[Qgis-developer] How to generate DTM iso-curves of QGis canvas ?

[Geo DrinX]

Hello all,


a simple question    :)

How to generate the SHP curves  of a DTM layer ,  only inside the current
QGis view,  quickly and faster ?

I tested with Processing >  Grass  > Nviz ...   but nothing appears  (after
10 minutes of waiting... )

Other ideas ?   For example,  the  "gdal_contour"  command  can also take as
input a window ?


Thank you in advance for any info about it

Roberto
