

        inviscnt := inviscnt + 1;

        vend := i + 1;

      end;

    end;

  isclosedpoly := polyclosed;

end;

Hmmmmm

 

http://developer.vectorworks.net/index.php/VS:IsPolyClosed says it's available from 2014. 

 

Or am I reading that wrong?

You are reading it right, I just think the documentation is wrong.
