Anita If you algorithm is of general interest and you don't mind sharing it, we can put it in the SEXTANTE code and distribute it along with the other ftools algorithms. If you do not want to have it in the ftools group, then you can also create you own algorithm provider in its own plugin (the

[Qgis-developer] Creating a new raster qith QgsRasterLayer?

Until now I've mostly created vector layers on QGIS, delegating raster creation to custom GDAL utilities. Recently I looked into QgsGdalProvider and I saw that it exposes the QgsRasterDataProvider::Create capability. I wonder if it's possible to create a brand new raster (geotiff or what else)

Hi Bernhard, Yes - this is definitely on our radar. We need this for our waste-water application. It is called data defined symbology and used to work with the old symbology. With the new symbology, data defined symbology is more complex to implement as we have symbol levels. I'll contact
