That's great news! Concerning raster saving - will there be a mechanism for compressing files? It would be great if default compression schemes could be chosen for different file types, and an option at save time - sort of like image editors.
I had trouble building it with external spatialite, could only get it to compile with cmake -DWITH_INTERNAL_SPATIALITE=TRUE - does this require a special version of spatialite? regards, Etienne On Wed, Jul 18, 2012 at 12:13 PM, Marco Hugentobler <[email protected]> wrote: > Hi devs > > I'd like to announce the branch 'raster-pipes-2' in Radims repository > https://github.com/blazek/Quantum-GIS for testing. > Radim did a great job in refactoring the process of reading / resampling / > reprojecting / displaying / modifying raster layers.
