Clipper processing of Horizontal Edges..+Front AddOutPt..

[Ignorant]

Angus,
Good evening.
I noticed you have started updating clipper..
I have a old Query ...must be lost somewhere in the discussions.!
in Horizontal edge sequence processing-->

cInt horz_left, horz_right;
bool is_left_to_right = ResetHorzDirection(horz, max_pair, horz_left, horz_right);
if (IsHotEdge(horz)) AddOutPt(horz, PointI(horz.curr_x, horz.bot.y));

while (true) {  //loops through consec. horizontal edges (if open)
    Active *e;


   I copied and pasted that code in my customized old clipper.I alwasy get duplicated vertices for closed input contours and odd/even parity,with the

AddOutPt(..)
Is it meant only for open polygons?. or other winding types.?

HI again Mahesh. As I've explained to you a couple of times before, I really don't have the resources to explain to you the internals of Clipper. I'm sorry to disappoint you but I'm fully occupied just maintaining and updating the two of open source libraries that I have published here at sourceforge.

O.K.
I understand .

Can any developer of this wondeful vatti clipper be generous enough with parting the answer to my query.?.Having just the source code is NOT helping.

Thanks. And I forgot to say I do appreciate your interest in Clipper. So I really am sorry I can't help you. Cheers.
