Hi Ticker, that's what I expected. Most shapes do not have too many points after line simplification. If I got that right most of the code in PolygonSplitterFilter is now obsolete. I think it would be better to move the functionality of PolygonSplitIfNeededFilter into it so that the history is kept.

In the examples I found, using backtracking to split the polygon gave very slight size improvements (best was about 0.05%) Ticker On Sat, 2017-02-04 at 06:10 -0700, Gerd Petermann wrote:

I can't do anything for a couple of days but I'd like to combine the methods.
sounds good to me. I once analysed why sub divs were split and found that most times it was because of "too many points" or "too many lines", not because of "too much data in rgn", but that might depend on style.
