Hi Ahmad, Did you build pyramids on your raster data to improve the performance?
Double click the raster layer and the layer properties dialogue opens. Then in the left iconbar go to "Pyramids". On the bottom right you can use the "Build Pyramids" button. If you already have pyramids, you will see them listed here. Hope this helps, Andreas On Sun, September 5, 2010 7:24 am, ahmad jauhari wrote: > Dear, > > I'm using ubuntu as OS, RAM 4GB, HD 320GB, RAM VGA 256MB. > I digitized on screen a sattelite image in big size (43 MB). > I got problem, the program crash or restart suddenly.
