[Qgis-developer] Offset curve tool

[Denis Rouzaud]

Hi Marco,

I noticed a bug and Qgis crashes.

Here is a video http://youtu.be/DBbMg5rO8fU

The geometry of the line I played with is:

LINESTRING(554235.01669295 145547.73137862,554242.99020772 
145548.76938867,554245.33776182 145545.30016923,554245.49416371 
145544.76210759)

Greetings,

Denis

There is a new editing tool in the master branch.
The offset curve tool creates parallel shifts of linestrings and polygon 
rings ( single sided buffers with the geos function 
GEOSSingleSidedBuffer ). The tool can be applied to the edited layer 
(the geometries are modified) or also to background layers (creates 
copies of the lines / rings and adds it to the the edited layer). It is 
thus ideally suited for the creation of distance line layers.

Let me know about issues, suggestions, comments.

The work was kindly funded by the city of Uster (Switzerland).

Regards,
Marco
