Every step is now > a subclass of QgsRasterInterface, with the advantage that several steps > can be chained in a QgsRasterPipe. Like that, the raster functionality > is nicely separated into different classes and it is easy to add/remove > elements in the pipe. The iteration over the raster parts is controlled > by QgsRasterIterator (because for high-resolution prints or analysis on > large datasets, it is impossible to keep everything in memory at once). > > Please report any issue you find in the branch to the developer mailing > list. > > Besides the changes in code architecture, there is also a new feature in > the raster-pipes-2 branch. It is now possible to write through > QgsRasterDataProvider (currently only supported by the gdal provider). > There is a 'save as...' function also for rasters now (though it is not > 100% complete at the moment). There is the option to save a raster in > one file or in tiles (the tiles are then saved in one directory and vrt > / pyramides are automatically created. Very usefull for saving the > contents of a WMS layer). > > Regards, > Marco > > -- > Dr. Marco Hugentobler > Sourcepole - Linux & Open Source Solutions > Weberstrasse 5, CH-8004 Zürich, Switzerland > [email protected] http://www.sourcepole.ch > Technical Advisor QGIS Project Steering Committee > > _______________________________________________ > Qgis-developer mailing list > [email protected] > http://lists.osgeo.org/mailman/listinfo/qgis-developer
