Hi guys,

thanks for feedback and discussion.

DPSimplify was developed for one of GIS-Lab projects. There is some problems
with standart tool and Maxim ask me to write plugin with some
additional features.

We need this features in our project and I hope this can be usefull for other
users

We develop this plugin first or all for simplifing lines (a lot of
lines). Polygon
simplification is in TODO list. MultiLines are not supported yet.

I'll look on this tonight and try to fix

To make clear :-): we develop this plugin for our project and then share it with
community. As I see, maybe it will be better to integrate DPSimplify
into fTools.

Sorry for long reply
