so, I think I could fix the problem. What I do now is a complete reload of the image when getRasterData() is called (but not replacing the image4display). This way I get sure that always the rasterdata are delivered to Sextante which seemed to be the problem.
While testing I noticed that when I load an ascii grid and calculate the contours of that grid with sextante [own plugin that accesses the sextante function], then the delivered contours are displaced in the location (don't fit with the raster anymore). Not sure where this is to be attributed to? But when I calculate contours for KernelDensity raster (tif) that I created earlier out of points, then the contours seem to be in the right place. So maybe its some referencing info???? Alberto, could you check that? I hope tomorrows nightly build is fine with all the raster stuff stefan Stefan Steiniger wrote: > Hei Alberto, > > ok..
