But it actually works?
I tested it on a small line vector and in the best case qgis freezes.
If the project is in wgs84 and the vector is not I get a crash (qgis
1.4, under linux)
I'm using trunk on linux here. And yes, it is working.
And trying both plugins on the same (multipolygon) project, I see some
differences and issues ...
- DPSimplify actually simplifies your data on the fly, and gives you the
option to either save it to a new shapefile or not (nice !)
- DPSimplify also reports the number of vertices reduced, which gives
you the option to lower or higher your tolerance (nice)
- DPSimplify seems to work only with line and polygons data (not multi*
)? (at first there was no layer in the dropdown, untill I added a (non
multi)polygon layer)
- DPSimplify the about-box raises an python exception here
Don't know when you add layers with a different projection to a map
(like you do: the plugin has to do the 'on the fly projection' itself I
think... this is a though case anyway)...
And to make myself clear: I do not want to discourage Alexander to
develop the plugin!! Because if I'm correct, the current vector-menu
stuff is actually cpp ported from the former python plugin as well.
I think the python plugins are a nice example and way for prototyping
stuff to either (but not nessecarily) being ported to trunk, and
hopefully raise interest for people to add functionality to qgis.

-----------------
this is one of the few (more) problems I found recently in the "vector"
toolbox so I'm about to open new tickets (there are already a few in the
trac). There is someone that plans, maybe at the hackfest, to solve this
issues?
